WATER LEVELS IN
ARTESIAN AND NONARTESIAN
AQUIFERS OF FLORIDA, 1969-70.
By
Henry G. Healy
INTRODUCTION
This report summarizes the trends and fluctuations of ground-water levels in wells tapping the principal aquifers in Florida during 1969-70 and includes the following: (1) hydrographs of 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.
The "Index to Water Resources Data Collection Stations in Florida, 1961" Florida Geological Survey Special Publication No. 11, lists the observation wells for which records are available. The index was prepared by the U.S. Geological Survey in cooperation with the Florida Geological Survey, (now the Bureau of Geology, Florida Department of Natural Resources) and includes the location, name of aquifer, and type and period of records available for 3,656 observation wells.
Since World War II, and particularly during the last decade, the demand for fresh water for industrial, municipal, and agricultural uses in Florida has increased yearly. Although ground-water supplies have been adequate for the increased demand in most areas, water levels have declined appreciably in some. 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 developing from increasing demands, the present supplies of ground water must be properly appraised before they can be effectively utilized. Records of trends and fluctuations of ground water have long formed a basis for such an appraisal.
The principal objective of the investigations of the Water Resources Division of the U. S. Geological Survey is to appraise and to evaluate the
" 1




2 BUREAU OF GEOLOGY
nation's water resources. Although many types of ground-water investigations are carried out on a statewide basis throughout the nation, the collection and compilation of hydrologic data constitute an important part of the water-resource studies.
Objectives of the hydrologic data-collection program in Florida include: the evaluation of available ground-water supplies; the prediction of trends of water levels; and the delineation of present or potential areas of detrimentally high or low ground-water levels. Water levels are used to determine 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 basic research. The hydrologic-data program provides the foundation information necessary for the successful and meaningful accomplishment of water-resource investigations.
The hydrologic data-collection program of the U.S. Geological Survey is part of the cooperative investigations of the water resources of Florida in cooperation with the Division of Geology, Florida Board of Conservation, and other state and local agencies and municipalities The observationwell network in 1970 included about 1,100 wells in the 67 counties of the state. Figure 1 shows the locations of selected observation wells in the statewide network. Table 1 (see appendix) lists data on 364 observation wells selected from the statewide network of wells.
Thy hydrologic-data program consists of the collection, tabulation, and 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 Watr-Supply Papers.
Information pertinent to ground water is also published in interpretative reports of investigations published by the Florida Bureau of Geology and the U.S. Geological Survey. Data collected during an investigation and prior to publication are available from the District Chief, U.S. Geological Survey, 903 W. Tennessee Street, Tallahassee, Florida 32304.
The water-level data used in this report represent measurements taken from automatic water-stage recorder charts, pressure gages, and made manually by tape. Generally, measurements made by tape and automatic 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. Measurements for January, May, and September are used if stage recorder or bimonthly periodic water-level measurements are available; January and May measurements are used if the frequency of measurement is semiannual. May measurements are used if the frequency of measurement is annual.
Table I (appendix) summarizes well data and water-level information for the several aquifers. Well data include the aquifer name, depth of well and casing, the year that the record began, and the frequency of water-level measurement. Water-level information includes the highest and lowest May

or June measurements of record prior to 1969, the highest May or June measurement for the biennial period of the report, and the biennial change. Generally, highest and lowest levels are highest daily levels iftaken from recorder charts. The months May or June are used because records are available for these months for most of the wells. Also, during these two months, ground-water levels are lowest in most areas and measurements during that period are the most reliable in comparing water-level changes from year to year. The annual change of water levels in the Florida aquifer, May 1969May 1971 is illustrated on figure 2.
WELL-NUMBERING SYSTEMS
Four well-numbering systems are used in this report: serially by counties, e.g. Hendry 7, and three grid-coordinate systems of seven, nine, and

sixteen digits. Frequently, especially with older wells more than one system of numbers have been assigned. In table 1, for example, well Bay 7 is shown as 7(010-541-1) in addition to having a sixteen digit number. The use of different numbers for each well is necessary as this affords a tie-in with water level data published previously under the different well numbers.
The grid-coordinate well-numbering systems in Florida are derived from latitude and longitude coordinates.
The seven-digit well number is a composite of three numbers separated by hyphens: the first is composed of the last digit of the degree and the two digits of the minute tlha-tdefine the latitude on the south side of the 1-minute quadrangle; the second number is composed of the last digit of the de,gree 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 orderin which the well was :inventbried in the 1-minute quadrangle. For example,




