WATER LEVELS IN -ARTESIAN AND NONARTESIAN
AQUIFERS OF FLORIDA, 1963-64

By
Henry G. Healy

INTRODUCTION

This report summarizes the trends and fluctuations of groundwater levels in the principal aquifers in Florida during 1963-64 and includes the following: (1) hydrographs of ground-water levels in the several aquifers; (2) maps showing changes in ground-water levels during specific periods; and, (3) a table summarizing the principal data on selected observation wells. Observation wells for which records are available are listed in the "Index to Water Resources Data-Collection Stations in Florida, 1961", Florida Geological Survey Special Publication No. 11, which includes the location, aquifer, and type and period of records available for about 3,600 observation wells.
Since World War II, and particularly during the last decade, the demand for fresh water for industrial, municipal, and agricultural use in Florida has increased yearly. Although ground-water supplies have been adequate for the increased demand in most areas in Florida, water levels have declined appreciably in some areas. Because demand for ground water continues to increase, shortages will occur and may become critical in some areas. In coastal areas, declining water levels may allow salt water to encroach and shortages could result from deterioration in quality as well as from the reduction of quantity of water available. In order to prevent future shortages, the supplies of ground water must be properly appraised before they can be effectively utilized. Records of trends and fluctuations of ground-water levels have long formed a basis for such an appraisal.
The principal objective of the Water Resources Division of the U.S. Geological Survey is to appraise and to evaluate the Nation's water resources. Although many types of ground-water investigations are conducted throughout the Nation, the collection and compilation of basic hydrologic data constitute an important part of the water-resources studies.
Objectives of the hydrologic data program include: the evaluation of available ground-water supplies; the prediction of trends





DIVISION OF GEOLOGY


of water levels; and the delineation of present or potential areas of detrimentally high or low ground-water levels. Water levels are also used to predict the base flow of streams, to portray the effects of natural and man-induced forces that act on a water-bearing formation, and to furnish information for use in research. The hydrologic data program is an important adjunct of the several types of geologic and hydrologic methods of study used in waterresources investigations.
The hydrologic data-collection program of the U. S.. Geological Survey is part of the cooperative investigations of the ground-water resources of Florida, in Cooperation with the Division of Geology, Florida Board of Conservation, and other state and local agencies and municipalities. The observation-well network in 1964 included about 1,000 observation wells in the 67 counties of the State. Figure 1 shows the locations of these observation wells and Table 1 lists data for 329 observation wells selected from the statewide network.
The hydrologic-data program consists of the collection, tabulation, interpretation, evaluation, and publication of water-level and related data. Water levels for selected wells are published, at present, once every 5 years in the U. S. Geological Survey Water-Supply Papers.
Information pertinent to ground water is also published in interpretative reports of investigations published by the Florida Geological Survey and the U. S. Geological Survey. Data collected during an investigation and subsequent to publication are available from the District Chief; U. S. Geological Survey, P. 0. Box 2315, Tallahassee, Florida 32304.
The water-level data used in this report represent measurements taken from automatic water-stage recorder charts, pressure gages, and made by wet tape. In general, water-level measurements made by tape and stage recorder are shown to the nearest hundredth of a foot, and those made with a pressure gage are shown to the nearest tenth of a foot.
Table 1 summarizes well-data and water-level information for the several aquifers. Well data include the aquifer, depth of well, and depth of casing. The items: "Year record began" and "Frequency of measurements" are included as part of the well data. In the water-level portion of the table, levels for May or June are used because records are available for these months for a large percentage of the wells. Also, ground-water levels generally are lowest during May or June in many areas and records during that

Table l.--Summary of well data and water levels in selected-observation veils.

Well number: Well numbers are based on county numbering system e.g. Bay County well Bay 20, or on the latitudinal and longitudinal system e.g. well 008-537-2. Both numbers 20 and 008-537-2 are given where this well has been reported previously in a publication under the county number. Letters prefixed to well, numbers in Broward and Dade Counties; G, Geological Survey wells,; S, supply wells.; F, fire wells; and
NP. National Park Service wells. Letter suffix A, shallow well adjacent to deep well.
Aquifer: B. Biscayne; F. Floridan; G, sand-and-gravel; H, Havthorn; HA, nonartesian; S, shallow sand. Depth of well: Measured unless otherwise noted. R, reported depth. Prequency of measurement: Refers to current biennium. B, bimonthly; C. continuous; M, monthly; S, semianually; W. weekly.
Prior to 1963: When only one measurement is available prior to current biennium, measurement is arbitrarily
listed as a low level.
Water level: To hundredth of a foot if measured by vet-tape method or taken from recorder chart; to nearest
tenth of a foot if measured by pressure gage or airline.
Annual range: Based on measurements available during year. For wells equipped with recorder, range is
based on every 5th day measurements.
Remarks: B, water level below measuring point; D, measurements discontinued on date shown in Remarks;
L. lowest water level; M, water level with reference to mean sea level; P, water level affected by
pumping of nearby vells; R, recorder installed on date shown in Remarks; S, water level affected by
seasonal or regional pumping; T, water levels affected by ocean tides.

