Mr. Charlie Bevis, Supervisor

Tallahassee, Florida
Dear Mr. Bevis:
One of the first cities in Florida to experience a failure of a
well field through salt water intrusion was the city of St. Peters-
burg.
This large population center is located on a narrow peninsula
and the heavy draft of water for municipal and other rapidly de-
veloping enterprises, such as tourist and beach attractions, perm-
anent homes, and large agricultural and other water-using busi-
nesses encouraged the county commissioners and officials of the
larger cities of the county to inventory its water supply.
This water resource study, undertaken by the United States
and Florida Geological Surveys at the request of the citizens of
Pinellas County is being published as Report of Investigations No.
12. It is a pleasure to record that a large source of potable water
was discovered during the investigation, lying wholly within the
boundaries of Pinellas County, and an adequate supply is available
for an increased development of the economy of the area.
Respectfully,
Herman Gunter, Director

GROUND-WATER RESOURCES

PINELLAS COUNTY, FLORIDA

ABSTRACT
Pinellas County comprises a land area of 290 square miles along
the west coast of Florida, and forms a peninsula between Old Tampa
Bay and the Gulf of Mexico. It is underlain by a series of limestone
formations having a total thickness of several thousand feet. The
upper several hundred feet of the limestone consists of the Suwan-
nee limestone of late Oligocene age and the Tampa formation of
early Miocene age. South of Palm Harbor these limestones are over-
lain by clays and sandy clays of middle and late Miocene age. A
veneer of Pliocene(?) and Pleistocene sands and shelly sands,
ranging in thickness from several feet to more than 50 feet, overlies
the clays and sandy clays in the area south of Palm Harbor and
overlies.the Tampa formation' in the area north of Palm Harbor.
The Tampa and Suwannee limestones constitute the principal
source of water in the county. Water in these formations occurs
under water-table conditions in most of the area north of Palm
Harbor and west of Lake Tarpon, and under artesian conditions in
the area south of Palm Harbor. Where the water is under water-
table conditions the formations are recharged locally by rain. In
the area south of Palm Harbor, where the clays and sandy clays con-
fine the water in the limestones under pressure, water enters the
formations wherever the confining beds are discontinuous or absent,
but principally through sinkholes in the vicinity of Coachman.
The artesian water in the Tampa formation and Suwannee lime-
stone in the area north of Old Tampa Bay and east of Lake Tarpon
is derived principally from recharge that enters the limestones in
northern Hillsborough County and southern Pasco County.
In the area north of Palm Harbor and west of Lake Tarpon, the
water table is relatively low, ranging from about 2 feet to about
6 feet above sea level. Over the rest of the county, where the water

clature of the Florida Geological Survey. It conforms also to the nomenclature
of the U. S, Geological Survey except that Tampa formation is used in this
report instead of Tampa limestone.
FLORIDA GEOLOGICAL SURVEY
in the limestones is under artesian pressure, the piezometric sur-
face ranges from about 2 feet above sea level in some areas near
the coast to more than 22 feet in the northeastern part of the county.
The problem of salt-water encroachment first became prominent
in Pinellas County between 1920 and 1930 when the early municipal-
supply wells of St. Petersburg began to yield salty water. Areas
on both coasts of the county have been affected by the encroach-
ment. These include: (1) a small area that extends in a north-
easterly direction from the coast south of Palm Harbor almost to
Lake Tarpon; (2) most of the area between Indian Rocks and Long
Bayou; (3) an area along the southeastern coast of the county be-
ginning in the vicinity of Lake Maggiore and extending northward
for more than 15 miles; and (4) a small area at the north end of
Old Tampa Bay about 2 miles west of Oldsmar.
The chloride content of the water from many of the deep wells
in the areas of salt-water encroachment is more than 500 parts per
million, whereas the chloride content of uncontaminated ground
water in the county is generally less than 50 ppm. Uncontaminated
ground water generally contains less than 300 ppm of dissolved
solids and has a total hardness of less than 250 ppm.
INTRODUCTION
The difficulty of locating and preserving adequate potable water
supplies is a problem confronting many of Florida's coastal com-
munities. In some areas the problem is one of finding satisfactory
water in sufficient quantity to supply the needs of the community;
in others, the problem is one of protecting supplies already developed
against an encroachment of salt water. The presence of naturally
salty ground water in some of the water-bearing formations in
Brevard, Sarasota, Charlotte, Lee, and other counties of the State
makes the finding of satisfactory ground-water supplies difficult.
In Pinellas County, however, the problem is primarily one of pre-
venting the encroachment of salt water into the water-bearing
formations.
Salt-water encroachment began first in the southern part of
the county in the early twenties. By 1930 it had so seriously affected
the St. Petersburg supply that a new well field was developed for
the city at Cosme, more than 20 miles north of the city, in Hills-
REPORT OF INVESTIGATIONS NO. 12
borough County. Since 1930 salt water has continued to move into
the water-bearing formations as a result of a gradual increase in
the withdrawal from wells. Among the other public water supplies
in the county that have increased in salinity are those of Clearwater,
Tarpon Springs, Pinellas Park, and the Pinellas County Water Sys-
tem. In addition, many wells supplying water for irrigation and
domestic uses have also been affected by the encroachment.
PURPOSE AND SCOPE OF INVESTIGATION
The investigation leading to this report was begun in 1944 by
the United States Geological Survey in cooperation with the Florida
Geological Survey and the Board of County Commissioners of
Pinellas County. Its primary purpose was to determine the extent
to which salt water had encroached into the water-bearing forma-
tions and, to evaluate the factors governing encroachment. An
investigation of the surface-water resources of the county also was
begun in 1944 by the Surface Water Branch of the U. S. Geological
Survey.
The field work of the ground-water investigation consisted of:
1. The collection of information on the location, the depth and
diameter, and other pertinent facts on the existing wells in the
county.
2. Analyses of the chloride content of water from all flowing wells
and from most of the wells equipped with pumps.
3. Repeated analyses of the chloride content of water from se-
lected wells.
4. Measurements of the water level in all open wells that could
be found.
5. The collection and geologic study of rock cuttings from 34
wells.
6. The installation of eight automatic water-stage recorders.
PERSONNEL AND ACKNOWLEDGMENTS
Most of the field work of the investigation was done by P. C.
Smith, of the U. S. Geological Survey, whose death in March 1949
FLORIDA GEOLOGICAL SURVEY
prevented his writing the report. Earlier field work was done by
A. G. Unklesbay and T. C. Wiggins, also of the Federal Survey.
R. C. Heath collected the data on the piezometric surfaces, the
terraces, and the geology and prepared the report. The investi-
gation was made under the immediate supervision of H. H. Cooper,
Jr., District Engineer, and under the general supervision of A. N.
Sayre, Chief of the Ground Water Branch, U. S. Geological Survey,
and Herman Gunter, Director of the Florida Geological Survey.
Helpful assistance was given throughout the investigation by
W. A. McMullen, who was then County Engineer of Pinellas County.
A. R. Swartz, of the U. S. Department of Agriculture, Soil Con-
servation Service, placed his office facilities at the disposal of the
authors during the investigation, and F. S. Mann, also of the Soil
Conservation Service, assisted in making water-level measurements.
A. O. Dunlap and other well drillers saved cuttings and gave infor-
mation on numerous wells. Also, information on wells was given by
many public officials and private individuals.
PREVIOUS INVESTIGATIONS
The water resources and geology of Pinellas County have been
treated briefly in previous reports of the Florida Geological Survey
and the U. S. Geological Survey. A report by Matson and Sanford
(1913, pp. 319-325) describes the geology and ground water of
Hillsborough County, which at that time included the area that is
now Pinellas County. A report by Sellards and Gunter (1913, pp.
258-262) contains a generalized map of the area of artesian flow
and describes the water-bearing formations. Chemical analyses of
23 samples of water from Pinellas County are listed in a report by
Collins and Howard (1928, p. 224). A recent report on the chemical
character of Florida waters (Black and Brown, 1951, pp. 91-93)
contains 81 analyses of water samples from Pinellas County. A
report by Stringfield (1933, pp. 13-17) gives a general discussion
of the occurrence of ground water in the county and calls attention
to the problems that need investigation. A map of the piezometric
surface of the principal artesian aquifers in the Florida peninsula
and a discussion of recharge and discharge areas are included in a
report by Stringfield (1936). The geologic formations that crop
out in Pinellas County have been described by Cooke (1945, pp. 131,
192, 224). A report by Ferguson and others (1947, p. 137) describes
two of the largest springs in the county and gives chemical analyses
of their waters.
REPORT OF INVESTIGATIONS NO. 12
GEOGRAPHY
LOCATION AND AREA
Pinellas County is approximately in the center of the west coast
of Florida (see fig. 1) and includes the peninsula that separates
Old Tampa Bay from the Gulf of Mexico. It has a total of 439
square miles, of which only 290 square miles, or 185,600 acres, is
land. The county has a coast line of 128 miles, a length of about 40
miles, and an average width of about 7 miles.
CLIMATE
The climate of the county is subtropical. The average annual
rainfall at Tarpon Springs during the 51-year period beginning in
1892, according to the records of the U. S. Weather Bureau, was
51.20 inches. The average annual rainfall at St. Petersburg over
the 32-year period beginning in 1915 was 53.24 inches. Thus, the
Figure 1.-Map of Florida showing location of Pinellas County.
FLORIDA GEOLOGICAL SURVEY
average annual rainfall over a long period of years is about the same
in the northern part as it is in the southern part of the county.
However, in any particular year the amount falling on one part
may differ from that falling on another part by as much as 15
inches, or more. In 1941, for instance, Tarpon Springs had 62.46
inches of rainfall, whereas St. Petersburg had only 45.77 inches.
The months of heaviest rainfall are June through September. The
mean temperature in the county is 71.7 F.
TOPOGRAPHY
The topography of Pinellas County may be divided into three
types: hilly uplands, characteristic of the area from Oakhurst to
Palm Harbor; a flat upland, around St. Petersburg; and level low-
lands, characteristic of the area north and east of Pinellas Park.
All of these subdivisions lie within "The Terraced Coastal Low-
lands" (see Vernon, 1951, p. 16.).
The principal upland area, here referred to as the "Pinellas
ridge," is an area ranging from 3 to 4 miles in width, bordering the
Gulf of Mexico from the vicinity of Oakhurst to the vicinity of
Palm Harbor. It consists of gently rolling hills formed by the erosion
of small streams, and of sinkholes formed by collapse of the surface
formations into limestone caverns. Altitudes on the ridge range
from about 25 feet to as much as 100 feet above sea level. However,
the summits of most of the hills are between 80 and 95 feet above
sea level, their concordance indicating that the Pinellas ridge may
once have been a continuous, relatively level upland. The highest
altitude in Pinellas County, as recorded on the topographic maps
of the U. S. Corps of Engineers, is 97 feet, on State Highway 580
about 4 miles east of Dunedin. The maximum relief on the ridge is
in Sec. 5, T. 28 S., R. 16 E., near the southwest shore of Lake Tar-
pon, where the altitude changes more than 40 feet in less than a
tenth of a mile. North of Pinellas ridge, and separated from it, is a
line of small hills, extending around the north end of Lake Tarpon,
whose summits range in altitude from about 20 to about 60 feet. Al-
though these hills are not a part of the ridge, they give the area in
which they occur a topography similar to that of the ridge.
The upland in the vicinity of St. Petersburg has low relief, the
maximum altitude being about 50 feet. This area is roughly circular
and has a diameter of about 5 miles.
Surrounding the upland areas are areas of low-lying level land
and swamps, which range in altitude from sea level to about 25
feet. These level lowlands are best exemplified and have the greatest

areal extent north and west of St. Petersburg and south and east
of Lake Tarpon.
TERRACES
During Pleistocene time the sea stood above and below its present
level, submerging greater and lesser portions of the land according
to its height. Whenever it remained relatively stationary for a
long period, waves and currents washing back and forth across the
sea floor formed an essentially level surface, called a "terrace."
Upon the retreat of the sea to a lower level each terrace emerged
as a level plain having a slight seaward dip. The landward margin
of such a terrace is the abandoned shoreline, which is generally
marked by a low scarp.
Discussions of the Pleistocene history and the terraces in
Florida are included in a report by Cooke (1945, pp. 245-312) and
Vernon (1951, pp. 19-32). Three of these terraces, the Pamlico,
Penholoway, and Wicomico, have been recognized by the senior
author in Pinellas County. The Pamlico terrace, whose shoreline
is approximately 25 feet above present sea level, is well preserved
in Pinellas County. The Penholoway may be associated with a
scarp that is present at several places in the county between 60
and 70 feet above sea level. The Wicomico terrace, built when the
sea stood approximately 100 feet above its present level, is repre-
sented by the highest surfaces of the Pinellas ridge.
The terraces are not readily recognizable on the topographic
maps of the county because the maps have 20-foot contour inter-
vals and hence do not show sufficient detail. In order to identify
and delineate the terraces, several traverses across the county were
made with an aneroid barometer. However, the topographic maps
were used to delineate them in the relatively inaccessible areas
where traverses were not made. The boundaries of the terraces are
shown in figure 2.
When the sea stood 100 feet higher than it does today, during
Wicomico time, the Pinellas ridge was a shoal about 40 miles west
of the nearest land, which consisted of a large island located in
what is now the relatively high lake region of central Florida. Much
of the shoal, particularly in the area northeast of Dunedin, was so
near sea level that some parts of it may have emerged during low
tide.
During the formation of the Penholoway terrace, which is
believed by Cooke (1945, p. 17) to have occurred during the Sanga-

REPORT OF INVESTIGATIONS NO. 12
mon stage interglaciall), about 200,000 years ago, the Pinellas ridge
was a chain of islands about 35 miles west of the mainland. Rem-
nants of a scarp that was formed during that time are, among other
places, at the following locations: about three-fourths of a mile
east of Palm Harbor on State Road 580; about 3 miles east of
Dunedin and also about 5 miles east of Dunedin; near the south
side of Largo on U. S. Highway 19; and about a quarter of a mile
north of Walsingham on U. S. Highway 19.
Cooke (1945, p. 292) recognized the Talbot terrace having a
scarp based at 42 feet. The senior author recognized no such terrace
in Pinellas County but included in the Pamlico terrace deposits
which Cooke might have considered to be Talbot. However, at
several places in the county the base of the Pamlico terrace is at
an altitude of 42 feet. The most notable example is the segment
of the scarp on State Road 580 about half a mile west of Tampa Bay.
There, the land surface rises from 40 to 52 feet above sea level in
less than a tenth of a mile. Another is near the intersection of
38th Avenue West and 44th Street North in St. Petersburg, where
the surface rises from 42 to 53 feet above sea level.
The Pamlico is the best preserved and therefore the most easily
recognizable terrace in Pinellas County. Its landward margin,
which coincides with the shoreline of the Pamlico sea, occurs at the
base of a low scarp that is well preserved at many places in the
county. The scarp is well preserved, for example, along Clearwater
Harbor in the vicinity of Clearwater, where it is rarely more than
several hundred feet inland from the present shore, and also along
the west side of Old Tampa Bay. However, it is not generally as
well preserved on the bay as on the gulf.
The line of hills (see fig. 2) that extends from the Pinellas ridge
along the west and north shores of Lake Tarpon may have been
formed, as a bar (Leverett, 1931, p. 21) or a spit, of material trans-
ported from the Pinellas ridge by an ocean current flowing in a
northerly direction. The change in trend of the islands from north
to east around the north end of Lake Tarpon was probably caused
either by local currents, such as would accompany eastward-moving
storms, or by a change in direction of the dominant'ocean current
during the formation of the Pamlico terrace. The building of sand
dunes has increased the altitude of some of these islands by as
much as 15 to 40 feet above the level of the sea at that time.
FLORIDA GEOLOGICAL SURVEY
DRAINAGE
The northern part of the county is drained underground by
solution channels in the Tampa formation, and by the Anclote
River. The Pinellas ridge is drained by a series of short creeks on
both the east and west coasts. Sinkholes and lakes also receive some
of the surface drainage of the ridge, particularly in the area around
Coachman, where part of the rainfall percolates downward through
sinkholes into the underlying formations. The southern part of
the peninsula is drained by Long Bayou and Cross Bayou and their
short natural tributaries, and by the network of canals that have
been dug to drain the previously swampy areas in the vicinity of
Pinellas Park.
GEOLOGY
The geologic formations that are exposed in Pinellas County
range from deposits of early Miocene age (the Tampa formation)
to undifferentiated deposits of Pliocene(?) and Pleistocene age.
Those below the Pliocene(?) and Pleistocene are exposed in a series
of belts across the county (fig. 3). The boundaries of the forma-
tions as shown on figure 3 are generalized, but probably represent
the true boundaries rather closely. Information on which the geo-
logic map was drawn was obtained from 34 well logs and from a
study of several outcrops of the formation. A geologic cross section
showing the vertical extent of the different formations from the
vicinity of Tarpon Springs to St. Petersburg is given in figure 4.
The following discussion of the formations of Pinellas County
does not include the Ocala limestone which, although it underlies
the county, is not important locally as a water-bearing formation be-
cause it is more than 300 feet beneath the surface and is overlain by
a productive aquifer composed of the Tampa formation and Suwan-
nee limestone, and because the water from the Ocala in Pinellas
County is more highly mineralized than the water in the overlying
formations.
OLIGOCENE SERIES
All deposits of Oligocene age in Pinellas County are referred to
the Suwannee limestone. These deposits are differentiated from
the underlying deposits of Eocene age and from the overlying de-
posits of Miocene age on the basis of lithology and fossil content.
Suwannee Limestone
In Pinellas County the Suwannee limestone is composed pre-

dominantly of a white to cream-colored, hard, generally fossiliferous
limestone. Well 5 (fig. 4), north of Tarpon Springs, penetrated 180
feet of Suwannee limestone. Although the well ended in the Su-
wannee, the formation is believed to be not much over 180 feet thick.
Cooke (1945, p. 88) reports that the Suwannee lies unconformably
on the Byram limestone or, where that is absent, on the Ocala lime-
stone and that it is unconformably overlain by the Tampa formation.
It is highly permeable and a good source of water where salt water
has not entered it. Water from the Suwannee is relatively hard.
MIOCENE SERIES
Sedimentary rocks and sediments of Miocene age in Pinellas
County cannot be differentiated on the basis of fossils because of
the scarcity of identifiable specimens. Therefore, a division of the
Miocene can be made only on the basis of lithology.
The lower part of the section of Miocene age consists of hard,
sandy limestone referred to the Tampa formation. In the southern
part of the county the Tampa is overlain by marine sands and clays
of the Hawthorn formation, also of Miocene age (see fig. 4). In