6 BUREAU OF GEOLOGY
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 first two series of three numbers each of the nine-digit well number denotes latitude and longitude as explained under the seven-digit well number. The third series of numbers in the nine-digit well number gives the location of the well in a 1-minute rectangle which has been divided into quarters, sixteenths and sixty-fourths. The first digit of the series locates the well within the quarter numbered 1, 2,3, and 4 in southwest and southeast. Similarly, the second digit locates the well within the quarter-quarter

The sixteen-digit well number consists of degrees, minutes, and seconds of latitude and longitude and a sequential number which indicates the number of the well in a 1-second square quadrangle. Figure 4 shows a schematic explanation of the sixteen-digit well numbering system.
The numbers for some wells listed in table 1 have 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

PRINCIPAL AQUIFERS
Ground-water supplies for agricultural, industrial, and municipal uses in Florida are obtained 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. Highly mineralized water precludes the use of the Floridan Aquifer as a

source of potable water in some coastal areas and in most of southern Florida. In these areas, shallow artesian and nonartesian aquifers are the source of supply. Areas of artesian flow and the potentiometric surface of the Floridan Aquifer is illustrated by figure 5.
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 supplies of ground water for industries and municipalities. The aquifer extends beneath all of Escambia and Santa Rosa counties and part of western Okaloosa County.
This report of ground-water conditions has been divided into four sections as follows: (1) northwestern Florida; (2) northern, northeastern, and north-central Florida, (3) central Florida; and (4) southern and southeastern coastal Florida.
NORTHWESTERN FLORIDA
The northwestern section includes the Florida panhandle extending from the Apalachicola River westward to the Florida-Alabama line, as shown in figure 6.

The principal sources of ground-water supply in this section are the sand-and-gravel aquifer in Escambia and Santa Rose counties and the Floridan Aquifer in Okaloosa County eastward to the Apalachicola River. Minor supplies of ground water are obtained from shallow nonartesian aquifers.
Pensacola, Ft. Walton Beach, and Panama City are growing rapidly in industry and population.
PENSACOLA AREA
The Pensacola area includes Escambia and Santa Rosa counties, and

INFORMATION CIRCULAR NO. 73 11
like many areas in the State, is undergoing rapid economic development accompanied by increasing use of water by industry and municipalities. For example, figure 7 shows that the total 1970 pumpage for the city of Pensacola was about four times that of 1945. Total yearly municipal pumpage at Pensacola increased from 1.470 mgy (million gallons per year) in 1945 to 6,313 mgy in 1970 (figure 7).
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 6 shows locations of observation wells selected from the hydrologic-data network for which hydrographs are given in this report, and table 1 (appendix) presents data on 13 wells in Escambia County and 4 wells in Santa Rosa County. Figure 8 shows fluctuations and long-term trends of artesian water levels in the sand-and-gravel aquifer in the Pensacola area from 1945 through 1970.
Hydrographs (fig. 8) and table 1 (appendix) show that water levels declined in some areas during 1969, but rose in most areas in 1970 in central and southern Escambia County. In those areas affected by pumping, 1970 water levels ranged from less than 1 foot to 23 feet lower than those of 1969. End-of-year levels near Cantonment and well Escambia 45 rose less than 1 foot above 1969 levels. Water levels near Ensley and well Escambia 46 rose nearly 4 feet above those of 1969.
In the coastal area at Pensacola, at the end of 1970 the artesian water level in well Escambia 62 was less than 1 foot above that of January 1969. Trends and fluctuations of artesian levels in well Escambia 62 and departures from monthly average rainfall at Pensacola, 1969-1970, are shown on figure 9.
FT. WALTON BEACH AREA
The Ft. Walton area includes the Ft. Walton Beach area and Eglin Air Force Base. 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 since 1936.
The hydrographs of well Okaloosa 3 at Fort Walton Beach and wells Okaloosa 25 and 31 about 15 miles north of Fort Walton Beach show the decline of ground-water levels in a broad area as shown in figure 10. From August 1936 to May 1970 the level in well Okaloosa 3 declined 110.8 feet, from 46 feet above land surface in 1936 to 65.2 feet below. The areas where, in the vicinity of Fort Walton Beach, decline in artesian level has occurred is shown on figures 11 and 12.
The net change of water level from 1951-68 is shown in figure 11 and that from 1968-70 in figure 12.