WELL-NUMBERING SYSTEM

Two well-numbering systems are used in this report. 'Observation wells in Florida are numbered serially by counties and/or by a grid-coordinate system on latitude and longitude of the well location. Frequently, both numbers are assigned to a well e.g. a well number may be shown as 20(008-537-2). This affords a tie-in with water-level data published previously under well number 20 in Bay County with data that may be published for the same well under number 008-537-2.
Some wells used in table 1 have numbers with a letter prefix or suffix. In Broward and Dade counties, the letter prefixes G, S, F, and NP denote Geological Survey wells, supply wells, fire wells, and National Park Service wells, respectively. In Dade, Escambia, Highlands, Holmes, and Leon counties, the letter suffix A denotes a shallow well near a deeper well having the corresponding number without the letter suffix. In Orange County, the letter suffixes B and C denote shallow wells drilled in the vicinity of well 47.
The grid-coordinate well-numbering system in Florida is derived from latitude and longitude coordinates. The latitude and longitude prefix north and west and the first digit of the degree number are not included in the well number.
The well number is a composite of three numbers separated by hyphens: the first number is composed of the last digit of the degree and the two digits of the minute that define the latitude on the south side of the 1-minute quadrangle; the second number is composed of the last digit of the degree and two digits of the minutes that define the longitude on the east side of a 1-minute quadrangle; and, the third number gives the- numerical order in which the well was inventoried in the 1-minute quadrangle. For example, well number 835-105-1 is the first well inventoried in the 1-minute quadrangle north of the 28035' parallel of latitude and west -of the 81005' meridian of longitude. The location of well 835-105-1 is shown diagrammatically in figure 2.

PRINCIPAL AQUIFERS

Ground-water supplies for industrial, agricultural, and municipal use in Florida are available from three principal aquifers: the Floridan aquifer in central and northern Florida; the Biscayne aquifer in southeastern Florida; and, the sand-and-gravel aquifer in the extreme northwestern part of Florida. The generalized areal extent of the aquifers supplying most of the ground water is shown in figure 1.
The Floridan aquifer, which underlies all of the State, is the principal source of water in central, northern, and most of northwestern Florida, as shown on figure 3. Highly mineralized

INFORMATION CIRCULAR NO. 52


water precludes the usefulness of the Floridan aquifer as a source of potable water in some coastal areas and in most of southern Florida. In those areas, shallow artesian and nonartesian aquifers are the source of supply.
The Biscayne aquifer in southeastern Florida is the chief source of water supply for industries, municipalities, and irrigation. This aquifer, one of the most highly productive aquifers in the world, underlies about 3,500 square miles of Broward, Dade, and Palm Beach counties. The usefulness of the Biscayne aquifer is sharply restricted in areas adjacent to the coast because of the presence of saline waters.
The sand-and-gravel aquifer in extreme northwestern Florida is the principal source of water supply, yielding large quantities of water for industries and municipalities. The aquifer underlies all of Escambia and Santa Rosa counties and part of western Okaloosa County.
This report of ground-water conditions has been divided into four geographical areas as follows: (1) northwestern Florida,
(2) northern, northeastern, and north-central Florida; (3) central Florida; and, (4) southern and southeastern coastal Florida.


NORTHWESTERN FLORIDA

Northwestern Florida as used here includes the Panhandle region extending from the Apalachicola River westward to the Florida-Alabama line, figure 4.
The principal sources of ground-water supply in the region are the sand-and-gravel aquifer in Escambia and Santa Rosa counties and the Floridan aquifer in the rest of the region. Minor supplies of ground water are obtained from shallow nonartesian aquifers.
The Florida Panhandle includes three rapidly growing areas of industry and population: the Pensacola area, the Ft. Walton Beach area, the Panama City area.

PENSACOLA AREA

The Pensacola area includes Escambia and Santa Rosa counties. This area, like many others in the State, is undergoing rapid economic development. Industrial and municipal water uses are increasing. Pumpage in the Pensacola area in 1964 was about five times that in 1940. Figure 5 shows pumpage for the City of Pensacola, 1933-64.

Figure 5. Graph of total yearly pumpage, City of Pensacola.

The observation-well program in the Pensacola area began in 1939 as part of the investigation to determine the adequacy and permanency of ground-water supply in Escambia County. Figure 4 shows locations of the observation wells selected from the hydrologic-data network for which hydrographs are given in this report, and table 1 presents data on 13 wells in Escambia County and 5 wells in Santa Rosa County. Figure 6 shows fluctuations and long-term trends of artesian water levels in the sand-and-gravel aquifer in the Pensacola area from 1940 through 1964.
Comparison of the hydrographs for the period of record reveals that while water levels at the end of 1964 declined in central Escambia County, water levels in the southern part of the county near the coast were above 1940 levels. Declines of artesian water levels in the sand-and-gravel aquifer ranged from a maximum of nearly 35 feet in well Escambia 45 at Cantonment to a minimum of less than 2 feet in well Escambia 46 near Ensley during 194164.
In the coastal area, at Pensacola, the artesian water level in well Escambia 62, at the end of 1964, was about 2 feet above the 1942 level. The trends and fluctuations of artesian groundwater levels in well Escambia 62 and departures from monthly average rainfall at Pensacola, 1960-64 are shown in figure 7.

FT. WALTON AREA

The Ft. Walton area includes the Ft. Walton Beach area and Eglin Air Force Base at Niceville. The rate of growth of industry and population is accelerating. Pumpage from the Floridan aquifer for all uses is about 10.0 mgd (million gallons per day). As a result of continuing heavy pumping, water levels have declined in about a 640 square-mile area.
The hydrograph of well Okaloosa 3 at Ft. Walton Beach, figure 8, shows a maximum decline of 98.3 feet from 18.5 feet above land surface in 1947 to 79.8 feet below land surface in 1964. In August 1936, the artesian water level was 46 feet above land-surface datum. During the period from August 1936 to July

1964, the water level in well Okaloosa 3 declined 125 feet, from 46 feet above land surface to 79 feet below land surface. The areal extent of the decline in artesian levels in the vicinity of Ft. Walton Beach is shown by the net change of water levels map, figures 9 and 10. Water-level changes during 1951-62 are shown by figure 9. Changes of groundwater levels for the current period May 1962-64 are shown by figure 10.