REPORT OF INVESTIGATIONS No. 12
Palm Harbor, the Tampa is overlain by sediments that appear to
have been derived from weathering of the limestone. They are re-
ferred to in this report as deposits of middle and upper Miocene age.
Tampa Formation'
The Tampa formation is generally a hard, sandy limestone,
whose color varies from white to light tan. Chert fragments are
abundant in some well cuttings. The formation contains many
molds of Gastropods and Pelecypods, and a few specimens of the
foraminifera Archais floridanus and Sorites (?) sp. The Tampa
ranges in thickness from about 100 feet in the northern part of the
county to about 150 feet in the southern part.
The Tampa formation is believed by Cooke (1945, p. 115) to lie
unconformably on the Suwannee limestone. The Hawthorn forma-
tion, according to Cooke (1945, p. 145), lies conformably on the
Tampa, and in some areas of the State the two formations are so
similar lithologically that it is difficult to differentiate them. How-
ever, according to Vernon (1951, pp. 183-186, table 14) there is an
unconformity between the two in the west-central and southwestern
parts of the Floridan peninsula.
The altitude of the top of the Tampa formation is shown in
figure 5. This map is based on the altitude of the top of the first
limestone penetrated in wells, as determined from a study of rock
cuttings from 34 wells, as reported in 75 drillers' logs, and as in-
dicated by the depth of casing in 7 wells.
Where no well cuttings or drillers' logs are available, the records
of the depths of casing in wells are a generally reliable index of
the depth to the limestone, because wells are commonly cased only
to the top of the limestone. Thus, in the area north of Pinellas Park,
where other data were lacking, the records of casings were used to
determine the altitude of the top of the formation. Table 1 shows
the generally close correlation between the various types of data
used in compiling figure 5. This table lists the wells for which all
three types of data were available. Only in wells 13 and 410 was
there any considerable discrepancy among the data.
Limestones such as those of the Tampa are formed beneath the
sea and originally have a smooth upper surface which dips gently
seaward. Later, if a different type of sediment, such as sand, is

of the U. S. Geological Survey except that Tampa formation is used in this

deposited on the limestone before it emerges from the sea, the
smooth surface is preserved, and the contact between the limestone
and sand is said to be conformable. If, on the other hand, the
younger material is deposited after the surface of the limestone has
been exposed to the atmosphere and altered by erosion, the con-
tact is irregular, and is said to be unconformable.
An inspection of figure 5 reveals that the surface of the Tampa
formation is irregular. Actually, the generalized representation
shown in the figure cannot show the numerous pinnacles and sink-
holes that are presumed to exist. As pointed out above, Vernon has
found that the Tampa formation and the Hawthorn formation are
separated by an unconformity in the west-central and southwest-
ern parts of the Florida peninsula. Thus, the irregular surface of
the Tampa in southern Pinellas County is doubtless due primarily
to erosion that preceded the deposition of the Hawthorn formation.
The irregular surface of the Tampa in the central part of the county
is probably due partly to erosion and partly to irregular weathering
of the Tampa during the formation of the middle and upper Miocene
deposits.
The limestone of the Tampa contains numerous solution chan-
nels, -which provide a large storage capacity anid readily transmit
water to wells. It comprises the upper part of the productive lime-
stone aquifer, which is the principal source of water in the county.

REPORT OF INVESTIGATIONS No. 12
The hardness of its water ranges generally between 150 and 225
ppm in those wells whose water has not been contaminated by salt-
water encroachment.
Hawthorn Formation
As shown in figure 3, the Hawthorn formation underlies the
peninsula south of Clearwater. It ranges from a fairly hard gray
sandstone to sandy gray clay, and is calcareous in places. Irregu-
larly distributed through it are small grains of black and brownish
phosphate and angular fragments of chert. The formation ranges
in thickness from about 50 feet in the vicinity of Clearwater to 80
or 90 feet at the southern end of the county. It is overlain by sands
and shelly sands of Pliocene(?) and Pleistocene age.
The Hawthorn contains beds of sand which yield water to do-
mestic wells, but as a whole it is a relatively poor producer of water
because the sands are discontinuous and have a low permeability.
No analysis of water from the Hawthorn formation was made as a
part of this investigation, but it appears probable that the water
would be less hard than that from the underlying limestone forma-
tions.
The clays of the Hawthorn formation, together with those in
the deposits of middle and late Miocene age, confine the artesian
water in the limestone, retarding or preventing vertical movement
of water to or from the limestone.
Middle and Upper Miocene Deposits
The Tampa formation in the central part of the county, from
Clearwater to Palm Harbor, is overlain by deposits consisting pre-
dominantly of blue to gray clay, fine-grained sandstone, and
weathered lumps of limestone. Occurring irregularly in the deposits
are fragments of chert and cavities containing sand that probably
washed down from the Pliocene(?) and Pleistocene deposits above.
The thickness of these deposits is generally less than 50 feet.
The age of these deposits is uncertain because of the absence
of fossils. However, studies of well cuttings indicate that near their
contact with the Hawthorn formation the lower part may inter-
finger with the Hawthorn, whereas the upper part apparently
overlies the Hawthorn. Thus, these deposits are probably in part
contemporaneous with the Hawthorn formation and in part younger
15
FLORIDA GEOLOGICAL SURVEY
than the Hawthorn. They are probably equivalent to deposits re.
ferred by Vernon (1951, pp. 180 and 189) to the Alachua formation
in Citrus and Levy counties.
The large percentage of clay in these deposits would probably
prevent them from yielding even small supplies of water. However,
they constitute a competent confining bed for the water in the
underlying limestones.
PLIOCENE(?) AND PLEISTOCENE SERIES
The surface deposits in Pinellas County consist of sands and
shelly sands ranging in thickness from a few feet to more than
50 feet. North of Oakhurst and north and west of Largo they con-
sist predominantly of fine to coarse sand. Southeast of Largo and
east of Oakhurst they consist principally of calcareous sandstone.
These deposits unconformably overlie the deposits of Miocene age.
The age of the surface deposits is not definitely known. Cooke
(1945, p. 224) referred the sand and shell deposits in the southern
part of the county to the Caloosahatchee formation of Pliocene age.
On the other hand, Vernon2 believes all the deposits in Pinellas
County above those of Miocene age were deposited during the
Pleistocene.
The Pliocene(?) and Pleistocene deposits are not generally an
important source of water in those parts of the county where water
of satisfactory quality is available from the limestone, although
they yield a few small domestic supplies throughout the county.
Where salt water has moved into the limestone formations many
domestic supplies are obtained from these deposits. However, the
water from these deposits is likely to contain appreciable amounts
of salt in some of the coastal areas, particularly around the southern
end of the county. Water from these deposits is likely to be cor-
rosive and to contain objectionable amounts of iron.
GROUND WATER
OCCURRENCE
Ground water is the subsurface water that is in the zone of
saturation-the zone in which all pore spaces are completely filled
with water. The zone of saturation is the reservoir from which
all water from wells and springs is derived. The water in the zone
2Personal communication.
REPORT OF INVESTIGATIONS No. 12
of saturation is derived from rain and snow that falls on the earth's
surface. Not all the precipitation on the earth's surface soaks into
the ground, however; part of it is returned to the atmosphere by
evaporation, and part of it enters streams, lakes, and other open
bodies of water and becomes surface water. Of the part that does
filter into the earth some is lost by transpiration of plants, and
some reaches the zone of saturation. Upon reaching the zone of
saturation, the water is available to supply wells and springs and
is thereafter referred to as ground water. Water between the zone
of saturation and the land surface is subsurface water but is not
called ground water.
The amount of rainfall that enters the ground to become ground
water depends upon many factors. Among these are the slope of
the land on which the rain falls, the vegetal cover, the intensity of
the rain, the climate and the character of the surface material
through which the water must percolate to reach the zone of
saturation. After water reaches the zone of saturation it begins
to move laterally under the influence of gravity toward a place of
discharge, such as a spring, a surface stream, or the ocean.
The ground water thus moving toward a point of discharge may
be under either water-table (nonartesian) conditions or artesian
conditions. Where it only partly fills a permeable formation, its
surface is free to rise and fall and it is said to be under water-table
conditions. Where it completely fills a permeable bed that is over-
lain by a relatively impermeable bed, it is confined and its surface
is not free to rise and fall. Water thus confined is said to be under
"artesian" conditions. Technically, the term "artesian" is applied
to ground water that is confined under sufficient pressure to rise
above the top of the permeable bed that contains it, but not
necessarily above the land surface.
A formation in the zone of saturation that is permeable enough
to transmit water in a usable quantity to wells and springs is
called an "aquifer" or water-bearing formation. Areas in which
water from the surface percolates downward to the zone of satura-
tion are called "recharge areas." Ordinarily, water-table aquifers
are exposed at the land surface almost everywhere and hence re-
ceive recharge over most of their expanse. On the other hand,
artesian aquifers can receive recharge only in areas in which their
confining beds are discontinuous or absent.
Ground water in Florida occurs under both artesian and water-
table conditions. The principal artesian aquifer consists of several
17
FLORIDA GEOLOGICAL SURVEY
limestone formations of Eocene, Oligocene, and Miocene age thft
act more or less as a single hydrologic unit. Stringfield (1936, pp.
125-132, 146) described the aquifer and mapped the piezometric
surface of artesian water in 1933 and 1934. Later, Parker (1946)
proposed the name "Floridan aquifer" as a collective term for the
water-bearing limestone formations. In a large part of Florida
the water in this aquifer is confined under pressure by relatively
impermeable beds of Miocene age. The collective term "Floridan
aquiclude" has been applied to these confining beds by Parker (1951,
pp. 819-820).
Ground water in Pinellas County occurs under both water-table
and artesian conditions. The water in the surficial sand deposits
throughout the county and the water in the Tampa formation and
Suwannee limestone in the area lying north of Palm Harbor and
west of Lake Tarpon is under water-table conditions. South of
Palm Harbor and east of Lake Tarpon the water in the limestone
aquifer is under artesian conditions.
The height to which water in an artesian well will rise above
a given datum is called the artesian "pressure head." The pressure
head at any place in the artesian system is controlled in part by
the head in the area in which the aquifer is recharged, which in
turn is determined by the amount of replenishment that reaches
the aquifer from rainfall. Systematic observations of the artesian
head or, as the case may be, of the water table are an important
part of any investigation of ground water.
WATER LEVEL RECORDS
Measurements of water levels have been made in many wells in
Pinellas County. The measurements are recorded in table 5, to-
gether with the dates on which they were made. They provide in-
formation on the altitude and seasonal variations of the artesian
head in the county.
Variations in water level from one time to another are principally
the result of such factors as rainfall, pumping, and tides. In order
to obtain continuous records of the changes in the artesian head,
eight wells in Pinellas County were equipped with automatic water-
stage recorders. Hydrographs for seven of the wells, prepared from
the records of these recording gages, are shown in figures 6 and 7.
The first recorder was installed on well 272 at Clearwater in No-
vember 1945 and was kept in operation until June 1949, when it
became necessary for the city to place the well in service as a

municipal-supply well. Fortunately, however, the recorder on
well 246, only eight-tenths of a mile north of well 272, was placed
in operation shortly after the one on well 272. The records for the
other wells in the county were begun in the last half of 1947.
As may be seen from figures 6 and 7 the water-stage recorders
were removed from wells 269 and 337 when the owners installed
pumps. The record for well 337 ended in April 1950, and that for
well 269 ended in December 1952.
Long-time records from water-stage recording instruments are
very useful in studies of salt-water encroachment, as they indicate
the extent to which water levels may be declining because of such
factors as heavy pumping and artificial drainage through canals.
As the artesian head controls the extent to which sea water may
move into the formation, a progressive decline, however slow,
would indicate that the encroachment problem is likely to become
more critical. The hydrographs of the wells equipped with automa-
tic water-stage recorders (figs. 6 and 7) show a slight decline of
water levels from the beginning of each record to the spring of 1950.
The decline was probably due in part to a relatively low rainfall dur-
ing 1948 and 1949, although some of the decline may have been due
to withdrawal. During the summer and fall of 1950 the water levels
rose to the highest point on record in all wells except well 13. A
new high probably would have been recorded in well 13 also, had the
gage not become temporarily inoperative early in September.
After the high levels of September 1950 the water levels in
all wells declined slowly until May 1951, after which they declined
rapidly in all wells except well 13. This rapid decline was doubtless
due to a heavier use of water for irrigation during May and June
when the rainfall was below normal. About the middle of June
the water levels began to recover, probably as a result of decreased
pumping. During the rainy season, from July through September,
they were about the same as at the beginning of the year, although
they were still 1 to 3 feet lower than in September 1950. They re-
mained relatively stable until April 1952 when they began to decline
rapidly once more. By the middle of May they had reached the
lowest points on record in wells 246 and 269, in Clearwater, and in
well 561, east of Pinellas Park. These low water levels were probably
due to heavy pumping during April and May, which months were
exceptionally dry-the rainfall at Clearwater and Tarpon Springs
totaling less than 2 inches during the 2-month period.

FLUCTUATIONS OF WATER LEVELS
The water levels in artesian wells fluctuate almost continuously.
Some of the varied causes of the fluctuations observed in Pinellas
County are rainfall, pumping, ocean tides, variations in barometric
pressure, earthquakes, and moving railroad trains. The fluctuations
range from almost inperceptible movements to changes of several
feet. The changes of water level produced by rainfall and pumping
are the largest of all the fluctuations and are the most important
because they affect the amount of water in the aquifer and the
extent to which sea water will encroach.
Fluctuations caused by tides, changes in barometric pressure,
earthquakes, and trains are usually less than a foot in amplitude
and of short duration, and are significant only in that they reveal
the elastic properties of the aquifer. Generally these fluctuations,
except those due to tides, occur only in wells that end in artesian
aquifers. Tidal fluctuations occur along coasts in both artesian and
water-table aquifers.
Fluctuations Caused by Rainfall
Fluctuations caused by rainfall are especially significant because
they indicate the extent to which the water in the aquifer is re-
plenished. Well 337, near Coachman, is in an area in which the
artesian limestone aquifer receives recharge from rain. Thus, the
water level in this well may be expected to respond relatively
rapidly and strongly to rains. A hydrograph giving the complete
record for well 337 is shown in figure 6, but the time scale of this
hydrograph is so condensed that the response of the water level
to individual rains is not apparent. However, the response is obvious
in figure 8, which gives the record for 1948 on an expanded time
scale. As the water level in the well is lowered during certain
periods of the year by intermittent pumping from other wells in
the vicinity, the daily highest and lowest water levels are given so
that the effect of pumping may be observed and differentiated
from the effect of rainfall.
A study of figure 8 indicates that rain at Clearwater is generally
followed within a few days by a rise in the water level in well 337.
At times, however, a rain at Clearwater is not followed by a rise
in the water level, and at other times the water level rises ap-
preciably when no rain at Clearwater is recorded. This occasional
lack of correlation between the water level and the rainfall is
doubtless due principally to differences between the rainfall at

Clearwater and that at Coachman. Such differences in rainfall
within short distances are common in Florida.
The hydrographs of those wells in the county on which recording
gages are maintained and the rainfall at the stations nearest the
wells, given in figures 6 and 7, indicate the manner in which the
water levels vary seasonally and from year to year in relation to
rainfall. The relationship is somewhat obscured by the fact that
periods of relatively heavy pumping accompany periods of little
or no rainfall. Thus, the decline of water levels during droughts is
only in part a direct result of the lack of rainfall, and the recovery
of water levels during rainy periods is only in part a direct result
of the rains. Where relatively heavy pumping of water for irrigation
accompanies droughts, as it does in Pinellas County, a differentia-
tion between respective effects of rainfall and of pumping on water
levels can be made only after much investigation and study, if at
all. The available information does not permit a differentiation
of the two effects in figures 6 and 7.
Fluctuations Caused by Pumping
When water is pumped from a well that penetrates an artesian
aquifer the water level in the well and the artesian head in the
surrounding area are lowered. The decline of the artesian head
is greatest at the pumped well and it decreases as the distance

that caused them. The relatively long downward trends in the
11:00 a.m., April 6, are typical of the drawdown curves caused by
steady pumping from one or more wells. Had the drawdown curve
on April 6 not been interrupted by a cessation of pumping from
some of the wells, it would have continued downward, gradually ap-
proaching the horizonttal, as indicated by the dashed line B-B'
representing a logarithmic extension of the curve. However, as
23
FLORIDA GEOLOGICAL SURVEY
the demand for water decreased during the evening, the pumping
became intermittent, and the water level recovered and declined in
a complicated fashion. The rise of the water level during the night
of April 5 and the morning of April 6 has the form of a typical
recovery curve, such as that which follows the cessation of pumping
from one or more wells. Such curves have very nearly the form
of a drawdown curve on an inverted scale. If there had been no
further pumping, the recovery during the morning of April 6 would
have continued at a diminishing rate, as indicated by the dashed
line A-A', until the water became stabilized at some higher level.
The relationship between the hydrograph shown in figure 9
and the rainfall at Clearwater demonstrates the manner in which
rainfall acts as a secondary influence on water levels through its
effect on the use of water and, hence, on the rate of pumping. The
rainfall recorded by the U. S. Weather Bureau at Clearwater was
0.45 inch on April 5, 0.11 inch on April 6, 0.26 inch on April 11, and
0.90 inch on April 12. No rainfall was recorded during the period
April 7 to 10. A heavier use of water during the period April 8 to 11
is indicated by the fact that the water level in well 269 was more
strongly affected by pumping during that period. It appears prob-
able that the heavier pumping of water beginning April 8 was a
result of the use of water for lawn sprinkling during the brief
drought. The fact that the heavier pumping extended into April
11, when 0.26 inch of rain was recorded, might be explained by the
possibility that the rain fell during the late afternoon, or by the
fact that April 11 fell on Monday, which is washday for many
homes.
Wherever there is pumping, water levels react in much the same
way as they do in well 269. The resultant effect is a general lower-
ing of the water levels which is most pronounced where heavily
pumped wells are concentrated. In those areas where large quan-
tities of ground water are used for irrigation, water levels will be
lowered most during droughts, when wells are pumped most
heavily.
Fluctuations Caused by Tides
The water levels in many wells near the coast fluctuate in
response to ocean tides. These fluctuations are due to one of two
causes: (1) where the aquifer is exposed to the sea, to a direct
marginal transfer of water between the ocean and the ground
water, and (2) in an artesian aquifer that is exposed to the ocean

only at places more or less remote from the well, to an alternate
compression and expansion of the aquifer by the rise and fall of
the tide. Tidal fluctuations are apparent on the records of the
automatic recording gages on wells 246 and 272, which are respec-
tively 0.2 and 0.3 mile from Clearwater Harbor. The maximum
recorded tidal fluctuation in these wells is about half a foot. Figure
10, which is a tracing of the record of an automatic recorder, shows
the effect of tides on the water level in well 272 during the period
August 2 to 9,1946. Short vertical lines above the line representing
the water level show the predicted times of high tide at St.
Josephs Sound (Clearwater Harbor) as given in the tide tables of
the U. S. Coast and Geodetic Survey, 1946. The maximum water
levels in the well lag half an hour or more behind the predicted
times of high tide.
Fluctuations Caused by Earthquakes and Trains
The water levels in many wells that penetrate the artesian aqui-
fers in Florida fluctuate when earthquake waves pass the wells.
Such waves cause very rapid alternate expansion and contraction
of the acquifer, which force the water level in the well to rise and
fall.
25
FLORIDA GEOLOGICAL SURVEY
Fluctuations of the water level in well 272 that were caused by
the destructive Dominican Republic earthquake of August 4, 1946,
are shown in figure 10. Also shown are fluctuations caused by the
aftershock of the earthquake, which occurred on August 8, 1946.
The maximum magnitude of the earthquake fluctuation of August
4 was 0.9 foot, and the water level continued to fluctuate for about
2 hours.
Slight fluctuations caused by the passing of trains are not un-
common in artesian wells near railroad tracks (Jacob, 1939, pp. 666-
674). Such fluctuations are small and are perceptible only in wells
that are within a few hundred feet of the railroad tracks. They
are caused by a compression of the aquifer by the weight of the
train. The fluctuations in well 272, shown in figure 10, were caused
by trains passing on the Seaboard Air Line Railroad tracks about
50 feet from the well.
Fluctuations Caused by Changes in Atmospheric Pressure
Changes in atmospheric pressure cause corresponding changes
in the water level of artesian wells (Parker and Stringfield, 1950,
pp. 450-453). Fluctuations of water level due to changes in at-
mospheric pressure are often masked by greater fluctuations that
are due to other causes, but they are readily recognizable on the
charts obtained from the water-stage recording instruments on
wells 337 and 561.