NORTHERN, NORTHEASTERN, AND NORTH-CENTRAL
FLORIDA
The northern, northeastern, and north-central Florida section extends from the Apalachicola River eastward to the Atlantic Ocean and from the Georgia line southward to the latitude of Ocala, and includes 24 counties and parts of Levy, Marion, and Volusia counties, as shown on figure 15. This section includes two areas undergoing rapid expansion in population and industry theTallahassee area and the Jacksonville-Fernandina area.
The Floridan Aquifer is the principal source of ground-water supply in coastal areas in eastern St. Johns, Flagler, and Volusia Counties. Another important source of water in these areas is a shallow, nonartesian, sandand-shell aquifer.
TALLAHASSEE AREA
The Tallahassee area includes central Leon County and the city of Tallahassee. The area is primarily residential with only sparse light industry.
The principal water user, the city of Tallahassee, supplies water for municipal use to the most rapidly growing residential and educational complex in northern Florida. Since 1945, annual municipal pumpage at Tallahassee has increased about 420 percent, from 850 mgy to 4,393 mgy in 1970. Figure 16 shows pumpage for the city of Tallahassee during 1945-70.

Figure 16 Total yearly pumpage, city of Tallahassee. Water-level fluctuations in the Floridan Aquifer at Tallahassee are shown by the hydrograph of well Leon 7, figure 17. The downward trend of levels in 1967-68 reversed in 1969, and levels rose about 2.5 feet in well Leon 7 at Tallahassee from the beginning of 1969 to the end of 1970. The longterm record for well Leon 7 at Tallahassee, as shown in figure 18, shows no discernible long-term downward trend for the entire period of record.
The short-term trends correspond closely to the areal rainfall pattern: levels declined to the lowest of record during the 1954-56 drought. During 1969-70 levels. rose nearly .6 feet from the 1969 June low to a 1970 April high level, then generally declined during the rest of 1970. At the end of

The long-term trends and fluctuations of ground-water levels in the Floridan Aquifer in the Tampa-St. Petersburg area are shown in figure 23. Increased pumping during 1969-70 caused water levels in Hillsborough 13 to decline to the lowest levels of record in 1970. For comparison, fluctuations of levels in an area not affected by pumping are shown on the graph of well Pasco 13. Departures from monthly rainfall recorded at Tampa and the fluctuations of the water level in well Hillsborough 13 for 1969-70 are shown in figure 24. Near Ruskin, in southern Hillsborough County, water levels in well Hillsborough 30 declined to the lowest level of record in early 1968, as shown in figure 25, then rose in later 1968-and continued about average during 1969-70.

No apparent trend is noted for levels in Pinellas County well Pinellas 13 during the period of record (figure 25). For Pinellas 246, however, a slight downward trend from 1946 through 1956 is noted. This downward trend was reversed during the latter part of 1956 and levels continued to rise