PANAMA CITY AREA

The Panama City area includes 250 square miles in Bay County, including Tyndall Air Force Base.
The Floridan aquifer supplies most of the water for municipal, industrial, and military needs in the area. Figure 11 shows total pumpage from the Panama City well fields at St. Andrews and Millville for the period 1944-64. Pumpage of ground water for municipal use declined from an average of 1,200 mgy (million gallons per year) in 1961-62 to an average of 860 mgy in 1963-64. To some extent, reduced pumpage by Panama City and a change in locale of source of water by the pulp industry allowed water levels to rise sharply during 1963-64. Instead of the usual fall and winter rise of 2 to 7 feet, water levels rose 24 feet from 78 feet to 54 feet below land surface from June 1963 through December 1964. The alteration of the pattern of fluctuations of water levels was probably also the result of above average annual rainfall in the area during 1964.
The long-term trends and fluctuations of ground-water levels at Panama City are shown by the hydrograph of well Bay 7, figure 12. The decline of water level in well Bay 7 represents the maximum known decline in the area and is caused by pumping in nearby wells. In August 1936, the water level in well Bay 7 was about 36 feet below land surface, while in June 1963, it was about 78 feet below land surface, a maximum decline of 42 feet.

NORTHERN AND NORTH-CENTRAL FLORIDA

central and eastern St. Johns, Flagler, and Volusia counties. Another source of water in these areas is a shallow, nonartesian, sand-and-shell aquifer.

TALLAHASSEE AREA

The Tallahassee area includes central Leon County and the City of Tallahassee. The area is primarily residential and only sparse light industry is located in this area.
The principal water user, the City of Tallahassee, supplies water for municipal use to the most rapidly growing residential and educational complex in the Big Bend. Since 1945, annual municipal pumpage at Tallahassee has increased 365 percent from about S50 mgy to 3,100 mgy. Figure 14 shows pumpage during 1933-64 for the City of Tallahassee.
Fluctuations of water levels in the Floridan aquifer at Talla hassee are shown by the hydrograph, figure 15, of well Leon 7, which shows a downward trend during 1960-63 and an upward trend in response to above average rainfall during 1964. The graph shows characteristic seasonal trends with high levels in the spring and low levels in the fall. Figure 16 shows water levels in well Leon T for the period 1945-64.

FERNANDINA-JACKSONVILLE AREA

The Fernandina-Jacksonville area is one of the largest industrialized areas in the State, with water use increasing as a result of the rapid economic expansion. Figure 17 shows total yearly municipal pumpage for Jacksonville from 1921-64.
Ground-water levels in the Fernandina-Jacksonville area have been declining for a considerable period of time. Trends and seasonal fluctuations of the. water levels in the Floridan aquifer at Jacksonville are shown for well Duval 122 and for well Duval 164 near Mayport. Hydrographs of wells'in the Floridan aquifer in Nassau and Duval counties are shown in figures 16 and 18.
Water levels declined to near record low levels in many wells in the area during 1963. Maximum decline of water levels occurred in well Nassau 12 in the Fernandina area. Levels, in this well, declined 47 feet from 29 feet above to 18 feet below land surface during 1946-63. The maximum decline was 59 feet for the period of record 1939-63. In contrast, water levels in well Nassau 51, approximately 20 miles inland, declined only .about 13 feet during 1945-46. Water levels in well Duval 122 at Jacksonville declined nearly 22 feet from 1930 to 1964, while along the coastal area in Duval County water levels generally declined about 18 feet in well Duval 164. These declines are part of the broad regional

The principal source of ground-water supply in western coastal and central peninsular Florida is the Floridan aquifer. In the eastern coastal area, the nonartesian shallow-sand aquifer is the chief source.
Central Florida includes four rapidly growing centers of population and industry: the Tampa-St. Petersburg area, the Lakeland area, the Orlando-Cape Kennedy area, the Sarasota-Bradenton area.

TAMPA-ST. PETERSBURG AREA

This area, particularly in the vicinity of Tampa and St. Petersburg, is undergoing a rapid expansion in both industry and population.The long-term trends and fluctuations of ground-water levels in the Floridan aquifer in the Tampa-St. Petersburg area are shown in figure 21. The hydrographs show a similarity of waterlevel fluctuations in well Pasco 13 near Ehren and well Hillsborough 13 near Citrus Park, during the period 1945 through 1962. Drought conditions and increased pumping during 196 1-64 caused water levels in Hillsborough 13 to decline to the lowest levels of record in 1964.

This decline is part of an extensive regional lowering of water levels which extends from southern Hillsborough County into Sarasota County. (See figure on page 54)..
Water levels in two Pinellas County wells, Pinellas 13 and 246, are shown in figure 23. No apparent trend is noted for Pinellas 13. However, a slight downward trend from 1946 through 1956 can be noted for Pinellas 246. This downward trend .was reversed during the latter part of 1956 and levels continued to rise through 1959 and were about ayerage for the period of record 1963-64.
The changes in chloride content of water from two wells in the Floridan aquifer. in Pinellas County are shown in figure 24.