similarity between the two graphs is obvious. Rises in atmos-

PIEZOMETRIC SURFACE IN FLORIDA
The height to which water will rise above sea level in wells
that penetrate the principal artesian aquifer in Florida is shown by
the contour lines in figure 12. The imaginary surface represented
by the contour lines is referred to as a "piezometric surface." The
shape of the piezometric surface indicates the direction of move-
ment of artesian water and the areas in which the aquifer is re-
plenished by water that falls as rain. Water enters the aquifer
Figure 12.-Map of Florida showing, the piezometric surface.
27
FLORIDA GEOLOGICAL SURVEY
in those areas in which the piezometric surface is high and moves
in a direction approximately perpendicular to the contour lines to
the areas in which the piezometric surface is low.
One of the most conspicuous features of the piezometric surface
in Florida, shown in figure 12, is the dome centered in Polk County,
which indicates that considerable recharge enters the artesian
aquifer in Polk and surrounding counties (Stringfield, 1936, p. 148).
The artesian aquifer is also recharged in Pasco County and parts
of Hernando and Hillsborough Counties, where the piezometric
surface has the shape of a smaller dome with a maximum altitude
of about 80 feet. As indicated by the slope of the piezometric sur-
face, the artesian water flows southwestward from the central part
of Pasco County into northeastern Pinellas County.
PIEZOMETRIC SURFACE IN PINELLAS COUNTY
The piezometric surface in Pinellas County is shown in figures
13 and 14. Figure 13 was prepared from measurements made in
June 1949 of water levels in 69 wells in the county. Figure 14 was
prepared from measurements made in May 1951 of water levels
in 57 wells in the county. As indicated by the contours in the figures,
the piezometric surface at the time of the measurements ranged
from less than 2 feet above sea level in the northwestern part of
the county to slightly more than 22 feet above sea level in the north-
eastern part of the county. In the Pinellas peninsula the piezometric
surface is highest in a small area south of Coachman, where it
stands slightly more than 16 feet above sea level.
The piezometric surface changes constantly in response to such
influences as rainfall and pumping, but its general features remain
the same. Thus it can be seen from a comparison of figures 13 and
14 that in response to differences in rainfall and pumping the
piezometric surface was appreciably lower in May 1951 than it was
in June 1949. In fact, a comparison of the water-level measure-
ments, which are included in table 5, shows that the water levels
were 0.2 foot to 4.3 feet lower in 1951 than in 1949.
Owing to the lack of a sufficient number of wells in which
water-level measurements can be made, the details of the piezo-
metric surface cannot be mapped accurately in many parts of the
county. Although nearly 1,000 wells have been drilled to the
Tampa formation in Pinellas County, water levels were accessible
for measurement in less than 75 wells, because of the way in which
28
REPORT OF INVESTIGATIONS NO. 12
turbine pumps were installed. In other parts of the State most
wells that have turbine pumps are equipped with air lines which
permit measurement of the water levels, but few wells in Pinellas
County are so equipped. Facilities for making water-level measure-
ments are especially desirable in areas affected by salt-water en-
croachment to aid in determining the extent of encroachment, which
is controlled by the height of the water table or the artesian head.
Prior to the mapping of the piezometric surface it was thought
that the artesian water in the Pinellas peninsula was derived from
recharge in Pasco and Hillsborough counties (Stringfield, 1933, pp.
15-16). The more detailed mapping of the piezometric surface
(fig. 13 and 14) has revealed, however, that in addition to the
artesian water moving into the county from adjoining counties
the aquifer receives recharge locally by rains. Most of the local re-
charge apparently occurs where the piezometric surface has a
ridgelike shape in the area north and south of Coachman. The
rate of recharge is probably greatest in the area centered about a
mile south of Coachman where the piezometric surface has the
shape of an elongated dome.
It is not possible to determine the extent of the recharge area
from a study of the piezometric surfaces. In fact, it appears prob-
able that some recharge enters the aquifer by slow percolation
through the confining bed wherever the water table stands ap-
preciably higher than the piezometric surface. Recharge doubtless
enters the aquifer also wherever the confining bed is discontinuous
or absent, as, for example, through the sinkholes in the eastern part
of Dunedin. A study of the piezometric surfaces has revealed,
however, that the artesian water in all the county south of a line
through Palm Harbor and Oldsmar is derived wholly from local
rainfall. The water in the aquifer in the county north of Palm
Harbor and Oldsmar is derived in part from local recharge and in
part from recharge in Pasco and Hillsborough counties.
In the area north of Palm Harbor and west of Lake Tarpon the
piezometric surface is low and has very little slope. In this area
the aquifei contains large solution channels and is so permeable
that the water moves very freely through the aquifer on its way to
the Gulf. Wall Springs, the submarine spring offshore at Crystal
Beach, and the spring in Spring Bayou at Tarpon Springs are three
known points of discharge from the aquifer in this area. East of
Palm Harbor is an embayment in the piezometric surface, which
may be caused by heavy pumping from the large number of irri-

gation wells in that area, or possibly by a relatively free movement
of water through subterranean solution channels, or by both. An-
other small embayment occurs south of Palm Harbor on the 1951
piezometric surface, but not on the 1949 piezometric surface. This
feature is probably due to heavy pumping in that area for irrigation
at the time the water-level measurements were made in 1951. The
largest embayment in the piezometric surface, which occurs around
the north end of Old Tampa Bay, is doubtless caused by natural dis-
charge of water into the bay. Over all the southern part of Pinellas
County, south 'of Walsingham, the piezometric surface is relatively
flat and has a maximum height of less than 10 feet. The lowness
of the piezometric surface in this area doubtless is a result of the
lack of local recharge.
AREA OF ARTESIAN FLOW
Wherever the piezometric surface stands higher than the land
surface, wells will flow under natural artesian pressure. The stip-
pled areas in figure 13 represent the areas in Pinellas County in
which artesian wells will flow. The areas of flow include: a narrow
band, generally less than a mile in width, that extends from a
point about 2 miles south of Clearwater around the southern end
of the peninsula to a point on the east coast about 2 miles south
of Coachman; an area about a mile wide that extends up the valleys
of Long Bayou and Cross Bayou east of Oakhurst and Largo; a
small area slightly more than a mile wide at the north end of Old
Tampa Bay about 2 miles west of Oldsmar; and a small area at the
south end of Lake Tarpon which extends a short distance up Booker
Creek. The areas of artesian flow decrease in size as the artesian
head declines. Many wells that are reported to, have flowed con-
tinuously when first drilled 10 or more years ago now flow only
when there is a high tide in the Gulf or in wet periods when there
is little or no use.
SALT-WATER ENCROACHMENT
The encroachment of sea water into fresh ground water has, in
the last few decades, become a major problem in many coastal areas
in the Nation. Such encroachment may occur wherever the pressure
head in an aquifer that is exposed to the sea is lowered excessively
by pumping or by artificial surface drainage. The problem first
became prominent in Pinellas County between 1920 and 1930 when
the early municipal-supply wells of St. Petersburg began to yield
FLORIDA GEOLOGICAL SURVEY
salty water. Subsequently many irrigation wells, other public-
supply wells, and domestic wells began to yield salty water.
Relationship Between Fresh Water and Sea Water
The relationship between fresh ground water and sea water in
coastal areas was investigated by Badon Ghyben in 1887 and, ap-
parently independently, by Baurat Herzberg about 1900 (Brown,
1925, p. 16). These investigators found that in small islands and
in certain coastal areas that are composed of permeable material,
fresh ground water, because of its lower density "floats" upon the
sea water. As with any other floating body, part of it is above
sea level and part of it is below sea level, the ratio of the density
of fresh water to that of sea water being such that the volume of
fresh water below sea level is much larger than that above sea level.
Thus, as postulated by Ghyben and Herzberg, the depth to salt
water is a function of the height of the water table above sea
level and of the density of sea water. The relationship may be
expressed by the formula
h t
g-1
where h is the depth of fresh water below sea level, t is the height
of the water table (or piezometric surface) above sea level, and

g is the specific gravity of sea water. For practical purposes the
specific gravity of fresh water is assumed to be 1.000.
The formula may be explained by reference to figure 15 which
represents the occurrence of fresh water and sea water in a small
island, or narrow peninsula, composed of permeable material, in
conjunction with a large imaginary U-tube having one leg beneath
the land and one leg in the sea. It is apparent that in such a U-tube
the column of fresh water in one leg, which has a height of h + t,
will balance the column of sea water in the other leg, which has
a height h. The ratio of the height of the column of fresh water
to that of the column of sea water will be equal to the ratio of the
specific gravity of sea water to the specific gravity of fresh water.
That is,
h+t g.
h 1
This equation reduces to the formula given above.
The specific gravity of sea water varies from one place to another
but is generally considered to be 1.025. If this value is substituted
in the formula given above then h = 40t which indicates that the
depth of fresh water below sea level is 40 times the height of the
water table above sea level. In other words, for each foot that the
water table stands above sea level the fresh water will extend be-
low sea level an additional 40 feet.
The Ghyben-Herzberg principle is tacitly based on the assump-
tion that the body of fresh water floats on sea water in static
equilibrium. In fact, however, such a body of ground water is never
static but, instead, is in constant motion, receiving replenishment
from rain and discharging into the sea. It has been shown by
Muskat (1937, p. 289) and Hubbert (1940, p. 924) that the dynamic
condition under which ground water occurs tends to vitiate the
Ghyben-Herzberg principle wherever the slope of the water table
is comparatively steep, as in the immediate vicinity of discharge
along a shoreline or a pumped well. In general, however, the slope
of the water table is so gentle that the condition of hydrostatic equi-
librium assumed by Ghyben and Herzberg is closely approximated.
The contact between fresh and sea water is not a well-defined
boundary such that on one side is found fresh water and on the other
side sea water. Instead there is a zone of intermixture, commonly
called the "zone of diffusion," which separates the overlying fresh
water from the underlying sea water. Within the zone of diffusion
33
FLORIDA GEOLOGICAL SURVEY
the salinity of the water ranges from that of uncontaminated ground
water to undiluted sea water. The zone of diffusion arises principally
from the vacillation of the fresh water-sea water contact in response
to fluctuations of the water level and the rise and fall of the tide.
As indicated by Brown (1925, p. 36), European investigators found
the zone of diffusion ranges in thickness from 60 to 100 feet under
normal conditions. Investigations in the Miami area have shown the
width of the zone of diffusion there to be 60 feet (Parker, 1945, p.
539).
Salt-Water Encroachment in Pinellas County
About 91 percent of the dissolved solids content of sea water
consists of chloride salts. Thus, determinations of the chloride con-
tent of ground water are generally a reliable indication of the extent
to which normally fresh ground water has become contaminated
with sea water. More than 500 determinations of chloride content
of water from wells in Pinellas County have been made. It has been
found that, in general, ground water which has not been contam-
inated by sea water contains less than 50 ppm of chloride, whereas
that which is contaminated contains up to 1,000 ppm and more. To
most persons, water having a chloride content of 350 to 500 ppm
has a perceptibly salty taste.
The determinations of chloride content are listed in table 5. The
generalized results of these determinations are shown in figure 16.
As can be seen from this figure, there are four areas in the county
in which a considerable number of wells yield water with a chloride,
content in excess of 50 ppm, and in which salt-water encroachment
has likely occurred. These areas include: a small area south and
east of Palm Harbor that extends from Clearwater Harbor inland
for a distance of 2 to 3 miles most of the area in the vicinity of
Indian Rocks, Walsingham, and Oakhurst; a narrow band about
a mile wide along the southeastern coast; and a small area at the
north end of Old Tampa Bay about 2 miles west of Oldsmar.
Although salt water has apparently encroached into the areas
described above, it can be seen from figure 16 that there are a few
wells in each of the areas that yield water with a chloride content
of less than 50 ppm. Conversely, there are a few wells in nearly
every other part of the county that yield water with a chloride con-
tent of more than 50 ppm. These irregularities are due in part to
the fact that the wells sampled varied considerably in depth, and
in part to the fact that some had been pumped extensively prior
34
REPORT OF INVESTIGATIONS NO. 12
to sampling. As a rule the deeper wells may be expected to yield
water with a higher chloride content than the shallower ones and
a given well will yield water with a higher chloride content after
prolonged pumping.
One example of how the chloride content differs between wells
of different depths may be cited. On January 28, 1947, well 458,
which is 108 feet deep, had a chloride content of 25 ppm, whereas
on the same day well 459, which is no more than about 0.1 mile
from well 458 and is 289 feet deep, had a chloride content of 400
ppm.
An example of how the chloride content increases when a well
is pumped is shown in table 2, which gives the results of tests
made on well 420 by V. C. Jamison of the University of Florida
Citrus Experiment Station at Lake Alfred.

The well had been idle for at least several days prior to June 7.
After it had been pumped for 15 minutes the chloride content was
only 129 ppm, but after 3 hours of pumping the chloride content had
risen to 2,984 ppm. The chloride content did not change significantly
after the first 3 hours of pumping. Although the yield of the well
is unknown, it was probably more than 100 gallons a minute.
According to the Ghyben-Herzberg principle, the contact be-
tween fresh water and sea water along a section from Clearwater
Harbor to Coopers Bayou would be as shown in figure 17. Several
assumptions were made in drawing this section ard it approximates
the actual contact so far as these assumptions are correct. One as-

sumption is that the limestone aquifer is isotropic (equally per-
meable in all directions) so that water may move through it ver-
tically as well as horizontally. There appears to be no doubt that
the limestone contains some layers that are less permeable than
others and hence that water will move less freely vertically than
horizontally. It appears likely, however, that there is enough
interchange of water between the upper and lower parts of the
aquifer to enable the fresh water-sea water contact to adjust, in
time, to the piezometric surface. Moreover, because there are
hundreds of wells in the county which have open holes through
several hundred feet of limestone, there is probably a relatively
free exchange of water between the different permeable zones
in some parts of the county.
Another assumption is that the fresh water-sea water contact
is in equilibrium with the piezometric surface. The contact probably
rises during times of heavy withdrawal and is depressed by fresh
water entering the aquifer during the wet season. However, be-
cause the contact can rise only as the fresh water immediately above
it is withdrawn from storage and replaced by sea water, a process
referred to by Wentworth (1942, pp. 683-693) as "change in bottom
storage," there is necessarily a lag between the time the fresh-
water head is lowered and the time the contact has reached the
new point of equilibrium. In fact, the recent experience of well
owners in some of the coastal areas in Pinellas County, especially in
the area from Clearwater to Indian Rocks, where wells have become
contaminated with salt water without any detectable decline in
artesian head, seems to indicate that the head declined to about
its present level prior to 1947, when water-level observations were
begun, and that the contact has not yet reached equilibrium with
the lowered position of the piezometric surface.
A study of figure 16 reveals that wells on the upland area in the
vicinity of St. Petersburg (see fig. 2) yield water with a chloride
content of less than 50 ppm, although numerous wells between this
area and the principal recharge area near Coachman yield water
with a chloride content of more than 50 ppm. Thus, it appears
probable that the limestone aquifer in the vicinity of the upland
area is being recharged by water percolating downward from the
water-table aquifer through the confining bed. Additional evidence
that local recharge is occurring in southern Pinellas County is
offered by the configuration of the contour lines of the piezometric
surface on figure 14.