through 1959. During 1959-68 the downward trend of levels is again evident in well Pinellas 246. During 1969-70, this trend was reversed, and levels rose to about average.
Chloride content of water from two wells that tap the Floridan Aquifer in Pinellas County are shown in figure 26.
At Dunedin, the chloride content of well Pinellas 166 decreased during 1969-70 and reached the lowest concentration since 1966. During 196970, the chloride content ranged from 575 mg/1 (milligrams per liter) in January 1969 to 122 mg/1 in May 1970.
At Bay Pines, during 1969-70, the chloride content in water from well Pinellas 592 fluctuated from 625 mg/1 in January 1969 to 1750 mg/1 during May 1969. During 1970, chloride ranged from 860 mg/1 in Januarv to 1600 mg/1 in May 1970. Generally, chloride concentration in water from both wells had a narrower range of fluctuations in 1969-70 than 1967-68.
LAKELAND AREA
In the Lakeland area, ground water is being pumped at an increasing rate commensurate with the economic growth of the area. Since 1945, municipal pumpage increased from about 1,250 to 5,237 mgy. Annual pumpage reached a maximum of 5,300 million gallons in 1967, decreased to 4,486 million gallons in 1969, as shown on figure 27, and then increased to 5,237 million gallons in 1970.
Fluctuations of water levels in the Floridan Aquifer in the vicinity of Lakeland are shown in figure 28. The level in well Polk 45 remained about average during 1969, but declined about 17 feet during early 1970, then rose during June, July and August.
In many parts of northern Polk County, water levels declined to new record lows during 1960-62, rose sharply in 1963, then declined to still lower levels in 1965, 1967, and 1968. The level in well Polk 45 tapping the Floridan Aquifer declined nearly 31 feet during 1964-68 in the heavily pumped area south of Lakeland. The artesian level in well Polk 44 near Davenport in northeastern Polk County rose 2.0 feet during 1969 then declined an equal amount in 1970. Levels in well Polk 47 in the nonartesian aquifer near Davenport rose 2.5 feet to the highest level of record since 1949. The trend of levels in artesian and nonartesian aquifers was generally slightly downward in comparison with sharp declines of 1967-68, which were primarily caused by deficient rainfall and increased pumping in northern Polk County during 1967 and early 1968. At Lakeland rainfall was deficient during 1961 through early 1968. Rainfall ranged from 1.6 inches above average in 1969 to 4.8 inches below average in 1970. Long-

Water levels in the artesian Hawthorn Aquifer and in the shallow sand nonartesian aquifer in southeastern Polk County and central Highlands County are shown in figure 30.
The decline of the nonartesian water levels caused by the droughts of 1954-56 and 1961-62 and the well-defined downward trend of artesian levels in the Hawthorn Aquifer are the prominent features illustrated by the hydrographs in figure 30.

Water levels in the shallow sand nonartesian aquifer generally rose during 1969 then declined in 1970, as shown on hydrographs of well Polk 49 near Frostproof, and well Highlands 10 near Sebring. During 1970, levels in both wells rose to the highest of record since 1948. In sharp contrast, the level in well Polk 51 in the Hawthorn Aquifer near Frostproof declined sharply during 1970, but by the end of 1970 had risen nearly to 1968 levels. Figure 31 shows fluctuations of water levels in the shallow sand nonartesian aquifer in southeastern Highland county, Osceola and Okeechobee counties.

During 1970 the municipal pumpage at Orlando and Winter Park increased markedly. At Orlando, total yearly pumpage increased 411 percent during 1945-70 and at Winter Park 377 percent during 1951-70. At the Cocoa well field, the decrease in total annual pumpage during 1969-70 reflects to a degree the diminished activity at Cape Kennedy.

are agricultural-truck and citrus farming and stock raising. The coastal section, however, is rapidly developing as a retirement and year-round tourist center.
The hydrograph of observation well Sarasota 9 tapping the Floridan Aquifer shows a well-defined decline. The water level declined 26.07 feet, from 5.20 feet above land surface in March 1931, the highest recorded level, to a record low of 20.87 feet below land surface in May 1968. During 1969-70 the level declined seasonally and fluctuated in response to rainfall and areal pumping.
The hydrograph of well Sarasota 9 shows the decline is continuing and that the range of annual fluctuations reached a maximum during 1967-68. The regional extent of the decline is shown by hydrographs of well Hillsborough 30 (fig. 25) and of well Sarasota 9, as shown in figure 38.
SOUTHERN FLORIDA
The southern Florida section includes all counties south of a line through DeSoto County arid covers an area of about 17,500 square miles. The region and locations of selected observation wells for which hydrographs are presented are shown on figure 39.
In the coastal areas of Martin and Palm Beach Counties and in southwestern coastal Florida and inland areas, nonartesian shallow-sand aquifers are the chief sources of supply. In Broward and Dade Counties, the Biscayne Aquifer is the principal source.