The chloride content of well Pinellas 166 at Dunedin ranged frQm about 20 ppm to 1,000 ppm during the same period. The chloride content in both wells decreased during 1957-61. During 1963-64 the chloride content in well 592 increased nearly to the 1959 concentration. In contrast, the chloride content in well 166 remained low during 1963-64 and at the end of the year was well below the 1959 concentration.

Precipitation recorded at Lakeland shows deficient rainfall in the Lakeland area during the years 1961 through 1964.
In many areas in northern Polk County, water levels after declining to new record low levels during 1960-62 rose sharply in 1963 and declined slightly in 1964. From record low water levels of May 1962, levels in the Floridan aquifer recovered nearly 12 feet in well Polk 45 in the heavily pumped area south of Lakeland and nearly 3 feet in well Polk 44 near Davenport in northeastern Polk County. Levels in the nonartesian aquifer in well Polk 47 near Davenport rose about 2 feet in 1963. Although water levels rose during 1963, downward trends of levels in artesian and nornartesian aquifers continued. During 1964 water levels ranged from

Water levels in the artesian aquifer, in southern Polk County, and in the shallow-sand aquifer, in southeastern Polk County and in central Highlands County, are shown in figure 28.
The most prominent .features illustrated by the hydrographs in figure 28 are the fluctuation of water levels in the artesian aquifer and in the shallow-sand aquifer caused by the droughts of 1955-56 and 1961-62 and subsequent recovery of levels during post-drought periods.
In southern Polk County at Frostproof, water levels declined about 11 feet in the artesian aquifer in well Polk 51 from January 1960 to May 1962. In central Highlands County near Sebring, levels declined nearly 6 feet in the nonartesian aquifer in well Highlands 10 during the same period. During 1962 ground-water levels rose sharply. However, in most wells, the recovery of levels in 1963-64 did not exceed those of 1960. Water levels during 1964 ranged from 1.5 feet below 1960 highest levels in the artesian aquifer at Frostproof to 5.1 feet lower than 1960 levels in the nonartesian aquifer in central Highlands County. In southern Osceola and southeastern Highlands counties, 1963-64 water levels in the nonartesian aquifer ranged from 1 foot lower in wells Osceola 183 and Okeechobee 3 to 2.4 feet lower than 1960 levels in well Highlands 13.

Comparison of the hydrograph of well Manatee 92 to that of well Sarasota 9 shows that the decline is accelerating in Manatee County. The regional extent of the decline is shown by hydrographs of well Hillsborough 30 (fig. 23) and wells Manatee 92 and Sarasota 9 (fig. 33). The decline includes .an area of about at least 600 square miles extending from southern Hillsborough County to northern Sarasota County.

SOUTHERN FLORIDA

The southern Florida region includes all counties south of a line through Desoto County and covers an area of about 17,500 square miles. The region and the locations of selected observation wells for which hydrographs are presented are shown on figure 34.
In southern Florida, nonartesian aquifers are the principal source of water supply. In the coastal areas of Martin and Palm Beach counties, a nonartesian shallow-sand aquifer is the chief source of supply; in Broward and Dade counties, the Biscayne aquifer is the principal source; and in southwestern coastal Florida and inland areas, nonartesian shallow-sand and shell aquifers are the main sources.

FT. MYERS AREA

The Ft. Myers area includes Lee and Charlotte counties, and like the Bradenton-Sarasota area to the north is developing rapidly as a winter tourist and retirement center.
The principal source of ground water in the Ft. Myers area is the nonartesian aquifers. Figure 35 shows the seasonal fluctuations of ground-water levels in well Lee 246 and rainfall at Ft. Myers for the period 1960-64. Generally, seasonal fluctuations of water levels in nonartesian aquifers closely correspond to seasonal fluctuations in the amounts of rainfall. Figure 36 shows the trends and fluctuations of water levels in nonartesian aquifers for selected wells in southern Florida.

STUART-WEST PALM BEACH AREA

This area includes coastal parts of Martin and Palm Beach counties and is a segment of the rapidly growing, populous, coastal complex extending from Jacksonville southward through the Keys Average yearly municipal pumpage at- Stuart increased nearly 450 percent between 1941-45 and 1961-64 as shown in figure 37.
The principal source of water 'supply in the Stuart area is the

nonartesian shallow-sand aquifer. Trends of water levels in the nonartesian aquifer at Stuart are shown in figure 36. The hydrograph of well Martin 147 shows a downward trend of nonartesian levels. Levels declined to a record-low level of about 2 feet above mean sea level in the spring of 1962 and 1963. The declines during 1961-63 were caused, in part, by increased pumping in the Stuart well field. Although pumpage increased during 1964, water levels rose in response to above average rainfall. Figure 38 shows trends of water levels and rainfall recorded at Stuart, 1960-64.

Lauderdale Dixie well field and in wells Dade F296 and F64 in North Miami Beach and Miami. The chloride content in well Broward S830 declined from about 3700 ppm in 1947 to the lowest chloride content of record in 1958. The chloride content increased from the low of 1958 to nearly 2000 ppm in 1963.