Figure 18.-Map of northwestern Pinellas County showing locations

UNDERGROUND DRAINAGE OF LAKE TARPON
Lake Tarpon, formerly known as Lake Butler, in the northern
part of Pinellas County, is connected by an underground channel
with Spring Bayou, at Tarpon Springs (fig. 18). At irregular in-
tervals the lake drains through this underground channel into
Spring Bayou, and between drainings the salt water from Spring
Bayou moves through the channel, contaminating the lake water.
An explanation of how the draining occurs has been suggested by
0. E. Meinzer and V. T. Stringfield and described by H. H. Cooper,
Jr. (personal communication) as follows:
38
REPORT OF INVESTIGATIONS No. 12
"During the intervals between drainings the channel evidently
becomes blocked in such a way as to retain the water in the lake and
allow the stage to build up. Ultimately the stage builds up so high
that the block is overcome, and the lake drains. The nature and me-
chanics of this block have been a subject of interesting speculation.
"A plausible explanation of the phenomenon has been suggested
by Mr. Meinzer. He points out that the underground channel, in
conjunction with the vents in the lake and bayou, forms a crude
U-tube, in which a column of the relatively dense sea water in Spring
Bayou balances a higher column of fresh water in the lake. So long
as the system is in balance, the contact between fresh water and sea
water is in the lake vent at a depth which depends on the lake stage, the
tide in the bayou, and the relative densities of the two waters. As the
differential in head increases with a rising stage or a falling tide, this
contact is depressed. When the differential in head is great enough
to depress the contact to the bottom of the U, any further increase
throws the system out of balance, the sea water flushes out of the
channel, and the lake drains.
"The lake will cease to drain when a new static balance between
the two columns of water is established at a lower stage. Probably
the cessation of flow occurs during a rising tide in the bayou, and
subsequently, near high tide, sea water moves back through the
channel into the lake vent once more to complete the cycle.
"The reason that the lake stage at which flushing begins varies
from one time to another is apparent when one considers that this
critical stage is dependent on two variables: one is the tide level
in the bayou, and the other is the density of the lake water. The
density of the lake water varies with the extent to which it is mixed
with sea water by the constant agitation of the tide. At times the
concentration of salts in the lake water, especially in the vicinity
of the sink, may be so high as to allow the lake to flush under a con-
siderably lower head differential than if the water were altogether
fresh.
"The ratio of the specific gravity of sea water to that of fresh water
is about 1.025 to 1.000, or 41 to 40. Thus, a column of sea water 40 feet
in height will balance a column of fresh water 41 feet in height. Ap-
plied to the problem at hand, this relationship indicates that for each
foot of lake stage above the bayou tide level there will be a depth of
40 feet below the bayou level to the contact between the two waters,
providing the lake water is fresh. If the lowest section of the U-system
were, for example, 120 feet below sea level, the highest possible head
differential that could occur without flushing would be about 3.0 feet.
Differentials in head of more than 3.0 feet would indicate that the
lowest section of the underground channel is more than 120 feet below
sea level. When additional studies have been made, it may become
possible to predict with a fair degree of accuracy when flushings will
occur. Investigations of the specific gravity of water at various depths
in the lake sink immediately prior to the flushings are needed. Also
needed are studies of the differentials in head with consideration of the
time required for tidal fluctuations to be transmitted through the
system."
An investigation of the underground drainage of the lake was
undertaken by the U. S. Geological Survey. As a part of the in-
vestigation, automatic recording gages were installed on well 13
at Tarpon Springs and on Lake Tarpon. Charts from the recorder
on Lake Tarpon show, that the lake drained 27 times from July
1945 to November 1949. The stage of the lake at the start of the
drainings has ranged from 2.5 to 5.5 feet above mean sea level
39

and at the cessation of the drainings, from 1.2 to 3.1 feet above
mean sea level.
The hydrograph for well 13 (see fig. 19) shows that the water
level in the area west of Lake Tarpon fluctuates in response to the
changes in lake level. In fact, the fluctuations of water level in
well 13 and of Lake Tarpon are almost identical. Thus, as shown
in figure 19, unusual fluctuations associated with the draining of
Lake Tarpon occurred in both the well and the lake in August and
October of 1948 and in August, September, October, and November
of 1949.
The lake drains through a sinkhole having a maximum mea-
sured depth of 115 feet just off the northwest shore of the lake
(fig. 18). After entering the sinkhole the water moves through
an underground channel or channels and emerges through a vent
in the bottom of Spring Bayou.

Figure 20 shows the variations in the chloride content, and thus
indicates the variations in density, of the water in the lake sink
during one drainage cycle. The lake stopped draining on March 30
or 31, 1949, probably during a high tide in the bayou, after which
relatively salty water flushed into the lake sink, reaching almost
to the surface of the lake by April 7. From April 7 to June 30,
while the lake was relatively low (fig. 19), salty water remained
in the lake sink, its vertical position changing, partly as a result of
tides in Spring Bayou. As the lake rose, beginning in July (fig. 19),
the salt water in the lake sink was depressed and diluted (fig. 20)
until, sometime between August 4 and August 11, the balance
between the fresh water and salt water was upset and the lake
started to drain. Draining of the lake is accompanied by a partial
draining of the aquifer in the area west of the lake, as indicated
by the hydrograph of well 13 in figure 19. A plot of the chloride
content of water at the surface and at the bottom of the sinkhole
in Lake Tarpon from early 1947 to April 1948 is shown in figure 19.
A comparison of this plot with the mean daily stage of the lake
during 1947 shows that during the period from May to July, after
the lake had drained, its level remained relatively low and salty
water was present in the bottom of the sinkhole. In August, as the
stage of the lake began to rise, the salty water in the sinkhole was
depressed until it could no longer be reached for sampling.
QUALITY OF WATER
Chemical analyses of 10 samples of water from selected wells in
the county, made by the Quality of Water Branch of the U. S.
Geological Survey, are shown in table 3. The relative mineralization
of the different samples is best observed by comparing the amount
of dissolved solids. In general, such a comparison shows that min-
eralization increases with depth and with distance from the re-
charge area. Thus, the wells at Clearwater, Dunedin, Largo, and
Safety Harbor, all of which are relatively near the Coachman re-
charge area, contained less than 300 ppm of dissolved solids, where-
as the wells at Bay Pines, Oldsmar, and Pinellas Park, which are
much farther from points of recharge, contained more than 900
ppm.
Nitrate is derived from the decomposition of organic material,
and a relatively high content of this constituent generally indicates
the presence of local recharge. No analyses were made of the
nitrate content of water from wells near the center of the Coachman
42
REPORT OF INVESTIGATIONS No, 12
recharge area. However, the nitrate content of well 167 at Dunedin
and well 640 at St. Petersburg was 6.0 and 6.5 ppm respectively,
indicating local recharge near both these wells. As pointed out in
a previous section, the possibility of local recharge at St. Peters-
burg is indicated also by the fact that wells in the upland part of
the city yield water having a lower chloride content than wells in
the area between St. Petersburg and the principal recharge area
in the vicinity of Coachman.
Hardness affects the suitability of water for certain uses.
Among the most noticeable effects are the increased quantities of
soap needed to form a lather and the scale formed in vessels when
the water is heated. Most hardness is due to the presence
of calcium and magnesium, although iron, aluminum, and other
substances, which are generally present only in negligible quantities,
contribute to it. Water having a hardness of less than 50 ppm is
generally considered soft. Hardness of 50 to 150 ppm does not
seriously interfere with the use of water for most purposes, al-
though the quantity of soap required to form a lather is noticeably
larger. Water having a hardness of more than 150 ppm is rated as
hard and is commonly softened when used for household and other
domestic uses. Each sample analyzed for this report had a hardness
of more than 175 ppm. Three samples, those from Bay Pines, Olds-
mar, and Pinellas Park, each had a hardness of more than 495 ppm.
Studies in some areas of the United States have shown that
children who drink water that contains about 1 ppm of fluoride
have fewer cavities in their teeth than children who drink water
that contains much less than 1 ppm (Dean, 1943, pp. 1161-1183).
However, fluoride in concentrations more than 1.5 ppm tend to
cause mottling of the enamel of the permanent teeth of young
children who habitually use the water. In view of this, it is sig-
nificant that the samples from well 167 at Dunedin and well 25 at
Tarpon Springs did not contain measurable amounts of fluoride and
the others contained only 0.1 to 0.6 ppm.
Iron differs from most of the other chemical constituents
normally found in ground water in that concentrations as low as
0.1 ppm may impart objectionable characteristics such as a fer-
ruginous taste and the staining of plumbing fixtures. Three of the
samples from Pinellas County, those from Oldsmar, Safety Harbor,
and St. Petersburg, contained more than 0.1 ppm of iron. However,
it appears possible that the relatively high iron contents of 0.81
ppm in well 212A at Oldsmar and 1.64 ppm in well 640 at St. Peters-

burg are due in part to contamination by the casing and other iron
pipes through which the water passed and thus do not give a true
indication of the iron content of water in the aquifer.
The significance of the chloride content of water is discussed in
the section entitled "Salt-Water Encroachment."
USE OF WATER
Nearly all water for public, industrial, agricultural, and domestic
uses in Pinellas County is obtained from wells. The Pinellas County
Water System, which obtains part of its supply from McKay Creek,
is the only public system using surface water as a source of supply
at the present time, but it, also, obtains part of its supply from
ground water.
Wells tapping the artesian aquifer range in diameter from 3
to 12 inches and range in depth from about 50 feet to as much as
300 feet. The yield of deep wells varies with the permeability of
the limestone penetrated, the amount of open hole, and the diameter,
but wells having diameters of 8 inches and more generally yield
several hundred gallons a minute. Shallow wells are generally
developed by driving 11/ inch casing, equipped with a well point,
to a depth of from 25 to 50 feet. A few shallow domestic supplies
are obtained from dug wells having diameters of 24 inches or more.
The Florida State Board of Health lists 13 public water systems
in Pinellas County, all of which, except the St. Petersburg system,
obtain water from wells in the county. St. Petersburg obtains its
water from wells in Hillsborough County. The average output of
each system in 1947 (Florida State Board of Health, 1948, pp.
20-21) is given in table 4.

FLORIDA GEOLOGICAL SURVEY
The consumption of water in Pinellas County is increasing so
fast that any figures given on consumption are obsolete before
publication. For example, the average daily output of the Clear-
water system increased from 1.5 million gallons in 1947 to 3.2 mil-
lion gallons in 1951, and that of the Pinellas County Water System
increased from 0.65 to 1.5 million gallons over the same period.
One of the most important items to be considered in a study of
the ground-water resources of an area is the total consumption of
ground water. However, because there are hundreds of domestic
and irrigation wells scattered throughout Pinellas County on which
no pumping records are kept, it has not been feasible to derive a
consumption figure that is much more than a calculated guess.
About the best estimate that can be made is that the consumption
of water in Pinellas County was 13 to 14 million gallons a day in
1951.
St. Petersburg Water Supply
Although the investigation leading to this report was concerned
primarily with the ground-water resources of Pinellas County,
the report would not be complete without a discussion of the water
supply of St. Petersburg, which is now obtained from 12 wells near
Cosme, in northwestern Hillsborough County. The St. Petersburg
supply serves approximately half the population of Pinellas County.
All the wells draw water from the limestone aquifer. The water
in the aquifer in the Cosme area enters the limestone formations
through the recharge area in Pasco County and northern Hills-
borough County.
Measurements made in 1930 of the water levels in the Cosme
wells indicate that the piezometric surface stood between 36 and
43 feet above sea level prior to the time the wells were put into
operation (see table 5). The current average daily pumping of
about 12 million gallons has doubtless created a cone of depression
around the well field, but the depth and extent of the cone have not
been mapped. However, a record of the water level since October
1930 in Hillsborough County well 13 (see fig. 21), about 4 miles
east of the nearest supply well at Cosme, indicates that the piezo-
metric surface has not been lowered appreciably at that distance
from the well field. When it is considered that in other places in
Florida, as in northeastern Florida (Cooper and Warren, 1945, pp.
263-282), the piezometric surface has been lowered substantially
by heavy pumping over distances much greater than 4 miles with-
out any serious consequences, tle record of the water level in Hills-

borough County well 13 appears to indicate that the ground-water
resources in the Cosme area are not being unduly affected by pump-
ing. In fact, the available information indicates that the ground
water resources in the region north and east of Cosme have the
capacity to yield several times the amount of water that is now
being pumped, provided new wells are dispersed over an area of
sufficient breadth to avoid excessive drawdowns.
SUMMARY AND CONCLUSIONS
The results of the investigation of ground-water resources in
Pinellas County may be summarized as follows:
1. The principal source of ground water in Pinellas County is
an aquifer composed of the Tampa formation and Suwannee lime-
stone. In the northern part of the county the top of this aquifer is
10 to 50 feet beneath the surface. Toward the south its depth in-
creases until in the vicinity of St. Petersburg it is more than 125
feet beneath the surface. In the area north of Palm Harbor and
west of Lake Tarpon the water in the aquifer is under water-table
conditions. In the remainder of the county the water is under ar-
tesian conditions.
2. West and south of Lake Tarpon the water in the aquifer is
derived wholly from local rainfall. North of Palm Harbor the
aquifer is covered only with permeable material and hence receives
recharge from rainfall readily. South of Palm Harbor the aquifer
is overlain by material of low permeability but nevertheless receives
substantial quantities of recharge through sinkholes in the area
around Coachman; the area of recharge possibly includes the
vicinity of Dunedin. Recharge in this area is indicated by the fact
that the piezometric surface stands high-as much as 16 feet above
sea level about a mile south of Coachman. Lesser quantities of
recharge doubtless enter the artesian aquifer wherever the water
table stands very high above the piezometric surface, as, for ex-
ample, in the upland area around St. Petersburg.
3. Salt-water encroachment is the most critical ground-water
problem confronting the county. Areas already affected by en-
croachment include: (1) most of the area between Palm Harbor
and the southwest shore of Lake Tarpon; (2) most of the area
between Indian Rocks, Walsingham, and Oakhurst; (3) an area
about a mile wide along the southeastern coast of the county; and
48
REPORT OF INVESTIGATIONS NO. 12
(4) a small area at the north end of Old Tampa Bay about 2 miles
west of Oldsmar. The chloride content of the water from wells in
these areas ranges from less than 50 to as much as several thousand
parts per million.
The quantity of water that may be safely withdrawn from the
aquifer at a given place depends on the water-transmitting capacity
of the aquifer and on the height of the piezometric surface. Where
the piezometric surface stands highest, more water can be with-
drawn without causing salt water to move into the wells. Wherever
the piezometric surface is lowered, water is removed from storage,
and the water so removed is replaced in part by water from the sea.
4. In the long run, salt-water encroachment can be controlled
only by limiting the total draft to a rate at which an adequate fresh-
water head will be maintained. Where feasible, the safe draft at a
given place and from a given group of wells might be increased by
artificially recharging the aquifer-that is, by injecting surplus
surface water into the aquifer through wells. To be effective, how-
ever, the artificial recharge would have to be introduced in the
immediate vicinity of the pumped wells. If, for example, the aquifer
were artificially recharged in the vicinity of Coachman, no ap-
preciable beneficial results would accrue to the wells in the vicinity
of Walsingham, but the safe draft at Coachman might be increased.
At some places, where geologic conditions are favorable, artificial
recharge would be most effective if applied immediately adjacent to
the coast, where it would build up a ground-water "ridge" to act
as a barrier to the inland advance of sea water (Laverty and others,
1951). This approach to the problem would be effective, however,
only if the aquifer were underlain by a watertight formation, for
otherwise the salt water could move upward from the deeper forma-
tion, thereby bypassing the barrier. The scanty information on
the geology of Pinellas County indicates that there is no watertight
formation underlying the aquifer and, hence, that an attempt to
halt the advance of sea water by creating a ground-water ridge
along the coast probably would not be successful.
Artificial recharge can put a stop to an encroachment of salt
water only if the rate of recharge exceeds the rate of withdrawal.
So long as the draft of ground water in Pinellas County continues
to increase the problem of salt-water encroachment will grow more
serious. An encroachment of salt water is especially lamentable
because its effects are long lasting. Having once established inroads
49
FLORIDA GEOLOGICAL SURVEY
into the aquifer, the salty water will rinse out only very slowly,
leaving traces for many years and perhaps for generations after
remedial measures are undertaken.
The investigation leading to this report was restricted largely
to a study of the existing wells in the county, because funds for
drilling test wells and observation wells were not available. As
most of the wells are finished with open holes that extend through
more than 100 feet of limestone and thus draw from more than one
water-bearing zone, several aspects of the problem of salt-water
encroachment could not be investigated. Among these are (1) the
relation between the height of the piezometric surface and the
depth below sea level of the fresh water-sea water contact, (2) the
rate of advance of the contact in the areas already affected by
salt-water encroachment, and (3) the possibility of differences in
pressure heads between various water-bearing zones.
The relation between the height of the piezometric surface and
the depth to the salt-water contact must be studied before the
problem of salt-water encroachment can be adequately understood.
Figure 17 was drawn on the basis of the Ghyben-Herzberg principle,
described in the section titled "Salt-Water Encroachment," to show
where the contact would be if it were in hydrostatic equilibrium
with the piezometric surface. The position of the contact as shown
in figure 17 may differ from the true position because the permea-
bility of the aquifer in a vertical direction is doubtless much less
than the permeability in a horizontal direction, and because vertical
movements of the contact that accompany changes in the height
of the piezometric surface are delayed by changes in "bottom
storage." On the other hand, if the Ghyben-Herzberg principle is
found to apply approximately, the effects of pumping at a given
place can be predicted fairly well.
Studies are needed also to determine the rate at which salt-
water encroachment is occurring. Water samples for chloride
analyses have been collected from selected wells several times
since 1948 in an effort to determine the rate of encroachment. How-
ever, the results of these analyses have not been consistent, because
each well draws from several water-bearing zones so that the
samples are mixtures of water from several depths, and possibly
because intermittent pumping of the wells by the owners causes
the chloride content to vary inconsistently from one sampling to
another. Where the rate of encroachment can be determined it
may be possible to predict when the wells will become contaminated.
50
REPORT OF INVESTIGATIONS No. 12
A program designed to determine how closely the Ghyben-
Herzberg principle applies and to observe the advance of the salt-
water contact would consist of establishing a series of observation
stations approximately 1 mile apart across the county from Clear-
water to Tampa Bay. Each station should consist of three or four
small-diameter wells drilled and cased to different depths in the
aquifer. The deepest of the wells would end in the zone of diffusion
between fresh water and salt water, the shallowest would end near
the top of the aquifer, and the other one or two would end at in-
tervening depths. Such a system of wells would provide a means of
extracting water samples and measuring pressure heads at isolated
depths in the aquifer, an operation that is not possible with the
existing, open-hole wells. Tests of chloride content of water from
the wells of each station would indicate how the salt-water contact
advances and retreats, and measurements of the water levels would
provide a record of the changes in pressure head that cause the
contact to advance and retreat. Similar stations could well be
established in each of the areas affected by salt-water encroachment
to provide accurate information on how the extent of the encroach-
ment may increase or decrease.
Further analyses of the chloride content of water from many
wells throughout the county, at least once a year, would provide
much needed additional information on the extent of salt-water
encroachment. As of February 1, 1953, five recorders were in
operation (on wells 13, 77, 166, 246, and 561), three having been
discontinued because the owners of the wells rightfully elected to
restore the wells to their own service. As the height of the piezo-
metric surface controls the extent to which salt water will encroach,
it is especially desirable that records of water levels such as are
obtained through the use of automatic recording gages be continued
indefinitely on at least five or six wells strategically located over
the county.