52 BUREAU OF GEOLOGY
The principal source of water supply in the Stuart-West Palm Beach area is the nonartesian shallow-sand aquifer. The hydrograph ofwell Martin 147 at Stuart (fig. 41) shows the downward trend of nonartesian water levels. Levels declined to a record low of about 2 feet above mean sea level in the spring of 1962, 1963, and 1965. During 1968 and 1970 levels declined below I foot above mean sea level, and at the end of 1970 the level declined to nearly m.nean sea level. The declines were caused in part by increased pumping in the Stuart well field and rainfall deficiency late in 1970. Figure 43 shows trends of water levels and departures from normal monthly precipitation recorded at Stuart, 1965-70.
The chief source of water supply in southern Palm Beach, Broward, and Dade Counties is the Biscayne Aquifer. Figure 44 shows the trends and fluctuations of end-of-month wdter level in well Palm Beach 88 and departures from normal monthly precipitation data at West Palm Beach. Fluctuations of water levels for several selected wells are shown in figures 45 and 46.
FT. LAUDERDALE AREA
The Ft. Lauderdale area includes the populous coastal part of Broward County, extending from the Deerfield-Boca Raton area in the northern part of the county to the Hollywood area in the southern part of the county. Long-term downward trends of water levels in the Biscayne Aquifer in and adjacent to the Ft. Lauderdale area are shown by the hydrograph of well Broward S329 at Ft. Lauderdale (fig. 46).
Adjacent to the coast and along tidal canals the Biscayne Aquifer contains salty water. Figure 47 shows graphs of the choloride content of water in wells Broward G515, G820A, and S830, all in the vicinity of the Ft. Lauderdale Dixie well field. The chloride content of water in well Broward G515 is increased slightly over 500 mg/l (milligrams per liter) to 750 mg/1 in 1955, then decreased to about 700 mg/l in 1968. During December 1970 chloride content increased to a record high of 870 mg/1. The chloride content of water from well Broward G820A decreased from 85 mg/1 in 1956 to 15 mg/1 in 1960, then gradually increased to 33 mg/1 in 1967. Chloride content ranged from 34 mg/1 in October 1969 to 24 mg/1 in October 1970. The chloride content of water in well Broward S830 decreased from about 3,700 mg/1 in 1947 to 50 mg/i in 1958, then gradually increased to 2,750 mg/i1 in 1969, then decreased sharply to 1,760 mg/1 late in 1970.

INFORMATION CIRCULAR NO. 73 59
Declines, which ranged from less than 1 foot to nearly 2 feet, were the result of rainfall deficiencies in the latter half of 1970.
In the vicinity of Miami, fluctuations of water levels in the Biscayne Aquifer are illustrated by hydrographs of wells Dade G10 west of Miami, Dade S19 at Miami Springs (fig. 51), and well Dade F179 at Miami (fig. 46). The water level in well Dade S19 is affected by pumping in the city of Miami municipal well field. Total yearly pumpage for Miami is shown in figure 54.
Generally, chloride content of water from the Biscayne Aquifer decreased in most areas of Dade County during 1969-70. In northern Dade County, chloride content of water from well Dade S68 at Miami Springs well field near Miami decreased from 50 to 29 mg/1. Chloride content in water from well Dade D151, North Miami, decreased from 105 to 6 mg/1 in the fall of 1969, then increased to 28 mg/1 in January 1970 (fig. 53). The chloride content in water from well F296 remained nearly the same as in 1969-70 (fig. 47).
In water from wells in most of southern coastal Dade County, chloride content generally remained low during 1969-70. Chloride content in water from well Dade S529 remained about the same from 1968 through the period of record (fig. 53).
In the Miami area, as in other coastal areas, the presence of salt water in an aquifer is signalled by high chloride content of the ground water. Sea water is contained in the seaward reaches of the Biscayne Aquifer, and some sea water has encroached into ihe aquifer through the years.
In the Miami area, the contamination of the Biscayne Aquifer by the encroachment of salt water is an ever-present problem. In some places through intensive practice of water control, salt-water contamination has beenT prevented. In other areas, where contamination already existed, the situation has been relieved by water control. The effectiveness of the method of control is graphically illustrated by the chloride graph of well Dade S529, as shown in figure 53. Chloride content of water from this well decreased from nearly 3,000 mg/1 in 1947 to less than 500 mg/1 in 1964.