DIVISION OF GEOLOGY


MIAMI AREA

The Miami area includes Broward and Dade counties and is
the most populous area in the State. The principal source of water
supply is the Biscayne aquifer, the extent of which is shown on
figure 1.
The locations of selected observation wells in the Miami
area for which hydrographs are given, are shown by figure 34.
Water-level observations were made as early as -1933 near
Homestead in well Dade S196A. Long-term record of water-level
fluctuations at Homestead are shown in figure 41. Figure 43 shows
trends of water levels and rainfall recorded at Homestead Experi-
mental Station 1960-64.
Except for the relatively narrow coastal strip, most of the
Miami area is occupied by the Everglades. Fluctuations of ground-
water levels in the Everglades are shown by hydrographs of wells
Dade G72, G596, G618, and G620, figures 44 and 45.
Fluctuations of ground-water levels in the Biscayne aquifer
in the vicinity of Miami are illustrated by hydrographs of wells
Dade G10 about 5 miles west of Miami, Dade S19 at Miami Springs
(fig. 44), and well Dade F179 at Miami (fig. 41). The water level
in well Dade S19 is affected by pumping in the municipal well
field of the City of Miami.
In the Miami area, as in other coastal areas, the presence of
salty water in an aquifer is signalled by high chloride content of
the ground water. The seaward reaches of the Biscayne Aquifer
contain sea water and some encroachment of sea water into the
aquifer has occurred through the years. Water control measures
have checked the encroachment and as a result a freshening of
the ground water has occurred in some areas.
Generally, chloride content of ground water decreased in the
Miami area and in southern coastal Dade County during 1963-64.
Figure 42 shows fluctuations of chloride content of ground water
in the Biscayne aquifer in the Miami area. Chloride content of
ground water in well Dade F64 in Miami decreased to the lowest of
record since 1947. During 1963-64, chlorides ranged from 250 to
550 ppm in this well. Chloride content of ground water in the
Biscayne aquifer ranged from 400 to 700 ppm in well F296 on the
coast north of Miami. Chloride content was generally lower during
1963-64 than during 1962. Near the eastern edge of the Miami well
field area in Miami Springs, chloride content decreased from 900

ppm in 1946 to 100 ppm in 1962 in well Dade G354. During 1963-64, chloride content decreased to the lowest of record in this well.
In southern coastal Dade County, chloride content of ground water in the Biscayne aquifer generally decreased or remained at low concentrations in several areas during 1963-64. Chloride content decreased to less than 500 ppm in well Dade S529 on the coast and that of well Dade G212 southeast of Homestead remained at less than 200 ppm during 1963-64. In sharp contrast, the chloride content in well Dade G469 near the coast south of Miami increased from about 20 ppm in 1961 to about 8600 ppm in 1964 as a result of new canal construction in that area.
In the Miami area, as in other coastal areas, the contamination of the Biscayne aquifer by the encroachment of salty water is 'an ever-present problem. Through intensive practice of water control the problem of prevention of salt-water contamination has been solved. In many areas where contamination existed the situation

Healy INTRODUCTION This report summarizes the trends and fluctuations of groundwater levels in the principal aquifers in Florida during 1963-64 and includes the following: (1) hydrographs of ground-water levels in the several aquifers; (2) maps showing changes in ground-water levels during specific periods; and, (3) a table summarizing the principal data on selected observation wells. Observation wells for which records are available are listed in the "Index to Water Resources Data-Collection Stations in Florida, 1961", Florida Geological Survey Special Publication No. 11, which includes the location, aquifer, and type and period of records available for about 3,600 observation wells. Since World War II, and particularly during the last decade, the demand for fresh water for industrial, municipal, and agricultural use in Florida has increased yearly. Although ground-water supplies have been adequate for the increased demand in most areas in Florida, water levels have declined appreciably in some areas. Because demand for ground water continues to increase, shortages will occur and may become critical in some areas. In coastal areas, declining water levels may allow salt water to encroach and shortages could result from deterioration in quality as well as from the reduction of quantity of water available. In order to prevent future shortages, the supplies of ground water must be properly appraised before they can be effectively utilized. Records of trends and fluctuations of ground-water levels have long formed a basis for such an appraisal. The principal objective of the Water Resources Division of the U.S. Geological Survey is to appraise and to evaluate the Nation's water resources. Although many types of ground-water investigations are conducted throughout the Nation, the collection and compilation of basic hydrologic data constitute an important part of the water-resources studies. Objectives of the hydrologic data program include: the evaluation of available ground-water supplies; the prediction of trends 1

Water levels are also used to predict the base flow of streams, to portray the effects of natural and man-induced forces that act on a water-bearing formation, and to furnish information for use in research. The hydrologic data program is an important adjunct of the several types of geologic and hydrologic methods of study used in waterresources investigations. The hydrologic data-collection program of the U. S.. Geological Survey is part of the cooperative investigations of the ground-water resources of Florida, in cooperation with the Division of Geology, Florida Board of Conservation, and other state and local agencies and municipalities. The observation-well network in 1964 included about 1,000 observation wells in the 67 counties of the State. Figure 1 shows the locations of these observation wells and Table 1 lists data for 329 observation wells selected from the statewide network. The hydrologic-data program consists of the collection, tabulation, interpretation, evaluation, and publication of water-level and related data. Water levels for selected wells are published, at present, once every 5 years in the U. S. Geological Survey Water-Supply Papers. Information pertinent to ground water is also published in interpretative reports of investigations published by the Florida Geological Survey and the U. S. Geological Survey. Data collected during an investigation and subsequent to publication are available from the District Chief, U. S. Geological Survey, P. O. Box 2315, Tallahassee, Florida 32304. The water-level data used in this report represent measurements taken from automatic water-stage recorder charts, pressure gages, and made by wet tape. In general, water-level measurements made by tape and stage recorder are shown to the nearest hundredth of a foot, and those made with a pressure gage are shown to the nearest tenth of a foot. Table 1 summarizes well-data and water-level information for the several aquifers. Well data include the aquifer, depth of well, and depth of casing. The items: "Year record began" and "Frequency of measurements" are included as part of the well data. In the water-level portion of the table, levels for May or June are used because records are available for these months for a large percentage of the wells. Also, ground-water levels generally are lowest during May or June in many areas and records during that