LETTER OF TRANSMITTAL liorida geololical Survey Callahassee June 15, 1954 Mr. Charlie Bevis, Supervisor Florida State Board of Conservation Tallahassee, Florida Dear Mr. Bevis: One of the first cities in Florida to experience a failure of a well field through salt water intrusion was the city of St. Petersburg. This large population center is located on a narrow peninsula and the heavy draft of water for municipal and other rapidly developing enterprises, such as tourist and beach attractions, permanent homes, and large agricultural and other water-using businesses encouraged the county commissioners and officials of the larger cities of the county to inventory its water supply. This water resource study, undertaken by the United States and Florida Geological Surveys at the request of the citizens of Pinellas County is being published as Report of Investigations No. 12. It is a pleasure to record that a large source of potable water was discovered during the investigation, lying wholly within the boundaries of Pinellas County, and an adequate supply is available for an increased development of the economy of the area. Respectfully, Herman Gunter, Director iii

GROUND-WATER RESOURCES of PINELLAS COUNTY, FLORIDA By Ralph C. Heath and Peter C. Smith ABSTRACT Pinellas County comprises a land area of 290 square miles along the west coast of Florida, and forms a peninsula between Old Tampa Bay and the Gulf of Mexico. It is underlain by a series of limestone formations having a total thickness of several thousand feet. The upper several hundred feet of the limestone consists of the Suwannee limestone of late Oligocene age and the Tampa formation of early Miocene age. South of Palm Harbor these limestones are overlain by clays and sandy clays of middle and late Miocene age. A veneer of Pliocene(?) and Pleistocene sands and shelly sands, ranging in thickness from several feet to more than 50 feet, overlies the clays and sandy clays in the area south of Palm Harbor and overlies.the Tampa formation' in the area north of Palm Harbor. The Tampa and Suwannee limestones constitute the principal source of water in the county. Water in these formations occurs under water-table conditions in most of the area north of Palm Harbor and west of Lake Tarpon, and under artesian conditions in the area south of Palm Harbor. Where the water is under watertable conditions the formations are recharged locally by rain. In the area south of Palm Harbor, where the clays and sandy clays confine the water in the limestones under pressure, water enters the formations wherever the confining beds are discontinuous or absent, but principally through sinkholes in the vicinity of Coachman. The artesian water in the Tampa formation and Suwannee limestone in the area north of Old Tampa Bay and east of Lake Tarpon is derived principally from recharge that enters the limestones in northern Hillsborough County and southern Pasco County. 'In the area north of Palm Harbor and west of Lake Tarpon, the water table is relatively low, ranging from about 2 feet to about 6 feet above sea level. Over the rest of the county, where the water 'The stratigraphic nomenclature ,of this report conforms to the nomenclature of the Florida Geological Survey. It conforms also to the nomenclature of the U. S. Geological Survey except that Tampa formation is used in this report instead of Tampa limestone.

2 FLORIDA GEOLOGICAL SURVEY in the limestones is under artesian pressure, the piezometric surface ranges from about 2 feet above sea level in some areas near the coast to more than 22 feet in the northeastern part of the county. The problem of salt-water encroachment first became prominent in Pinellas County between 1920 and 1930 when the early municipalsupply wells of St. Petersburg began to yield salty water. Areas on both coasts of the county have been affected by the encroachment. These include: (1) a small area that extends in a northeasterly direction from the coast south of Palm Harbor almost to Lake Tarpon; (2) most of the area between Indian Rocks and Long Bayou; (3) an area along the southeastern coast of the county beginning in the vicinity of Lake Maggiore and extending northward for more than 15 miles; and (4) a small area at the north end of Old Tampa Bay about 2 miles west of Oldsmar. The chloride content of the water from many of the deep wells in the areas of salt-water encroachment is more than 500 parts per million, whereas the chloride content of uncontaminated ground water in the county is generally less than 50 ppm. Uncontaminated ground water generally contains less than 300 ppm of dissolved solids and has a total hardness of less than 250 ppm. INTRODUCTION The difficulty of locating and preserving adequate potable water supplies is a problem confronting many of Florida's coastal communities. In some areas the problem is one of finding satisfactory water in sufficient quantity to supply the needs of the community; in others, the problem is one of protecting supplies already developed against an encroachment of salt water. The presence of naturally salty ground water in some of the water-bearing formations in Brevard, Sarasota, Charlotte, Lee, and other counties of the State makes the finding of satisfactory ground-water supplies difficult. In Pinellas County, however, the problem is primarily one of preventing the encroachment of salt water into the water-bearing formations. Salt-water encroachment began first in the southern part of the county in the early twenties. By 1930 it had so seriously affected the St. Petersburg supply that a new well field was developed for the city at Cosme, more than 20 miles north of the city, in Hills-

REPORT OF INVESTIGATIONS No. 12 3 borough County. Since 1930 salt water has continued to move into the water-bearing formations as a result of a gradual increase in the withdrawal from wells. Among the other public water supplies in the county that have increased in salinity are those of Clearwater, Tarpon Springs, Pinellas Park, and the Pinellas County Water System. In addition, many wells supplying water for irrigation and domestic uses have also been affected by the encroachment. PURPOSE AND SCOPE OF INVESTIGATION The investigation leading to this report was begun in 1944 by the United States Geological Survey in cooperation with the Florida Geological Survey and the Board of County Commissioners of Pinellas County. Its primary purpose was to determine the extent to which salt water had encroached into the water-bearing formations and, to evaluate the factors governing encroachment. An investigation of the surface-water resources of the county also was begun in 1944 by the Surface Water Branch of the U. S. Geological Survey. The field work of the ground-water investigation consisted of: 1. The collection of information on the location, the depth and diameter, and other pertinent facts on the existing wells in the county. 2. Analyses of the chloride content of water from all flowing wells and from most of the wells equipped with pumps. 3. Repeated analyses of the chloride content of water from selected wells. 4. Measurements of the water level in all open wells that could be found. 5. The collection and geologic study of rock cuttings from 34 wells. 6. The installation of eight automatic water-stage recorders. PERSONNEL AND ACKNOWLEDGMENTS Most of the field work of the investigation was done by P. C. Smith, of the U. S. Geological Survey, whose death in March 1949
PAGE 10
4 FLORIDA GEOLOGICAL SURVEY prevented his writing the report. Earlier field work was done by A. G. Unklesbay and T. C. Wiggins, also of the Federal Survey. R. C. Heath collected the data on the piezometric surfaces, the terraces, and the geology and prepared the report. The investigation was made under the immediate supervision of H. H. Cooper, Jr., District Engineer, and under the general supervision of A. N. Sayre, Chief of the Ground Water Branch, U. S. Geological Survey, and Herman Gunter, Director of the Florida Geological Survey. Helpful assistance was given throughout the investigation by W. A. McMullen, who was then County Engineer of Pinellas County. A. R. Swartz, of the U. S. Department of Agriculture, Soil Conservation Service, placed his office facilities at the disposal of the authors during the investigation, and F. S. Mann, also of the Soil Conservation Service, assisted in making water-level measurements. A. O. Dunlap and other well drillers saved cuttings and gave information on numerous wells. Also, information on wells was given by many public officials and private individuals. PREVIOUS INVESTIGATIONS The water resources and geology of Pinellas County have been treated briefly in previous reports of the Florida Geological Survey and the U. S. Geological Survey. A report by Matson and Sanford (1913, pp. 319-325) describes the geology and ground water of Hillsborough County, which at that time included the area that is now Pinellas County. A report by Sellards and Gunter (1913, pp. 258-262) contains a generalized map of the area of artesian flow and describes the water-bearing formations. Chemical analyses of 23 samples of water from Pinellas County are listed in a report by Collins and Howard (1928, p. 224). A recent report on the chemical character of Florida waters (Black and Brown, 1951, pp. 91-93) contains 81 analyses of water samples from Pinellas County. A report by Stringfield (1933, pp. 13-17) gives a general discussion of the occurrence of ground water in the county and calls attention to the problems that need investigation. A map of the piezometric surface of the principal artesian aquifers in the Florida peninsula and a discussion of recharge and discharge areas are included in a report by Stringfield (1936). The geologic formations that crop out in Pinellas County have been described by Cooke (1945, pp. 131, 192, 224). A report by Ferguson and others (1947, p. 137) describes two of the largest springs in the county and gives chemical analyses of their waters.

REPORT OF INVESTIGATIONS No. 12 5 GEOGRAPHY LOCATION AND AREA Pinellas County is approximately in the center of the west coast of Florida (see fig. 1) and includes the peninsula that separates Old Tampa Bay from the Gulf of Mexico. It has a total of 439 square miles, of which only 290 square miles, or 185,600 acres, is land. The county has a coast line of 128 miles, a length of about 40 miles, and an average width of about 7 miles. CLIMATE The climate of the county is subtropical. The average annual rainfall at Tarpon Springs during the 51-year period beginning in 1892, according to the records of the U. S. Weather Bureau, was 51.20 inches. The average annual rainfall at St. Petersburg over the 32-year period beginning in 1915 was 53.24 inches.

6 FLORIDA GEOLOGICAL SURVEY average annual rainfall over a long period of years is about the same in the northern part as it is in the southern part of the county. However, in any particular year the amount falling on one part may differ from that falling on another part by as much as 15 inches, or more. In 1941, for instance, Tarpon Springs had 62.46 inches of rainfall, whereas St. Petersburg had only 45.77 inches. The months of heaviest rainfall are June through September. The mean temperature in the county is 71.7° F. TOPOGRAPHY The topography of Pinellas County may be divided into three types: hilly uplands, characteristic of the area from Oakhurst to Palm Harbor; a flat upland, around St. Petersburg; and level lowlands, characteristic of the area north and east of Pinellas Park. All of these subdivisions lie within "The Terraced Coastal Lowlands" (see Vernon, 1951, p. 16.). The principal upland area, here referred to as the "Pinellas ridge," is an area ranging from 3 to 4 miles in width, bordering the Gulf of Mexico from the vicinity of Oakhurst to the vicinity of Palm Harbor. It consists of gently rolling hills formed by the erosion of small streams, and of sinkholes formed by collapse of the surface formations into limestone caverns. Altitudes on the ridge range from about 25 feet to as much as 100 feet above sea level. However, the summits of most of the hills are between 80 and 95 feet above sea level, their concordance indicating that the Pinellas ridge may once have been a continuous, relatively level upland. The highest altitude in Pinellas County, as recorded on the topographic maps of the U. S. Corps of Engineers, is 97 feet, on State Highway 580 about 4 miles east of Dunedin. The maximum relief on the ridge is in Sec. 5, T. 28 S., R. 16 E., near the southwest shore of Lake Tarpon, where the altitude changes more than 40 feet in less than a tenth of a mile. North of Pinellas ridge, and separated from it, is a line of small hills, extending around the north end of Lake Tarpon, whose summits range in altitude from about 20 to about 60 feet. Although these hills are not a part of the ridge, they give the area in which they occur a topography similar to that of the ridge. The upland in the vicinity of St. Petersburg has low relief, the maximum altitude being about 50 feet. This area is roughly circular and has a diameter of about 5 miles. Surrounding the upland areas are areas of low-lying level land and swamps, which range in altitude from sea level to about 25 feet. These level lowlands are best exemplified and have the greatest

REPORT OF INVESTIGATIONS No. 12 7 areal extent north and west of St. Petersburg and south and east of Lake Tarpon. TERRACES During Pleistocene time the sea stood above and below its present level, submerging greater and lesser portions of the land according to its height. Whenever it remained relatively stationary for a long period, waves and currents washing back and forth across the sea floor formed an essentially level surface, called a "terrace." Upon the retreat of the sea to a lower level each terrace emerged as a level plain having a slight seaward dip. The landward margin of such a terrace is the abandoned shoreline, which is generally marked by a low scarp. Discussions of the Pleistocene history and the terraces in Florida are included in a report by Cooke (1945, pp. 245-312) and Vernon (1951, pp. 19-32). Three of these terraces, the Pamlico, Penholoway, and Wicomico, have been recognized by the senior author in Pinellas County. The Pamlico terrace, whose shoreline is approximately 25 feet above present sea level, is well preserved in Pinellas County. The Penholoway may be associated with a scarp that is present at several places in the county between 60 and 70 feet above sea level. The Wicomico terrace, built when the sea stood approximately 100 feet above its present level, is represented by the highest surfaces of the Pinellas ridge. The terraces are not readily recognizable on the topographic maps of the county because the maps have 20-foot contour intervals and hence do not show sufficient detail. In order to identify and delineate the terraces, several traverses across the county were made with an aneroid barometer. However, the topographic maps were used to delineate them in the relatively inaccessible areas where traverses were not made. The boundaries of the terraces are shown in figure 2. When the sea stood 100 feet higher than it does today, during Wicomico time, the Pinellas ridge was a shoal about 40 miles west of the nearest land, which consisted of a large island located in what is now the relatively high lake region of central Florida. Much of the shoal, particularly in the area northeast of Dunedin, was so near sea level that some parts of it may have emerged during low tide. During the formation of the Penholoway terrace, which is believed by Cooke (1945, p. 17) to have occurred during the Sanga-

REPORT OF INVESTIGATIONS No. 12 9 mon stage (interglacial), about 200,000 years ago, the Pinellas ridge was a chain of islands about 35 miles west of the mainland. Remnants of a scarp that was formed during that time are, among other places, at the following locations: about three-fourths of a mile east of Palm Harbor on State Road 580; about 3 miles east of Dunedin and also about 5 miles east of Dunedin; near the south side of Largo on U. S. Highway 19; and about a quarter of a mile north of Walsingham on U. S. Highway 19. Cooke (1945, p. 292) recognized the Talbot terrace having a scarp based at 42 feet. The senior author recognized no such terrace in Pinellas County but included in the Pamlico terrace deposits which Cooke might have considered to be Talbot. However, at several places in the county the base of the Pamlico terrace is at an altitude of 42 feet. The most notable example is the segment of the scarp on State Road 580 about half a mile west of Tampa Bay. There, the land surface rises from 40 to 52 feet above sea level in less than a tenth of a mile. Another is near the intersection of 38th Avenue West and 44th Street North in St. Petersburg, where the surface rises from 42 to 53 feet above sea level. The Pamlico is the best preserved and therefore the most easily recognizable terrace in Pinellas County. Its landward margin, which coincides with the shoreline of the Pamlico sea, occurs at the base of a low scarp that is well preserved at many places in the county. The scarp is well preserved, for example, along Clearwater Harbor in the vicinity of Clearwater, where it is rarely more than several hundred feet inland from the present shore, and also along the west side of Old Tampa Bay. However, it is not generally as well preserved on the bay as on the gulf. The line of hills (see fig. 2) that extends from the Pinellas ridge along the west and north shores of Lake Tarpon may have been formed, as a bar (Leverett, 1931, p. 21) or a spit, of material transported from the Pinellas ridge by an ocean current flowing in a northerly direction. The change in trend of the islands from north to east around the north end of Lake Tarpon was probably caused either by local currents, such as would accompany eastward-moving storms, or by a change in direction of the dominant'ocean current during the formation of the Pamlico terrace. The building of sand dunes has increased the altitude of some of these islands by as much as 15 to 40 feet above the level of the sea at that time.
PAGE 16
10 FLORIDA GEOLOGICAL SURVEY DRAINAGE The northern part of the county is drained underground by solution channels in the Tampa formation, and by the Anclote River. The Pinellas ridge is drained by a series of short creeks on both the east and west coasts. Sinkholes and lakes also receive some of the surface drainage of the ridge, particularly in the area around Coachman, where part of the rainfall percolates downward through sinkholes into the underlying formations. The southern part of the peninsula is drained by Long Bayou and Cross Bayou and their short natural tributaries, and by the network of canals that have been dug to drain the previously swampy areas in the vicinity of Pinellas Park. GEOLOGY The geologic formations that are exposed in Pinellas County range from deposits of early Miocene age (the Tampa formation) to undifferentiated deposits of Pliocene(?) and Pleistocene age. Those below the Pliocene(?) and Pleistocene are exposed in a series of belts across the county (fig. 3). The boundaries of the formations as shown on figure 3 are generalized, but probably represent the true boundaries rather closely. Information on which the geologic map was drawn was obtained from 34 well logs and from a study of several outcrops of the formation. A geologic cross section showing the vertical extent of the different formations from the vicinity of Tarpon Springs to St. Petersburg is given in figure 4. The following discussion of the formations of Pinellas County does not include the Ocala limestone which, although it underlies the county, is not important locally as a water-bearing formation because it is more than 300 feet beneath the surface and is overlain by a productive aquifer composed of the Tampa formation and Suwannee limestone, and because the water from the Ocala in Pinellas County is more highly mineralized than the water in the overlying formations. OLIGOCENE SERIES All deposits of Oligocene age in Pinellas County are referred to the Suwannee limestone. These deposits are differentiated from the underlying deposits of Eocene age and from the overlying deposits of Miocene age on the basis of lithology and fossil content. Suwannee Limestone In Pinellas County the Suwannee limestone is composed pre-

Although the well ended in the Suwannee, the formation is believed to be not much over 180 feet thick. Cooke (1945, p. 88) reports that the Suwannee lies unconformably on the Byram limestone or, where that is absent, on the Ocala limestone and that it is unconformably overlain by the Tampa formation. It is highly permeable and a good source of water where salt water has not entered it. Water from the Suwannee is relatively hard. MIOCENE SERIES Sedimentary rocks and sediments of Miocene age in Pinellas County cannot be differentiated on the basis of fossils because of the scarcity of identifiable specimens. Therefore, a division of the Miocene can be made only on the basis of lithology. The lower part of the section of Miocene age consists of hard, sandy limestone referred to the Tampa formation. In the southern part of the county the Tampa is overlain by marine sands and clays of the Hawthorn formation, also of Miocene age (see fig. 4).