Table 1. Summary of well data and water levels in selected observation wells.
Well number: Well numbers are based on latitudinal and longitudinal numbering system e.g., 293620N0813620.1.
Local well numbers, included below the 16-digit well number, are given where the well has been reported previously in a publication under that number. Letters prefixed to well numbers in Broward and Dade Counties; G, Geological Survey well; S, supply well; F, fire well; letter suffix A, shallow well adjacent to deep
well or a replacement well.
Aquifer: B, Biscayne, F, Floridan, G, sand-and-gravel; H, Hawthorne, M, Miocene sand, NA, nonartesian, O, Oldsmar limestone; P, Pleistocene sand; S, shallow
sand; T, Tamiami Formation.
Depth of well: Measured unless otherwise noted. R, reported depth.
Frequency of measurement: Refers to current biennium. A, annually; B, bimonthly; C, continuous; M, monthly; S, semiannually, W, weekly.
Water level: To hundredth of a foot if measured by wet-tape method or taken from recorder chart; to nearest tenth of a foot if measured by pressure gage or airline.
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; S, water level affected by seasonal or regional pumping; T, water levels affected by ocean
tides; X, well in use.

WATER LEVELS IN ARTESIAN AND NONARTESIAN AQUIFERS OF FLORIDA, 1969-70. By Henry G. Healy INTRODUCTION This report summarizes the trends and fluctuations of ground-water levels in wells tapping the principal aquifers in Florida during 1969-70 and includes the following: (1) hydrographs of 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. The "Index to Water Resources Data Collection Stations in Florida, 1961" Florida Geological Survey Special Publication No. 11, lists the observation wells for which records are available. The index was prepared by the U.S. Geological Survey in cooperation with the Florida Geological Survey, (now the Bureau of Geology, Florida Department of Natural Resources) and includes the location, name of aquifer, and type and period of records available for 3,656 observation wells. Since World War II, and particularly during the last decade, the demand for fresh water for industrial, municipal, and agricultural uses in Florida has increased yearly. Although ground-water supplies have been adequate for the increased demand in most areas, water levels have declined appreciably in some. 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 developing from increasing demands, the present supplies of ground water must be properly appraised before they can be effectively utilized. Records of trends and fluctuations of ground water have long formed a basis for such an appraisal. The principal objective of the investigations of the Water Resources Division of the U. S. Geological Survey is to appraise and to evaluate the " ' ' 1 "