4 DIVISION OF GEOLOGY Table l.--Summary of well data and water levels in selected-observation wells. Well number: Well numbers are based on county numbering system e.g. Bay County well Bay 20, or on the latitudinal and longitudinal system e.g. well 008-537-2. Both numbers 20 and 008-537-2 are given where this well has been reported previously in a publication under the county number. Letters prefixed to well, numbers in Broward and Dade Counties; G, Geological Survey wells,; S, supply wells; F, fire wells; and NP, National Park Service wells. Letter suffix A, shallow well adjacent to deep well. Aquifer: B, Biscayna; F, Floridan; G, sand-and-gravel; H, Hawthorn; NA, nonartesian; S, shallow sand. Depth of well: Measured unless otherwise noted. R, reported depth. Prequency of measurement: Refers to current biennium. B, bimonthly; C, continuous; M, monthly; S, semiannually; W. weekly. Prior to 1963: When only one measurement is available prior to current biennium, measurement is arbitrarily Listed as a low level. Water level: To hundredth of a foot if measured by vet-tape method or taken from recorder chart; to nearest tenth of a foot if measured by pressure gage or airline. Annual range: Based on measurements available during year. For wells equipped with recorder, range is based on every 5th day measurements. Remarks: B, water level below measuring point; D, measurements discontinued on date shown in Remarks; L. lowest water level; ,M water level with reference to mean sea level; P, water level affected by pumping of nearby wells; R, recorder installed on date shown in Remarks; S, water level affected by seasonal or regional pumping; T, water levels affected by ocean tides.

20 DIVISION OF GEOLOGY period constitute a base for comparison from year to year. Highest and lowest water levels of record for May or June prior to 1963 are given in the table. Generally, highest and lowest levels are highest daily levels if taken from recorder charts. The range of fluctuations for 1963 and 1964 are shown under "Annual range" WELL-NUMBERING SYSTEM Two well-numbering systems are used in this report. 'Observation wells in Florida are numbered serially by counties and/or by a grid-coordinate system on latitude and longitude of the well location. Frequently, both numbers are assigned to a well e.g. a well number may be shown as 20(008-537-2). This affords a tie-in with water-level data published previously under well number 20 in Bay County with data that may be published for the same well under number 008-537-2. Some wells used in table 1 have numbers with a letter prefix or suffix. In Broward and Dade counties, the letter prefixes G, S, F, and NP denote Geological Survey wells, supply wells, fire wells, and National Park Service wells, respectively. In Dade, Escambia, Highlands, Holmes, and Leon counties, the letter suffix A denotes a shallow well near a deeper well having the corresponding number without the letter suffix. In Orange County, the letter suffixes B and C denote shallow wells drilled in the vicinity of well 47. The grid-coordinate well-numbering system in Florida is derived from latitude and longitude coordinates. The latitude and longitude prefix north and west and the first digit of the degree number are not included in the well number. The well number is a composite of three numbers separated by hyphens: the first number is composed of the last digit of the degree and the two digits of the minute that define the latitude on the south side of the 1-minute quadrangle; the second number is composed of the last digit of the degree and two digits of the minutes that define the longitude on the east side of a 1-minute quadrangle; and, the third number gives the numerical order in which the well was inventoried in the 1-minute quadrangle. For example, well number 835-105-1 is the first well inventoried in the 1-minute quadrangle north of the 28035' parallel of latitude and west of the 81005' meridian of longitude. The location of well 835-105-1 is shown diagrammatically in figure 2.

22 DIVISION OF GEOLOGY PRINCIPAL AQUIFERS Ground-water supplies for industrial, agricultural, and municipal use in Florida are available from three principal aquifers: the Floridan aquifer in central and northern Florida; the Biscayne aquifer in southeastern Florida; and, the sand-and-gravel aquifer in the extreme northwestern part of Florida. The generalized areal extent of the aquifers supplying most of the ground water is shown in figure 1. The Floridan ,aquifer, which underlies all of the State, is the principal source of water in central, northern, and most of northwestern Florida, as shown on figure 3.

INFORMATION CIRCULAR NO. 52 23 water precludes the usefulness of the Floridan aquifer as a source of potable water in some coastal areas and in most of southern Florida. In those areas, shallow artesian and nonartesian aquifers are the source of supply. The Biscayne aquifer in southeastern Florida is the chief source of water supply for industries, municipalities, and irrigation. This aquifer, one of the most highly productive aquifers in the world, underlies about 3,500 square miles of Broward, Dade, and Palm Beach counties. The usefulness of the Biscayne aquifer is sharply restricted in areas adjacent to the coast because of the presence of saline waters. The sand-and-gravel aquifer in extreme northwestern Florida is the principal source of water supply, yielding large quantities of water for industries and municipalities. The aquifer underlies all of Escambia and Santa Rosa counties and part of western Okaloosa County. This report of ground-water conditions has been divided into four geographical areas as follows: (1) northwestern Florida, (2) northern, northeastern, and north-central Florida; (3) central Florida; and, (4) southern and southeastern coastal Florida. NORTHWESTERN FLORIDA Northwestern Florida as used here includes the Panhandle region extending from the Apalachicola River westward to the Florida-Alabama line, figure 4. The principal sources of ground-water supply in the region are the sand-and-gravel aquifer in Escambia and Santa Rosa counties and the Floridan aquifer in the rest of the region. Minor supplies of ground water are obtained from shallow nonartesian aquifers. The Florida Panhandle includes three rapidly growing areas of industry and population: the Pensacola area, the Ft. Walton Beach area, the Panama City area. PENSACOLA AREA The Pensacola area includes Escambia and Santa Rosa counties. This area, like many others in the State, is undergoing rapid economic development. Industrial and municipal water uses are increasing. Pumpage in the Pensacola area in 1964 was about five times that in 1940. Figure 5 shows pumpage for the City of Pensacola, 1933-64.