REPORT OF INVESTIGATIONS No. 12 13 Palm Harbor, the Tampa is overlain by sediments that appear to have been derived from weathering of the limestone. They are referred to in this report as deposits of middle and upper Miocene age. Tampa Formation' The Tampa formation is generally a hard, sandy limestone, whose color varies from white to light tan. Chert fragments are abundant in some well cuttings. The formation contains many molds of Gastropods and Pelecypods, and a few specimens of the foraminifera Archais floridanus and Sorites (?) sp. The Tampa ranges in thickness from about 100 feet in the northern part of the county to about 150 feet in the southern part. The Tampa formation is believed by Cooke (1945, p. 115) to lie unconformably on the Suwannee limestone. The Hawthorn formation, according to Cooke (1945, p. 145), lies conformably on the Tampa, and in some areas of the State the two formations are so similar lithologically that it is difficult to differentiate them. However, according to Vernon (1951, pp. 183-186, table 14) there is an unconformity between the two in the west-central and southwestern parts of the Floridan peninsula. The altitude of the top of the Tampa formation is shown in figure 5. This map is based on the altitude of the top of the first limestone penetrated in wells, as determined from a study of rock cuttings from 34 wells, as reported in 75 drillers' logs, and as indicated by the depth of casing in 7 wells. Where no well cuttings or drillers' logs are available, the records of the depths of casing in wells are a generally reliable index of the depth to the limestone, because wells are commonly cased only to the top of the limestone. Thus, in the area north of Pinellas Park, where other data were lacking, the records of casings were used to determine the altitude of the top of the formation. Table 1 shows the generally close correlation between the various types of data used in compiling figure 5. This table lists the wells for which all three types of data were available. Only in wells 13 and 410 was there any considerable discrepancy among the data. Limestones such as those of the Tampa are formed beneath the sea and originally have a smooth .upper surface which dips gently seaward. Later, if a different type of sediment, such as sand, is 'The stratigraphic nomenclature of this report conforms to the nomenclature of the Florida Geological Survey. It conforms also to the nomenclature of the U. S. Geological Survey except that Tampa formation is used in this report instead,of Tampa limestone.

If, on the other hand, the younger material is deposited after the surface of the limestone has been exposed to the atmosphere and altered by erosion, the contact is irregular, and is said to be unconformable. An inspection of figure 5 reveals that the surface of the Tampa formation is irregular. Actually, the generalized representation shown in the figure cannot show the numerous pinnacles and sinkholes that are presumed to exist. As pointed out above, Vernon has found that the Tampa formation and the Hawthorn formation are separated by an unconformity in the west-central and southwestern parts of the Florida peninsula. Thus, the irregular surface of the Tampa in southern Pinellas County is doubtless due primarily to erosion that preceded the deposition of the Hawthorn formation. The irregular surface of the Tampa in the central part of the county is probably due partly to erosion and partly to irregular weathering of the Tampa during the formation of the middle and upper Miocene deposits. The limestone of the Tampa contains numerous solution channels, -which provide a large storage capacity anid readily transmit water to wells. It comprises the upper part of the productive limestone aquifer, which is the principal source of water in the county. A1

REPORT OF INVESTIGATIONS No. 12 15 The hardness of its water ranges generally between 150 and 225 ppm in those wells whose water has not been contaminated by saltwater encroachment. Hawthorn Formation As shown in figure 3, the Hawthorn formation underlies the peninsula south of Clearwater. It ranges from a fairly hard gray sandstone to sandy gray clay, and is calcareous in places. Irregularly distributed through it are small grains of black and brownish phosphate and angular fragments of chert. The formation ranges in thickness from about 50 feet in the vicinity of Clearwater to 80 or 90 feet at the southern end of the county. It is overlain by sands and shelly sands of Pliocene(?) and Pleistocene age. The Hawthorn contains beds of sand which yield water to domestic wells, but as a whole it is a relatively poor producer of water because the sands are discontinuous and have a low permeability. No analysis of water from the Hawthorn formation was made as a part of this investigation, but it appears probable that the water would be less hard than that from the underlying limestone formations. The clays of the Hawthorn formation, together with those in the deposits of middle and late Miocene age, confine the artesian water in the limestone, retarding or preventing vertical movement of water to or from the limestone. Middle and Upper Miocene Deposits The Tampa formation in the central part of the county, from Clearwater to Palm Harbor, is overlain by deposits consisting predominantly of blue to gray clay, fine-grained sandstone, and weathered lumps of limestone. Occurring irregularly in the deposits are fragments of chert and cavities containing sand that probably washed down from the Pliocene (?) and Pleistocene deposits above. The thickness of these deposits is generally less than 50 feet. The age of these deposits is uncertain because of the absence of fossils. However, studies of well cuttings indicate that near their contact with the Hawthorn formation the lower part may interfinger with the Hawthorn, whereas the upper part apparently overlies the Hawthorn. Thus, these deposits are probably in part contAemporaneous with the Hawthorn formation and in part younger C-
PAGE 25
16 FLORIDA GEOLOGICAL SURVEY than the Hawthorn. They are probably equivalent to deposits re, ferred by Vernon (1951, pp. 180 and 189) to the Alachua formation in Citrus and Levy counties. The large percentage of clay in these deposits would probably prevent them from yielding even small supplies of water. However, they constitute a competent confining bed for the water in the underlying limestones. PLIOCENE(?) AND PLEISTOCENE SERIES The surface deposits in Pinellas County consist of sands and shelly sands ranging in thickness from a few feet to more than 50 feet. North of Oakhurst and north and west of Largo they consist predominantly of fine to coarse sand. Southeast of Largo and east of Oakhurst they consist principally of calcareous sandstone. These deposits unconformably overlie the deposits of Miocene age. The age of the surface deposits is not definitely known. Cooke (1945, p. 224) referred the sand and shell deposits in the southern part of the county to the Caloosahatchee formation of Pliocene age. On the other hand, Vernon2 believes all the deposits in Pinellas County above those of Miocene age were deposited during the Pleistocene. The Pliocene (?) and Pleistocene deposits are not generally an important source of water in those parts of the county where water of satisfactory quality is available from the limestone, although they yield a few small domestic supplies throughout the county. Where salt water has moved into the limestone formations many domestic supplies are obtained from these deposits. However, the water from these deposits is likely to contain appreciable amounts of salt in some of the coastal areas, particularly around the southern end of the county. Water from these deposits is likely to be corrosive and to contain objectionable amounts of iron. GROUND WATER OCCURRENCE Ground water is the subsurface water that is in the zone of saturation-the zone in which all pore spaces are completely filled with water. The zone of saturation is the reservoir from which all water from wells and springs is derived. The water in the zone 2Personal communication.
PAGE 26
REPORT OF INVESTIGATIONS No. 12 17 of saturation is derived from rain and snow that falls on the earth's surface. Not all the precipitation on the earth's surface soaks into the ground, however; part of it is returned to the atmosphere by evaporation, and part of it enters streams, lakes, and other open bodies of water and becomes surface water. Of the part that does filter into the earth some is lost by transpiration of plants, and some reaches the zone of saturation. Upon reaching the zone of saturation, the water is available to supply wells and springs and is thereafter referred to as ground water. Water between the zone of saturation and the land surface is subsurface water but is not called ground water. The amount of rainfall that enters the ground to become ground water depends upon many factors. Among these are the slope of the land on which the rain falls, the vegetal cover, the intensity of the rain, the climate and the character of the surface material through which the water must percolate to reach the zone of saturation. After water reaches the zone of saturation it begins to move laterally under the influence of gravity toward a place of discharge, such as a spring, a surface stream, or the ocean. The ground water thus moving toward a point of discharge may be under either water-table (nonartesian) conditions or artesian conditions. Where it only partly fills a permeable formation, its surface is free to rise and fall and it is said to be under water-table conditions. Where it completely fills a permeable bed that is overlain by a relatively impermeable bed, it is confined and its surface is not free to rise and fall. Water thus confined is said to be under "artesian~" conditions. Technically, the term "artesian" is applied to ground water that is confined under sufficient pressure to rise above the top of the permeable bed that contains it, but not necessarily above the land surface. A formation in the zone of saturation that is permeable enough to transmit water in a usable quantity to wells and springs is called an "aquifer" or water-bearing formation. Areas in which water from the surface percolates downward to the zone of saturation are called "recharge areas." Ordinarily, water-table aquifers are exposed at the land surface almost everywhere and hence receive recharge over most of their expanse. On the other hand, artesian aquifers can receive recharge only in areas in which their confining beds are discontinuous or absent. Ground water in Florida occurs under both artesian and watertable conditions. The principal artesian aquifer consists of several C-,
PAGE 27
18 FLORIDA GEOLOGICAL SURVEY limestone formations of Eocene, Oligocene, and Miocene age that act more or less as a single hydrologic unit. Stringfield (1936, pp. 125-132, 146) described the aquifer and mapped the piezometric surface of artesian water in 1933 and 1934. Later, Parker (1946) proposed the name "Floridan aquifer" as a collective term for the water-bearing limestone formations. In a large part of Florida the water in this aquifer is confined under pressure by relatively impermeable beds of Miocene age. The collective term "Floridan aquiclude" has been applied to these confining beds by Parker (1951, pp. 819-820). Ground water in Pinellas County occurs under both water-table and artesian conditions. The water in the surficial sand deposits throughout the county and the water in the Tampa formation and Suwannee limestone in the area lying north of Palm Harbor and west of Lake Tarpon is under water-table conditions. South of Palm Harbor and east of Lake Tarpon the water in the limestone aquifer is under artesian conditions. The height to which water in an artesian well will rise above a given datum is called the artesian "pressure head." The pressure head at any place in the artesian system is controlled in part by the head in the area in which the aquifer is recharged, which in turn is determined by the amount of replenishment that reaches the aquifer from rainfall. Systematic observations of the artesian head or, as the case may be, of the water table are an important part of any investigation of ground water. WATER LEVEL RECORDS Measurements of water levels have been made in many wells in Pinellas County. The measurements are recorded in table 5, together with the dates on which they were made. They provide information on the altitude and seasonal variations of the artesian head in the county. Variations in water level from one time to another are principally the result of such factors as rainfall, pumping, and tides. In order to obtain continuous records of the changes in the artesian head, eight wells in Pinellas County were equipped with automatic waterstage recorders. Hydrographs for seven of the wells, prepared from the records of these recording gages, are shown in figures 6 and 7. The first recorder was installed on well 272 at Clearwater in November 1945 and was kept in operation until June 1949, when it became necessary for the city to place the well in service as a

Fortunately, however, the recorder on well 246, only eight-tenths of a mile north of well 272, was placed in operation shortly after the one on well 272. The records for the other wells in the county were begun in the last half of 1947. As may be seen from figures 6 and 7 the water-stage recorders were removed from wells 269 and 337 when the owners installed pumps. The record for well 337 ended in April 1950, and that for well 269 ended in December 1952. Long-time records from water-stage recording instruments are very useful in studies of salt-water encroachment, as they indicate the extent to which water levels may be declining because of such factors as heavy pumping and artificial drainage through canals. As the artesian head controls the extent to which sea water may move into the formation, a progressive decline, however slow, would indicate that the encroachment problem is likely to become more critical. The hydrographs of the wells eqg1ipped with automatic water-stage recorders (figs. 6 and 7) show a slight decline of water levels from the beginning of each record to the spring of 1950. The decline was probably due in part to a relatively low rainfall during 1948 and 1949, although some of the decline may have been due to withdrawal. During the summer and fall of 1950 the water levels rose to the highest point on record in all wells except well 13. A new high probably would have been recorded in well 13 also, had the gage not become temporarily inoperative early in September. After the high levels of September 1950 the water levels in all wells declined slowly until May 1951, after which they declined rapidly in all wells except well 13. This rapid decline was doubtless due to a heavier use of water for irrigation during May and June when the rainfall was below normal. About the middle of June the water levels began to recover, probably as a result of decreased pumping. During the rainy season, from July through September, they were about the same as at the beginning of the year, although they were still 1 to 3 feet lower than in September 1950. They remained relatively stable until April 1952 when they began to decline rapidly once more. By the middle of May they had reached the lowest points on record in wells 246 and 269, in Clearwater, and in well 561, east of Pinellas Park. These low water levels were probably due to heavy pumping during April and May, which months were exceptionally dry-the rainfall at Clearwater and Tarpon Springs totaling less than 2 inches during the 2-month period.

REPORT OF INVESTIGATIONS No. 12 21 FLUCTUATIONS OF WATER LEVELS The water levels in artesian wells fluctuate almost continuously. Some of the varied causes of the fluctuations observed in Pinellas County are rainfall, pumping, ocean tides, variations in barometric pressure, earthquakes, and moving railroad trains. The fluctuations range from almost inperceptible movements to changes of several feet. The changes of water level produced by rainfall and pumping are the largest of all the fluctuations and are the most important because they affect the amount of water in the aquifer and the extent to which sea water will encroach. Fluctuations caused by tides, changes in barometric pressure, earthquakes, and trains are usually less than a foot in amplitude and of short duration, and are significant only in that they reveal the elastic properties of the aquifer. Generally these fluctuations, except those due to tides, occur only in wells that end in artesian aquifers. Tidal fluctuations occur along coasts in both artesian and water-table aquifers. Fluctuations Caused by Rainfall Fluctuations caused by rainfall are especially significant because they indicate the extent to which the water in the aquifer is replenished. Well 337, near Coachman, is in an area in which the artesian limestone aquifer receives recharge from rain. Thus, the water level in this well may be expected to respond relatively rapidly and strongly to rains. A hydrograph giving the complete record for well 337 is shown in figure 6, but the time scale of this hydrograph is so condensed that the response of the water level to individual rains is not apparent. However, the response is obvious in figure 8, which gives the record for 1948 on an expanded time scale. As the water level in the well is lowered during certain periods of the year by intermittent pumping from other wells in the vicinity, the daily highest and lowest water levels are given so that the effect of pumping may be observed and differentiated from the effect of rainfall. A study of figure 8 indicates that rain at Clearwater is generally followed within a few days by a rise in the water level in well 337. At times, however, a rain at Clearwater is not followed by a rise in the water level, and at other times the water level rises appreciably when no rain at Clearwater is recorded. This occasional lack of correlation between the water level and the rainfall is doubtless due principally to differences between the rainfall at

Clearwater and that at Coachman. Such differences in rainfall within short distances are common in Florida. The hydrographs of those wells in the county on which recording gages are maintained and the rainfall at the stations nearest the wells, given in figures 6 and 7, indicate the manner in which the water levels vary seasonally and from year to year in relation to rainfall. The relationship is somewhat obscured by the fact that periods of relatively heavy pumping accompany periods of little or no rainfall. Thus, the decline of water levels during droughts is only in part a direct result of the lack of rainfall, and the recovery of water levels during rainy periods is only in part a direct result of the rains. Where relatively heavy pumping of water for irrigation accompanies droughts, as it does in Pinellas County, a differentiation between respective effects of rainfall and of pumping on water levels can be made only after much investigation and study, if at all. The available information does not permit a differentiation of the two effects in figures 6 and 7. Fluctuations Caused by Pumping When water is pumped from a well that penetrates an artesian aquifer the water level in the well and the artesian head in the surrounding area are lowered. The decline of the artesian head is greatest at the pumped well and it decreases as the distance

Figure 9.-Fluctuations of the water level in well 269, at Stevenson Creek, caused by pumping from Clearwater municipal-supply wells. (Figures in parentheses indicate daily rainfall, in inches, at Clearwater.) from the well increases. As pumping continues the cone of depression deepens and broadens at a gradually diminishing rate. As the cone encompasses another well the water level in that well declines. When pumping ceases the water level rises, rapidly at first, but more slowly later as it approaches the initial static level. Figure 9 shows fluctuations of the water level in well 269, at Stevenson Creek, caused by pumping from several other wells in the vicinity, including wells 253, 263, 266, 267, 270, and 271 of the Clearwater municipal supply. The nearest of these is well 270, 0.3 mile from well 269. The pumping wells nearest well 269 doubtless influence the water level more than those farther away, but, as no record is made of the times at which the individual pumps automatically start and stop, it has not been possible to identify the drawdowns and recoveries shown in the hydrographs with the wells that caused them. The relatively long downward trends in the hydrograph, such as the one between the hours of 5:00 a.m. and 11:00 a.m., April 6, are typical of the drawdown curves caused by steady pumping from one or more wells. Had the drawdown curve on April 6 not been interrupted by a cessation of pumping from some of the wells, it would have continued downward, gradually approaching the horizontal, as indicated by the dashed line B-B' representing a logarithmic extension of the curve. However, as
PAGE 34
24 FLORIDA GEOLOGICAL SURVEY the demand for water decreased during the evening, the pumping became intermittent, and the water level recovered and declined in a complicated fashion. The rise of the water level during the night of April 5 and the morning of April 6 has the form of a typical recovery curve, such as that which follows the cessation of pumping from one or more wells. Such curves have very nearly the form of a drawdown curve on an inverted scale. If there had been no further pumping, the recovery during the morning of April 6 would have continued at a diminishing rate, as indicated by the dashed line A-A', until the water became stabilized at some higher level. The relationship between the hydrograph shown in figure 9 and the rainfall at Clearwater demonstrates the manner in which rainfall acts as a secondary influence on water levels through its effect on the use of water and, hence, on the rate of pumping. The rainfall recorded by the U. S. Weather Bureau at Clearwater was 0.45 inch on April 5, 0.11 inch on April 6, 0.26 inch on April 11, and 0.90 inch on April 12. No rainfall was recorded during the period April 7 to 10. A heavier use of water during the period April 8 to 11 is indicated by the fact that the water level in well 269 was more strongly affected by pumping during that period. It appears probable that the heavier pumping of water beginning April 8 was a result of the use of water for lawn sprinkling during the brief drought. The fact that the heavier pumping extended into April 11, when 0.26 inch of rain was recorded, might be explained by the possibility that the rain fell during the late afternoon, or by the fact that April 11 fell on Monday, which is washday for many homes. Wherever there is pumping, water levels react in much the same way as they do in well 269. The resultant effect is a general lowering of the water levels which is most pronounced where heavily pumped wells are concentrated. In those areas where large quantities of ground water are used for irrigation, water levels will be lowered most during droughts, when wells are pumped most heavily. Fluctuations Caused by Tides The water levels in many wells near the coast fluctuate in response to ocean tides. These fluctuations are due to one of two causes: (1) where the aquifer is exposed to the sea, to a direct marginal transfer of water between the ocean and the ground water, and (2) in an artesian aquifer that is exposed to the ocean

Tidal fluctuations are apparent on the records of the automatic recording gages on wells 246 and 272, which are respectively 0.2 and 0.3 mile from Clearwater Harbor. The maximum recorded tidal fluctuation in these wells is about half a foot. Figure 10, which is a tracing of the record of an automatic recorder, shows the effect of tides on the water level in well 272 during the period August 2 to 9, 1946. Short vertical lines above the line representing the water level show the predicted times of high tide at St. Josephs Sound (Clearwater Harbor) as given in the tide tables of the U. S. Coast and Geodetic Survey, 1946. The maximum water levels in the well lag half an hour or more behind the predicted times of high tide. Fluctuations Caused by Earthquakes and Trains The water levels in many wells that penetrate the artesian aquifers in Florida fluctuate when earthquake waves pass the wells. Such waves cause very rapid alternate expansion and contraction of the acquifer, which force the water level in the well to rise and
PAGE 36
26 FLORIDA GEOLOGICAL SURVEY Fluctuations of the water level in well 272 that were caused by the destructive Dominican Republic earthquake of August 4,1946, are shown in figure 10. Also shown are fluctuations caused by the aftershock of the earthquake, which occurred on August 8, 1946. The maximum magnitude of the earthquake fluctuation of August 4 was 0.9 foot, and the water level continued to fluctuate for about 2 hours. Slight fluctuations caused by the passing of trains are not uncommon in artesian wells near railroad tracks (Jacob, 1939, pp. 666674). Such fluctuations are small and are perceptible only in wells that are within a few hundred feet of the railroad tracks. They are caused by a compression of the aquifer by the weight of the train. The fluctuations in well 272, shown in figure 10, were caused by trains passing on the Seaboard Air Line Railroad tracks about 50 feet from the well. Fluctuations Caused by Changes in Atmospheric Pressure Changes in atmospheric pressure cause corresponding changes in the water level of artesian wells (Parker and Stringfield, 1950, pp. 450-453). Fluctuations of water level due to changes in atmospheric pressure are often masked by greater fluctuations that are due to other causes, but they are readily recognizable on the charts obtained from the water-stage recording instruments on wells 337 and 561.

The atmospheric pressure, which is recorded on the barograph in inches of mercury, has been converted to the equivalent pressure in feet of water and plotted on an inverted scale. The similarity between the two graphs is obvious. Rises in atmospheric pressure cause corresponding declines in the water level in the well, and vice versa. PIEZOMETRIC SURFACE IN FLORIDA The height to which water will rise above sea level in wells that penetrate the principal artesian aquifer in Florida is shown by the contour lines in figure 12. The imaginary surface represented by the contour lines is referred to as a "piezometric surface."

28 FLORIDA GEOLOGICAL SURVEY in those areas in which the piezometric surface is high and moves in a direction approximately perpendicular to the contour lines to the areas in which the piezometric surface is low. One of the most conspicuous features of the piezometric surface in Florida, shown in figure 12, is the dome centered in Polk County, which indicates that considerable recharge enters the artesian aquifer in Polk and surrounding counties (Stringfield, 1936, p. 148). The artesian aquifer is also recharged in Pasco County and parts of Hernando and Hillsborough Counties, where the piezometric surface has the shape of a smaller dome with a maximum altitude of about 80 feet. As indicated by the slope of the piezometric surface, the artesian water flows southwestward from the central part of Pasco County into northeastern Pinellas County. PIEZOMETRIC SURFACE IN PINELLAS COUNTY The piezometric surface in Pinellas County is shown in figures 13 and 14. Figure 13 was prepared from measurements made in June 1949 of water levels in 69 wells in the county. Figure 14 was prepared from measurements made in May 1951 of water levels in 57 wells in the county. As indicated by the contours in the figures, the piezometric surface at the time of the measurements ranged from less than 2 feet above sea level in the northwestern part of the county to slightly more than 22 feet above sea level in the northeastern part of the county. In the Pinellas peninsula the piezometric surface is highest in a small area south of Coachman, where it stands slightly more than 16 feet above sea level. The piezometric surface changes constantly in response to such influences as rainfall and pumping, but its general features remain the same. Thus it can be seen from a comparison of figures 13 and 14 that in response to differences in rainfall and pumping the piezometric surface was appreciably lower in May 1951 than it was in June 1949. In fact, a comparison of the water-level measurements, which are included in table 5, shows that the water levels were 0.2 foot to 4.3 feet lower in 1951 than in 1949. Owing to the lack of a sufficient number of wells in which water-level measurements can be made, the details of the piezometric surface cannot be mapped accurately in many parts of the county. Although nearly 1,000 wells have been drilled to the Tampa formation in Pinellas County, water levels were accessible for measurement in less than 75 wells, because of the way in which
PAGE 39
REPORT OF INVESTIGATIONS No. 12 29 turbine pumps were installed. In other parts of the State most wells that have turbine pumps are equipped with air lines which permit measurement of the water levels, but few wells in Pinellas County are so equipped. Facilities for making water-level measurements are especially desirable in areas affected by salt-water encroachment to aid in determining the extent of encroachment, which is controlled by the height of the water table or the artesian head. Prior to the mapping of the piezometric surface it was thought that the artesian water in the Pinellas peninsula was derived from recharge in Pasco and Hillsborough counties (Stringfield, 1933, pp. 15-16). The more detailed mapping of the piezometric surface (fig. 13 and 14) has revealed, however, that in addition to the artesian water moving into the county from adjoining counties the aquifer receives recharge locally by rains. Most of the local recharge apparently occurs where the piezometric surface has a ridgelike shape in the area north and south of Coachman. The rate of recharge is probably greatest in the area centered about a mile south of Coachman where the piezometric surface has the shape of an elongated dome. It is not possible to determine the extent of the recharge area from a study of the piezometric surfaces. In fact, it appears probable that some recharge enters the aquifer by slow percolation through the confining bed wherever the water table stands appreciably higher than the piezometric surface. Recharge doubtless enters the aquifer also wherever the confining bed is discontinuous or absent, as, for example, through the sinkholes in the eastern part of Dunedin. A study of the piezometric surfaces has revealed, however, that the artesian water in all the county south of a line through Palm Harbor and Oldsmar is derived wholly from local rainfall. The water in the aquifer in the county north of Palm Harbor and Oldsmar is derived in part from local recharge and in part from recharge in Pasco and Hillsborough counties. In the area north of Palm Harbor and west of Lake Tarpon the piezometric surface is low and has very little slope. In this area the aquifei contains large solution channels and is so permeable that the water moves very freely through the aquifer on its way to the Gulf. Wall Springs, the submarine spring offshore at Crystal Beach, and the spring in Spring Bayou at Tarpon Springs are three known points of discharge from the aquifer in this area. East of Palm Harbor is an embayment in the piezometric surface, which may be caused by heavy pumping from the large number of irri-

REPORT OF INVESTIGATIONS NO. 12 31 gation wells in that area, or possibly by a relatively free movement of water through subterranean solution channels, or by both. Another small embayment occurs south of Palm Harbor on the 1951 piezometric surface, but not on the 1949 piezometric surface. This feature is probably due to heavy pumping in that area for irrigation at the time the water-level measurements were made in 1951. The largest embayment in the piezometric surface, which occurs around the north end of Old Tampa Bay, is doubtless caused by natural discharge of water into the bay. Over all the southern part of Pinellas County, south 'of Walsingham, the piezometric surface is relatively flat and has a maximum height of less than 10 feet. The lowness of the piezometric surface in this area doubtless is a result of the lack of local recharge. AREA OF ARTESIAN FLOW Wherever the piezometric surface stands higher than the land surface, wells will flow under natural artesian pressure. The stippled areas in figure 13 represent the areas in Pinellas County in which artesian wells will flow. The areas of flow include: a narrow band, generally less than a mile in width, that extends from a point about 2 miles south of Clearwater around the southern end of the peninsula to a point on the east coast about 2 miles south of Coachman; an area about -a mile wide that extends up the valleys of Long Bayou and Cross Bayou east of Oakhurst and Largo; a small area slightly more than a mile wide at the north end of Old Tampa Bay about 2 miles west of Oldsmar; and a small area at the south end of Lake Tarpon which extends a short distance up Booker Creek. The areas of artesian flow decrease in size as the artesian head declines. Many wells that are reported to, have flowed continuously when first drilled 10 or more years ago now flow only when there is a high tide in the Gulf or in wet periods when there is little or no use. SALT-WATER ENCROACHMENT The encroachment of sea water into fresh ground water has, in the last few decades, become a major problem in many coastal areas in the Nation. Such encroachment may occur wherever the pressure head in an aquifer that is exposed to the sea is lowered excessively by pumping or by artificial surface drainage. The problem first became prominent in Pinellas County between 1920 and 1930 when the early municipal-supply wells of St. Petersburg began to yield
PAGE 42
32 FLORIDA GEOLOGICAL SURVEY salty water. Subsequently many irrigation wells, other publicsupply wells, and domestic wells began to yield salty water. Relationship Between Fresh Water and Sea Water The relationship between fresh ground water and sea water in coastal areas was investigated by Badon Ghyben in 1887 and, apparently independently, by Baurat Herzberg about 1900 (Brown, 1925, p. 16). These investigators found that in small islands and in certain coastal areas that are composed of permeable material, fresh ground water, because of its lower density "floats" upon the sea water. As with any other floating body, part of it is above sea level and part of it is below sea level, the ratio of the density of fresh water to that of sea water being such that the volume of fresh water below sea level is much larger than that above sea level. Thus, as postulated by Ghyben and Herzberg, the depth to salt water is a function of the height of the water table above sea level and of the density of sea water. The relationship may be expressed by the formula h t g-1 where h is the depth of fresh water below sea level, t is the height of the water table (or piezometric surface) above sea level, and I ANO SURFAce -" ---WATER ASLEE __ MEAN SEA LEVEL 1 FRESH WATER h S4 WATER SEA WATER Figure 15.-Diagram showing the relation between fresh water and sea water beneath a narrow peninsula, according to the Ghyben-Herzberg principle.
PAGE 43
REPORT OF INVESTIGATIONS No. 12 33 g is the specific gravity of sea water. For practical purposes the specific gravity of fresh water is assumed to be 1.000. The formula may be explained by reference to figure 15 which represents the occurrence of fresh water and sea water in a small island, or narrow peninsula, composed of permeable material, in conjunction with a large imaginary U-tube having one leg beneath the land and one leg in the sea. It is apparent that in such a U-tube the column of fresh water in one leg, which has a height of h + t, will balance the column of sea water in the other leg, which has a height h. The ratio of the height of the column of fresh water to that of the column of sea water will be equal to the ratio of the specific gravity of sea water to the specific gravity of fresh water. That is, h+t g. h 1 This equation reduces to the formula given above. The specific gravity of sea water varies from one place to another but is generally considered to be 1.025. If this value is substituted in the formula given above then h = 40t which indicates that the depth of fresh water below sea level is 40 times the height of the water table above sea level. In other words, for each foot that the water table stands above sea level the fresh water will extend below sea level an additional 40 feet. The Ghyben-Herzberg principle is tacitly based on the assumption that the body of fresh water floats on sea water in static equilibrium. In fact, however, such a body of ground water is never static but, instead, is in constant motion, receiving replenishment from rain and discharging into the sea. It has been shown by Muskat (1937, p. 289) and Hubbert (1940, p. 924) that the dynamic condition under which ground water occurs tends to vitiate the Ghyben-Herzberg principle wherever the slope of the water table is comparatively steep, as in the immediate vicinity of discharge along a shoreline or a pumped well. In general, however, the slope of the water table is so gentle that the condition of hydrostatic equilibrium assumed by Ghyben and Herzberg is closely approximated. The contact between fresh and sea water is not a well-defined boundary such that on one side is found fresh water and on the other side sea water. Instead there is a zone of intermixture, commonly called the "zone of diffusion," which separates the overlying fresh water from the underlying sea water. Within the zone of diffusion
PAGE 44
34 FLORIDA GEOLOGICAL SURVEY the salinity of the water ranges from that of uncontaminated ground water to undiluted sea water. The zone of diffusion arises principally from the vacillation of the fresh water-sea water contact in response to fluctuations of the water level and the rise and fall of the tide. As indicated by Brown (1925, p. 36), European investigators found the zone of diffusion ranges in thickness from 60 to 100 feet under normal conditions. Investigations in the Miami area have shown the width of the zone of diffusion there to be 60 feet (Parker, 1945, p. 539). Salt-Water Encroachment in Pinellas County About 91 percent of the dissolved solids content of sea water consists of chloride salts. Thus, determinations of the chloride content of ground water are generally a reliable indication of the extent to which normally fresh ground water has become contaminated with sea water. More than 500 determinations of chloride content of water from wells in Pinellas County have been made. It has been found that, in general, ground water which has not been contaminated by sea water contains less than 50 ppm of chloride, whereas that which is contaminated contains up to 1,000 ppm and more. To most persons, water having a chloride content of 350 to 500 ppm has a perceptibly salty taste. The determinations of chloride content are listed in table 5. The generalized results of these determinations are shown in figure 16. As can be seen from this figure, there are four areas in the county in which a considerable number of wells yield water with a chloride content in excess of 50 ppm, and in which salt-water encroachment has likely occurred. These areas include: a small area south and east of Palm Harbor that extends from Clearwater Harbor inland for a distance of 2 to 3 miles most of the area in the vicinity of Indian Rocks, Walsingham, and Oakhurst; a narrow band about a mile wide along the southeastern coast; and a small area at the north end of Old Tampa Bay about 2 miles west of Oldsmar. Although salt water has apparently encroached into the areas described above, it can be seen from figure 16 that there are a few wells in each of the areas that yield water with a chloride content of less than 50 ppm. Conversely, there are a few wells in nearly every other part of the county that yield water with a chloride content of more than 50 ppm. These irregularities are due in part to the fact that the wells sampled varied considerably in depth, and in part to the fact that some had been pumped extensively prior
PAGE 45
REPORT OF INVESTIGATIONS No. 12 35 to sampling. As a rule the deeper wells may be expected to yield water with a higher chloride content than the shallower ones and a given well will yield water with a higher chloride content after prolonged pumping. One example of how the chloride content differs between wells of different depths may be cited. On January 28, 1947, well 458, which is 108 feet deep, had a chloride content of 25 ppm, whereas on the same day well 459, which is no more than about 0.1 mile from well 458 and is 289 feet deep, had a chloride content of 400 ppm. An example of how the chloride content increases when a well is pumped is shown in table 2, which gives the results of tests made on well 420 by V. C. Jamison of the University of Florida Citrus Experiment Station at Lake Alfred.

After it had been pumped for 15 minutes the chloride content was only 129 ppm, but after 3 hours of pumping the chloride content had risen to 2,984 ppm. The chloride content did not change significantly after the first 3 hours of pumping. Although the yield of the well is unknown, it was probably more than 100 gallons a minute. According to the Ghyben-Herzberg principle, the contact between fresh water and sea water along a section from Clearwater Harbor to Coopers Bayou would be as shown in figure 17. Several assumptions were made in drawing this section and it approximates the actual contact so far as these assumptions are correct. One as4 ,

PAGE 47
REPORT OF INVESTIGATIONS No. 12 37 sumption is that the limestone aquifer is isotropic (equally permeable in all directions) so that water may move through it vertically as well as horizontally. There appears to be no doubt that the limestone contains some layers that are less permeable than others and hence that water will move less freely vertically than horizontally. It appears likely, however, that there is enough interchange of water between the upper and lower parts of the aquifer to enable the fresh water-sea water contact to adjust, in time, to the piezometric surface. Moreover, because there are hundreds of wells in the county which have open holes through several hundred feet of limestone, there is probably a relatively free exchange of water between the different permeable zones in some parts of the county. Another assumption is that the fresh water-sea water contact is in equilibrium with the piezometric surface. The contact probably rises during times of heavy withdrawal and is depressed by fresh water entering the aquifer during the wet season. However, because the contact can rise only as the fresh water immediately above it is withdrawn from storage and replaced by sea water, a process referred to by Wentworth (1942, pp. 683-693) as "change in bottom storage," there is necessarily a lag between the time the freshwater head is lowered and. the time the contact has reached the new point of equilibrium. In fact, the recent experience of well owners in some of the coastal areas in Pinellas County, especially in the area from Clearwater to Indian Rocks, where wells have become contaminated with salt water without any detectable decline in artesian head, seems to indicate that the head declined to about its present level prior to 1947, when water-level observations were begun, and that the contact has not yet reached equilibrium with the lowered position of the piezometric surface. A study of figure 16 reveals that wells on the upland area in the vicinity of St. Petersburg (see fig. 2) yield water with a chloride content of less than 50 ppm, although numerous wells between this area and the principal recharge area near Coachman yield water with a chloride content of more than 50 ppm. Thus, it appears probable that the limestone aquifer in the vicinity of the upland area is being recharged by water percolating downward from the water-table aquifer through the confining bed. Additional evidence that local recharge is occurring in southern Pinellas County is offered by the configuration of the contour lines of the piezometric surface on figure 14.