The observation-well program in the Pensacola area began in 1939 as part of the investigation to determine the adequacy and permanency of ground-water supply in Escambia County. Figure 4 shows locations of the observation wells selected from the hydrologic-data network for which hydrographs are given in this report, and table 1 presents data on 13 wells in Escambia County and 5 wells in Santa Rosa County. Figure 6 shows fluctuations and long-term trends of artesian water levels in the sand-and-gravel aquifer in the Pensacola area from 1940 through 1964. Comparison of the hydrographs for the period of record reveals that while water levels at the end of 1964 declined in central Escambia County, water levels in the southern part of the county near the coast were above 1940 levels. Declines of artesian water levels in the sand-and-gravel aquifer ranged from a maximum of nearly 35 feet in well Escambia 45 at Cantonment to a minimum of less than 2 feet in well Escambia 46 near Ensley during 194164. In the coastal area, at Pensacola, the artesian water level in well Escambia 62, at the end of 1964, was about 2 feet above the 1942 level. The trends and fluctuations of artesian groundwater levels in well Escambia 62 and departures from monthly average rainfall at Pensacola, 1960-64 are shown in figure 7.

Walton area includes the Ft. Walton Beach area and Eglin Air Force Base at Niceville. The rate of growth of industry and population is accelerating. Pumpage from the Floridan aquifer for all uses is about 10.0 mgd (million gallons per day). As a result of continuing heavy pumping, water levels have declined in about a 640 square-mile area. The hydrograph of well Okaloosa 3 at Ft. Walton Beach, figure 8, shows a maximum decline of 98.3 feet from 18.5 feet above land surface in 1947 to 79.8 feet below land surface in 1964. In August 1936, the artesian water level was 46 feet above land-surface datum. During the period from August 1936 to July

INFORMATION CIRCULAR NO. 52 29 1964, the water level in well Okaloosa 3 declined 125 feet, from 46 feet above land surface to 79 feet below land surface. The areal extent of the decline in artesian levels in the vicinity of Ft. Walton Beach is shown by the net change of water levels map, figures 9 and 10. Water-level changes during 1951-62 are shown by figure 9. Changes of groundwater levels for the current period May 1962-64 are shown by figure 10. PANAMA CITY AREA The Panama City area includes 250 square miles in Bay County, including Tyndall Air Force Base. The Floridan aquifer supplies most of the water for municipal, industrial, and military needs in the area. Figure 11 shows total pumpage from the Panama City well fields at St. Andrews and Millville for the period 1944-64. Pumpage of ground water for municipal use declined from an average of 1,200 mgy (million gallons per year) in 1961-62 to an average of 860 mgy in 1963-64. To some extent, reduced pumpage by Panama City and a change in locale of source of water by the pulp industry allowed water levels to rise sharply during 1963-64. Instead of the usual fall and winter rise of 2 to 7 feet, water levels rose 24 feet from 78 feet to 54 feet below land surface from June 1963 through December 1964. The alteration of the pattern of fluctuations of water levels was probably also the result of above average annual rainfall in the area during 1964. The long-term trends and fluctuations of ground-water levels at Panama City are shown by the hydrograph of well Bay 7, figure 12. The decline of water level in well Bay 7 represents the maximum known decline in the area and is caused by pumping in nearby wells. In August 1936, the water level in well Bay 7 was about 36 feet below land surface, while in June 1963, it was about 78 feet below land surface, a maximum decline of 42 feet. NORTHERN AND NORTH-CENTRAL FLORIDA Northern and north-central Florida as used in this report extends from the Apalachicola River eastward to the Atlantic Ocean and from the Georgia line southward to the latitude of Ocala, figure 13, and includes 24 counties and parts of Levy Marion, and Volusia counties.

The area is primarily residential and only sparse light industry is located in this area. The principal water user, the City of Tallahassee, supplies water for municipal use to the most rapidly growing residential and educational complex in the Big Bend. Since 1945, annual municipal pumpage at Tallahassee has increased 365 percent from about 850 mgy to 3,100 mgy. Figure 14 shows pumpage during 1933-64 for the City of Tallahassee. Fluctuations of water levels in the Floridan aquifer at Tallahassee are shown by the hydrograph, figure 15, of well Leon 7, which shows a downward trend during 1960-63 and an upward trend in response to above average rainfall during 1964. The graph shows characteristic seasonal trends with high levels in the spring and low levels in the fall. Figure 16 shows water levels in well Leon 7 for the period 1945-64.

38 DIVISION OF GEOLOGY Figure 17. Graph of total yearly pumpage, City of Jacksonville. and location of observation wells for which hydrographs are given are shown in figure 20. The principal source of ground-water supply in western coastal and central peninsular Florida is the Floridan aquifer. In the eastern coastal area, the nonartesian shallow-sand aquifer is the chief source. Central Florida includes four rapidly growing centers of population and industry: the Tampa-St. Petersburg area, the Lakeland area, the Orlando-Cape Kennedy area, the Sarasota-Bradenton area. TAMPA-ST. PETERSBURG AREA This area, particularly in the vicinity of Tampa and St. Petersburg, is undergoing a rapid expansion in both industry and population. The long-term trends and fluctuations of ground-water levels in the Floridan aquifer in the Tampa-St. Petersburg area are shown in figure 21. The hydrographs show a similarity of waterlevel fluctuations in well Pasco 13 near Ehren and well Hillsborough 13 near Citrus Park, during the period 1945 through 1962. Drought conditions and increased pumping during 1961-64 caused water levels in Hillsborough 13 to decline to the lowest levels of record in 1964.