UNDERGROUND DRAINAGE OF LAKE TARPON Lake Tarpon, formerly known as Lake Butler, in the northern part of Pinellas County, is connected by an underground channel with Spring Bayou, at Tarpon Springs (fig. 18). At irregular intervals the lake drains through this underground channel into Spring Bayou, and between drainings the salt water from Spring Bayou moves through the channel, contaminating the lake water. An explanation of how the draining occurs has been suggested by 0. E. Meinzer and V. T. Stringfield and described by H. H. Cooper, Jr. (personal communication) as follows:
PAGE 49
REPORT OF INVESTIGATIONS No. 12 39 "During the intervals between drainings the channel evidently becomes blocked in such a way as to retain the water in the lake and allow the stage to build up. Ultimately the stage builds up so high that the block is overcome, and the lake drains. The nature and mechanics of this block have been a subject of interesting speculation. "A plausible explanation of the phenomenon has been suggested by Mr. Meinzer. He points out that the underground channel, in conjunction with the vents in the lake and bayou, forms a crude U-tube, in which a column of the relatively dense sea water in Spring Bayou balances a higher column of fresh water in the lake. So long as the system is in balance, the contact between fresh water and sea water is in the lake vent at a depth which depends on the lake stage, the tide in the bayou, and the relative densities of the two waters. As the differential in head increases with a rising stage or a falling tide, this contact is depressed. When the differential in head is great enough to depress the contact to the bottom of the U, any further increase throws the system out of balance, the sea water flushes out of the channel, and the lake drains. "The lake will cease to drain when a new static balance between the two columns of water is established at a lower stage. Probably the cessation of flow occurs during a rising tide in the bayou, and subsequently, near high tide, sea water moves back through the channel into the lake vent once more to complete the cycle. "The reason that the lake stage at which flushing begins varies from one time to another is apparent when one considers that this critical stage is dependent on two variables: one is the tide level in the bayou, and the other is the density of the lake water. The density of the lake water varies with the extent to which it is mixed with sea water by the constant agitation of the tide. At times the concentration of salts in the lake water, especially in the vicinity of the sink, may be so high as to allow the lake to flush under a considerably lower head differential than if the water were altogether fresh. "The ratio of the specific gravity of sea water to that of fresh water is about 1.025 to 1.000, or 41 to 40. Thus, a column of sea water 40 feet in height will balance a column of fresh water 41 feet in height. Applied to the problem at hand, this relationship indicates that for each foot of lake stage above the bayou tide level there will be a depth of 40 feet below the bayou level to the contact between the two waters, providing the lake water is fresh. If the lowest section of the U-system were, for example, 120 feet below sea level, the highest possible head differential that could occur without flushing would be about 3.0 feet. Differentials in head of more than 3.0 feet would indicate that the lowest section of the underground channel is more than 120 feet below sea level. When additional studies have been made, it may become possible to predict with a fair degree of accuracy when flushings will occur. Investigations of the specific gravity of water at various depths in the lake sink immediately prior to the flushings are needed. Also needed are studies of the differentials in head with consideration of the time required for tidal fluctuations to be transmitted through the system." An investigation of the underground drainage of the lake was undertaken by the U. S. Geological Survey. As a part of the investigation, automatic recording gages were installed on well 13 at Tarpon Springs and on Lake Tarpon. Charts from the recorder on Lake Tarpon show, that the lake drained 27 times from July 1945 to November 1949. The stage of the lake at the start of the drainings has ranged from 2.5 to 5.5 feet above mean sea level
PAGE 50
40 FLORIDA GEOLOGICAL SURVEY and at the cessation of the drainings, from 1.2 to 3.1 feet above mean sea level. The hydrograph for well 13 (see fig. 19) shows that the water level in the area west of Lake Tarpon fluctuates in response to the changes in lake level. In fact, the fluctuations of water level in well 13 and of Lake Tarpon are almost identical. Thus, as shown in figure 19, unusual fluctuations associated with the draining of Lake Tarpon occurred in both the well and the lake in August and October of 1948 and in August, September, October, and November of 1949. The lake drains through a sinkhole having a maximum measured depth of 115 feet just off the northwest shore of the lake (fig. 18). After entering the sinkhole the water moves through an underground channel or channels and emerges through a vent in the bottom of Spring Bayou. 1947 1948 1949 J F M A M J J ASO N D J F M A M J J ASONDJ F M A M J A ASOND 4 Moon Daily Water Level -X -4_ _ _ _ _ -_ ----_ -------in Well 13 at Tarpon Springs 5 Mean Daily Stage -0 sooo , -Chlodde Content of Water ' Sin Sinkhole in Lake Tarpon 12,000 ---EXPLANATION o CNhloride at Surface 8,000 * Chloride at Bottom 2 Choride at Surface I ^and Bottom lw IW 11 20----L.Monthly Rainfall --1 5oi Tarpon Sprin F f Figure 19.-Factors relating to underground drainage of Lake Tarpon.

42 FLORIDA GEOLOGICAL SURVEY Figure 20 shows the variations in the chloride content, and thus indicates the variations in density, of the water in the lake sink during one drainage cycle. The lake stopped draining on March 30 or 31, 1949, probably during a high tide in the bayou, after which relatively salty water flushed into the lake sink, reaching almost to the surface of the lake by April 7. From April 7 to June 30, while the lake was relatively low (fig. 19), salty water remained in the lake sink, its vertical position changing, partly as a result of tides in Spring Bayou. As the lake rose, beginning in July (fig. 19), the salt water in the lake sink was depressed and diluted (fig. 20) until, sometime between August 4 and August 11, the balance between the fresh water and salt water was upset and the lake started to drain. Draining of the lake is accompanied by a partial draining of the aquifer in the area west of the lake, as indicated by the hydrograph of well 13 in figure 19. A plot of the chloride content of water at the surface and at the bottom of the sinkhole in Lake Tarpon from early 1947 to April 1948 is shown in figure 19. A comparison of this plot with the mean daily stage of the lake during 1947 shows that during the period from May to July, after the lake had drained, its level remained relatively low and salty water was present in the bottom of the sinkhole. In August, as the stage of the lake began to rise, the salty water in the sinkhole was depressed until it could no longer be reached for sampling. QUALITY OF WATER Chemical analyses of 10 samples of water from selected wells in the county, made by the Quality of Water Branch of the U. S. Geological Survey, are shown in table 3. The relative mineralization of the different samples is best observed by comparing the amount of dissolved solids. In general, such a comparison shows that mineralization increases with depth and with distance from the recharge area. Thus, the wells at Clearwater, Dunedin, Largo, and Safety Harbor, all of which are relatively near the Coachman recharge area, contained less than 300 ppm of dissolved solids, whereas the wells at Bay Pines, Oldsmar, and Pinellas Park, which are much farther from points of recharge, contained more than 900 ppm. Nitrate is derived from the decomposition of organic material, and a relatively high content of this constituent generally indicates the presence of local recharge. No analyses were made of the nitrate content of water from wells near the center of the Coachman f..
PAGE 53
REPORT OFINVESTIGATIONS No, 12 43 recharge area. However, the nitrate content of well 167 at Dunedin and well 640 at St. Petersburg was 6.0 and 6.5 ppm respectively, indicating local recharge near both these wells. As pointed out in a previous section, the possibility of local recharge at St. Petersburg is indicated also by the fact that wells in the upland part of the city yield water having a lower chloride content than wells in the area between St. Petersburg and the principal recharge area in the vicinity of Coachman. Hardness affects the suitability of water for certain uses. Among the most noticeable effects are the increased quantities of soap needed to form a lather and the scale formed in vessels when the water is heated. Most hardness is due to the presence of calcium and magnesium, although iron, aluminum, and other substances, which are generally present only in negligible quantities, contribute to it. Water having a hardness of less than 50 ppm is generally considered soft. Hardness of 50 to 150 ppm does not seriously interfere with the use of water for most purposes, although the quantity of soap required to form a lather is noticeably larger. Water having a hardness of more than 150 ppm is rated as hard and is commonly softened when used for household and other domestic uses. Each sample analyzed for this report had a hardness of more than 175 ppm. Three samples, those from Bay Pines, Oldsmar, and Pinellas Park, each had a hardness of more than 495 ppm. Studies in some areas of the United States have shown that children who drink water that contains about 1 ppm of fluoride have fewer cavities in their teeth than children who drink water that contains much less than 1 ppm (Dean, 1943, pp. 1161-1183). However, fluoride in concentrations more than 1.5 ppm tend to cause mottling of the enamel of the permanent teeth of young children who habitually use the water. In view of this, it is significant that the samples from well 167 at Dunedin and well 25 at Tarpon Springs did not contain measurable amounts of fluoride and the others contained only 0.1 to 0.6 ppm. Iron differs from most of the other chemical constituents normally found in ground water in that concentrations as low as 0.1 ppm may impart objectionable characteristics such as a ferruginous taste and the staining of plumbing fixtures. Three of the samples from Pinellas County, those from Oldsmar, Safety Harbor, and St. Petersburg, contained more than 0.1 ppm of iron. However, it appears possible that the relatively high iron contents of 0.81 ppm in well 212A at Oldsmar and 1.64 ppm in well 640 at St. Peters-

The significance of the chloride content of water is discussed in the section entitled "Salt-Water Encroachment."h a well poi USE OF WATER Nearly all water for public, industri50 feet. A few shal, agricultural, and domestic uses in Pinellas County is obtained from dug wellsd from wells. The Pinellas County Water System, which obtains part of its supply from McKay Creek, is the only public system using surfaexcept the St. Petersbur of supply at the present time, but it, also, obtains part of its supply from ground water. Wells tapping the artesian aquifer range in diameter from 3 to 12 inches and range in depth from about 50 feet to as much as 300 feet. The yield of deep wells in Hillsboroughvaries with the permeability of the limestone penetrated, the amount of open hole, and the diameter, but wells having diameters of 8 inches and more generally yield several hundred gallons a minute. Shallow wells are generally developed by driving 11/2 inch casing, equipped with a well point, to a depth of from 25 to 50 feet. A few shallow domestic suppliey a day are obtained from dug wells having diameters of 24 inches or more. The Florida State Board of Health lists 13 public water systems in Pinellas County, all of which, except the St. Petersburg system, obtain water from wells in the county. St. Petersburg obtains its water from wells in Hillsborough County. The average output of each system in 1947 (Florida State Board of Health, 1948, pp. 20-21) is given in table 4.

46 FLORIDA GEOLOGICAL SURVEY The consumption of water in Pinellas County is increasing so fast that any figures given on consumption are obsolete before publication. For example, the average daily output of the Clearwater system increased from 1.5 million gallons in 1947 to 3.2 million gallons in 1951, and that of the Pinellas County Water System increased from 0.65 to 1.5 million gallons over the same period. One of the most important items to be considered in a study of the ground-water resources of an area is the total consumption of ground water. However, because there are hundreds of domestic and irrigation wells scattered throughout Pinellas County on which no pumping records are kept, it has not been feasible to derive a consumption figure that is much more than a calculated guess. About the best estimate that can be made is that the consumption of water in Pinellas County was 13 to 14 million gallons a day in 1951. St. Petersburg Water Supply Although the investigation leading to this report was concerned primarily with the ground-water resources of Pinellas County, the report would not be complete without a discussion of the water supply of St. Petersburg, which is now obtained from 12 wells near Cosme, in northwestern Hillsborough County. The St. Petersburg supply serves approximately half the population of Pinellas County. All the wells draw water from the limestone aquifer. The water in the aquifer in the Cosme area enters the limestone formations through the recharge area in Pasco County and northern Hillsborough County. Measurements made in 1930 of the water levels in the Cosme wells indicate that the piezometric surface stood between 36 and 43 feet above sea level prior to the time the wells were put into operation (see table 5). The current average daily pumping of about 12 million gallons has doubtless created a cone of depression around the well field, but the depth and extent of the cone have not been mapped. However, a record of the water level since October 1930 in Hillsborough County well 13 (see fig. 21), about 4 miles east of the nearest supply well at Cosme, indicates that the piezometric surface has not been lowered appreciably at that distance from the well field. When it is considered that in other places in Florida, as in northeastern Florida (Cooper and Warren, 1945, pp. 263-282), the piezometric surface has been lowered substantially by heavy pumping over distances much greater than 4 miles without any serious consequences, tle record of the water level in Hills-

48 FLORIDA GEOLOGICAL SURVEY borough County well 13 appears to indicate that the ground-water resources in the Cosme area are not being unduly affected by pumping. In fact, the available information indicates that the ground water resources in the region north and east of Cosme have the capacity to yield several times the amount of water that is now being pumped, provided new wells are dispersed over an area of sufficient breadth to avoid excessive drawdowns. SUMMARY AND CONCLUSIONS The results of the investigation of ground-water resources in Pinellas County may be summarized as follows: 1. The principal source of ground water in Pinellas County is an aquifer composed of the Tampa formation and Suwannee limestone. In the northern part of the county the top of this aquifer is 10 to 50 feet beneath the surface. Toward the south its depth increases until in the vicinity of St. Petersburg it is more than 125 feet beneath the surface. In the area north of Palm Harbor and west of Lake Tarpon the water in the aquifer is under water-table conditions. In the remainder of the county the water is under artesian conditions. 2. West and south of Lake Tarpon the water in the aquifer is derived wholly from local rainfall. North of Palm Harbor the aquifer is covered only with permeable material and hence receives recharge from rainfall readily. South of Palm Harbor the aquifer is overlain by material of low permeability but nevertheless receives substantial quantities of recharge through sinkholes in the area around Coachman; the area of recharge possibly includes the vicinity of Dunedin. Recharge in this area is indicated by the fact that the piezometric surface stands high-as much as 16 feet above sea level about a mile south of Coachman. Lesser quantities of recharge doubtless enter the artesian aquifer wherever the water table stands very high above the piezometric surface, as, for example, in the upland area around St. Petersburg. 3. Salt-water encroachment is the most critical ground-water problem confronting the county. Areas already affected by encroachment include: (1) most of the area between Palm Harbor and the southwest shore of Lake Tarpon; (2) most of the area between Indian Rocks, Walsingham, and Oakhurst; (3) an area about a mile wide along the southeastern coast of the county; and
PAGE 59
REPORT OF INVESTIGATIONS NO. 12 49 (4) a small area at the north end of Old Tampa Bay about 2 miles west of Oldsmar. The chloride content of the water from wells in these areas ranges from less than 50 to as much as several thousand parts per million. The quantity of water that may be safely withdrawn from the aquifer at a given place depends on the water-transmitting capacity of the aquifer and on the height of the piezometric surface. Where the piezometric surface stands highest, more water can be withdrawn without causing salt water to move into the wells. Wherever the piezometric surface is lowered, water is removed from storage, and the water so removed is replaced in part by water from the sea. 4. In the long run, salt-water encroachment can be controlled only by limiting the total draft to a rate at which an adequate freshwater head will be maintained. Where feasible, the safe draft at a given place and from a given group of wells might be increased by artificially recharging the aquifer-that is, by injecting surplus surface water into the aquifer through wells. To be effective, however, the artificial recharge would have to be introduced in the immediate vicinity of the pumped wells. If, for example, the aquifer were artificially recharged in the vicinity of Coachman, no appreciable beneficial results would accrue to the wells in the vicinity of Walsingham, but the safe draft at Coachman might be increased. At some places, where geologic conditions are favorable, artificial recharge would be most effective if applied immediately adjacent to the coast, where it would build up a ground-water "ridge" to act as a barrier to the inland advance of sea water (Laverty and others, 1951). This approach to the problem would be effective, however, only if the aquifer were underlain by a watertight formation, for otherwise the salt water could move upward from the deeper formation, thereby bypassing the barrier. The scanty information on the geology of Pinellas County indicates that there is no watertight formation underlying the aquifer and, hence, that an attempt to halt the advance of sea water by creating a ground-water ridge along the coast probably would not be successful. Artificial recharge can put a stop to an encroachment of salt water only if the rate of recharge exceeds the rate of withdrawal. So long as the draft of ground water in Pinellas County continues to increase the problem of salt-water encroachment will grow more serious. An encroachment of salt water is especially lamentable because its effects are long lasting. Having once established inroads
PAGE 60
50 FLORIDA GEOLOGICAL SURVEY into the aquifer, the salty water will rinse out only very slowly, leaving traces for many years and perhaps for generations after remedial measures are undertaken. The investigation leading to this report was restricted largely to a study of the existing wells in the county, because funds for drilling test wells and observation wells were not available. As most of the wells are finished with open holes that extend through more than 100 feet of limestone and thus draw from more than one water-bearing zone, several aspects of the problem of salt-water encroachment could not be investigated. Among these are (1) the relation between the height of the piezometric surface and the depth below sea level of the fresh water-sea water contact, (2) the rate of advance of the contact in the areas already affected by salt-water encroachment, and (3) the possibility of differences in pressure heads between various water-bearing zones. The relation between the height of the piezometric surface and the depth to the salt-water contact must be studied before the problem of salt-water encroachment can be adequately understood. Figure 17 was drawn on the basis of the Ghyben-Herzberg principle, described in the section titled "Salt-Water Encroachment," to show where the contact would be if it were in hydrostatic equilibrium with the piezometric surface. The position of the contact as shown in figure 17 may differ from the true position because the permeability of the aquifer in a vertical direction is doubtless much less than the permeability in a horizontal direction, and because vertical movements of the contact that accompany changes in the height of the piezometric surface are delayed by changes in "bottom storage." On the other hand, if the Ghyben-Herzberg principle is found to apply approximately, the effects of pumping at a given place can be predicted fairly well. Studies are needed also to determine the rate at which saltwater encroachment is occurring. Water samples for chloride analyses have been collected from selected wells several times since 1948 in an effort to determine the rate of encroachment. However, the results of these analyses have not been consistent, because each well draws from several water-bearing zones so that the samples are mixtures of water from several depths, and possibly because intermittent pumping of the wells by the owners causes the chloride content to vary inconsistently from one sampling to another. Where the rate of encroachment can be determined it may be possible to predict when the wells will become contaminated.
PAGE 61
REPORT OF INVESTIGATIONS No. 12 51 A program designed to determine how closely the GhybenHerzberg principle applies and to observe the advance of the saltwater contact would consist of establishing a series of observation stations approximately 1 mile apart across the county from Clearwater to Tampa Bay. Each station should consist of three or four small-diameter wells drilled and cased to different depths in the aquifer. The deepest of the wells would end in the zone of diffusion between fresh water and salt water, the shallowest would end near the top of the aquifer, and the other one or two would end at intervening depths. Such a system of wells would provide a means of extracting water samples and measuring pressure heads at isolated depths in the aquifer, an operation that is not possible with the existing, open-hole wells. Tests of chloride content of water from the wells of each station would indicate how the salt-water contact advances and retreats, and measurements of the water levels would provide a record of the changes in pressure head that cause the contact to advance and retreat. Similar stations could well be established in each of the areas affected by salt-water encroachment to provide accurate information on how the extent of the encroachment may increase or decrease. Further analyses of the chloride content of water from many wells throughout the county, at least once a year, would provide much needed additional information on the extent of salt-water encroachment. As of February 1, 1953, five recorders were in operation (on wells 13, 77, 166, 246, and 561), three having been discontinued because the owners of the wells rightfully elected to restore the wells to their own service. As the height of the piezometric surface controls the extent to which salt water will encroach, it is especially desirable that records of water levels such as are obtained through the use of automatic recording gages be continued indefinitely on at least five or six wells strategically located over the county.