Near Ruskin, in southern Hillsborough County, water levels in well Hillsborough 30 declined to the lowest level of record in 1963, shown in figure 23. This decline is part of an extensive regional lowering of water levels which extends from southern Hillsborough County into Sarasota County. (See figure on page 54). Water levels in two Pinellas County wells, Pinellas 13 and 246, are shown in figure 23. No apparent trend is noted for Pinellas 13. However, a slight downward trend from 1946 through 1956 can be noted for Pinellas 246. This downward trend -was reversed during the latter part of 1956 and levels continued to rise through 1959 and were about average for the period of record 1963-64.

Long-term trends and fluctuations of ground-water levels in the Lakeland area are shown in figure 27. Water levels in the artesian aquifer, in southern Polk County, and in the shallow-sand aquifer, in southeastern Polk County and in central Highlands County, are shown in figure 28. The most prominent .features illustrated by the hydrographs in figure 28 are the fluctuation of water levels in the artesian aquifer and in the shallow-sand aquifer caused by the droughts of 1955-56 and 1961-62 and subsequent recovery of levels during post-drought periods. In southern Polk County at Frostproof, water levels declined about 11 feet in the artesian aquifer in well Polk 51 from January 1960 to May 1962. In central Highlands County near Sebring, levels declined nearly 6 feet in the nonartesian aquifer in well Highlands 10 during the same period. During 1962 ground-water levels rose sharply. However, in most wells, the recovery of levels in 1963-64 did not exceed those of 1960. Water levels during 1964 ranged from 1.5 feet below 1960 highest levels in the artesian aquifer at Frostproof to 5.1 feet lower than 1960 levels in the nonartesian aquifer in central Highlands County. In southern Osceola and southeastern Highlands counties, 1963-64 water levels in the nonartesian aquifer ranged from 1 foot lower in wells Osceola 183 and Okeechobee 3 to 2.4 feet lower than 1960 levels in well Highlands 13.

Levels declined to a record-low level of about 2 feet above mean sea level in the spring of 1962 and 1963. The declines during 1961-63 were caused, in part, by increased pumping in the Stuart well field. Although pumpage increased during 1964, water levels rose in response to above average rainfall.

64 DIVISION OF GEOLOGY MIAMI AREA The Miami area includes Broward and Dade counties and is the most populous area in the State. The principal source of water supply is the Biscayne aquifer, the extent of which is shown on figure 1. The locations of selected observation wells in the Miami area for which hydrographs are given, are shown by figure 34. Water-level observations were made as early as -1933 near Homestead in well Dade S196A. Long-term record of water-level fluctuations at Homestead are shown in figure 41. Figure 43 shows trends of water levels and rainfall recorded at Homestead Experimental Station 1960-64. Except for the relatively narrow coastal strip, most of the Miami area is occupied by the Everglades. Fluctuations of groundwater levels in the Everglades are shown by hydrographs of wells Dade G72, G596, G618, and G620, figures 44 and 45. Fluctuations of ground-water levels in the Biscayne aquifer in the vicinity of Miami are illustrated by hydrographs of wells Dade G10 about 5 miles west of Miami, Dade S19 at Miami Springs (fig. 44), and well Dade F179 at Miami (fig. 41). The water level in well Dade S19 is affected by pumping in the municipal well field of the City of Miami. In the Miami area, as in other coastal areas, the presence of salty water in an aquifer is signalled by high chloride content of the ground water. The seaward reaches of the Biscayne Aquifer contain sea water and some encroachment of sea water into the aquifer has occurred through the years. Water control measures have checked the encroachment and as a result a freshening of the ground water has occurred in some areas. Generally, chloride content of ground water decreased in the Miami area and in southern coastal Dade County during 1963-64. Figure 42 shows fluctuations of chloride content of ground water in the Biscayne aquifer in the Miami area. Chloride content of ground water in well Dade F64 in Miami decreased to the lowest of record since 1947. During 1963-64, chlorides ranged from 250 to 550 ppm in this well. Chloride content of ground water in the Biscayne aquifer ranged from 400 to 700 ppm in well F296 on the coast north of Miami. Chloride content was generally lower during 1963-64 than during 1962. Near the eastern edge of the Miami well field area in Miami Springs, chloride content decreased from 900

During 1963-64, chloride content decreased to the lowest of record in this well. In southern coastal Dade County, chloride content of ground water in the Biscayne aquifer generally decreased or remained at low concentrations in several areas during 1963-64. Chloride content decreased to less than 500 ppm in well Dade S529 on the coast and that of well Dade G212 southeast of Homestead remained at less than 200 ppm during 1963-64. In sharp contrast, the chloride content in well Dade G469 near the coast south of Miami increased from about 20 ppm in 1961 to about 8600 ppm in 1964 as a result of new canal construction in that area. In the Miami area, as in other coastal areas, the contamination of the Biscayne aquifer by the encroachment of salty water is an ever-present problem. Through intensive practice of water control the problem of prevention of salt-water contamination has been solved. In many areas where contamination existed the situation