2 BUREAU OF GEOLOGY nation's water resources. Although many types of ground-water investigations are carried out on a statewide basis throughout the nation, the collection and compilation of hydrologic data constitute an important part of the water-resource studies. Objectives of the hydrologic data-collection program in Florida include: the evaluation of available ground-water supplies; the prediction of trends of water levels; and the delineation of present or potential areas of detrimentally high or low ground-water levels. Water levels are used to determine 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 basic research. The hydrologic-data program provides the foundation information necessary for the successful and meaningful accomplishment of water-resource investigations. The hydrologic data-collection program of the U.S. Geological Survey is part of the cooperative investigations of the water resources of Florida in cooperation with the Division of Geology, Florida Board of Conservation, and other state and local agencies and municipalities. The observationwell network in 1970 included about 1,100 wells in the 67 counties of the state. Figure 1 shows the locations of selected observation wells in the statewide network. Table 1 (see appendix) lists data on 364 observation wells selected from the statewide network of wells. Thy hydrologic-data program consists of the collection, tabulation, and 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 Bureau of Geology and the U.S. Geological Survey. Data collected during an investigation and prior to publication are available from the District Chief, U.S. Geological Survey, 903 W. Tennessee Street, Tallahassee, Florida 32304. The water-level data used in this report represent measurements taken from automatic water-stage recorder charts, pressure gages, and made manually by tape. Generally, measurements made by tape and automatic 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. Measurements for January, May, and September are used if stage recorder or bimonthly periodic water-level measurements are available; January and May measurements are used if the frequency of measurement is semiannual. May measurements are used if the frequency of measurement is annual. Table I (appendix) summarizes well data and water-level information for the several aquifers. Well data include the aquifer name, depth of well and casing, the year that the record began, and the frequency of water-level measurement. Water-level information includes the highest and lowest May

Generally, highest and lowest levels are highest daily levels if taken from recorder charts. The months May or June are used because records are available for these months for most of the wells. Also, during these two months, ground-water levels are lowest in most areas and measurements during that period are the most reliable in comparing water-level changes from year to year. The annual change of water levels in the Florida aquifer, May. 1969Mav 1971 is illustrated on figure 2.

Frequently, especially with older wells more than one system of numbers have been assigned. In table 1, for example, well Bay 7 is shown as 7(010-541-1) in addition to having a sixteen digit number. The use of different numbers for each well is necessary as this affords a tie-in with water level data published previously under the different well numbers. The grid-coordinate well-numbering systems in Florida are derived from latitude and longitude coordinates. The seven-digit well number is a composite of three numbers separated by hyphens: the first is composed of the last digit of the degree and the two digits of the minute thaTdefine 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.

The first two series of three numbers each of the nine-digit well number denotes latitude and longitude as explained under the seven-digit well number. The third series of numbers in the nine-digit well number gives the location of the well in a 1-minute rectangle which has been divided into quarters, sixteenths and sixty-fourths. The first digit of the series locates the well within the quarter numbered 1, 2,3, and 4 in southwest and southeast.

The locations of wells with seven and nine digit numbers are diagrammatically shown in figure 3. The sixteen-digit well number consists of degrees, minutes, and seconds of latitude and longitude and a sequential number which indicates the number of the well in a 1-second square quadrangle. Figure 4 shows a schematic explanation of the sixteen-digit well numbering system. The numbers for some wells listed in table 1 have 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

PRINCIPAL AQUIFERS Ground-water supplies for agricultural, industrial, and municipal uses in Florida are obtained 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.

Areas of artesian flow and the potentiometric surface of the Floridan Aquifer is illustrated by figure 5. 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 supplies of ground water for industries and municipalities. The aquifer extends beneath all of Escambia and Santa Rosa counties and part of western Okaloosa County. This report of ground-water conditions has been divided into four sections as follows: (1) northwestern Florida; (2) northern, northeastern, and north-central Florida, (3) central Florida; and (4) southern and southeastern coastal Florida. NORTHWESTERN FLORIDA The northwestern section includes the Florida panhandle extending from the Apalachicola River westward to the Florida-Alabama line, as shown in figure 6.

For example, figure 7 shows that the total 1970 pumpage for the city of Pensacola was about four times that of 1945. Total yearly municipal pumpage at Pensacola increased from 1.470 mgy (million gallons per year) in 1945 to 6,313 mgy in 1970 (figure 7). 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 6 shows locations of observation wells selected from the hydrologic-data network for which hydrographs are given in this report, and table 1 (appendix) presents data on 13 wells in Escambia County and 4 wells in Santa Rosa County. Figure 8 shows fluctuations and long-term trends of artesian water levels in the sand-and-gravel aquifer in the Pensacola area from 1945 through 1970. Hydrographs (fig. 8) and table 1 (appendix) show that water levels declined in some areas during 1969, but rose in most areas in 1970 in central and southern Escambia County. In those areas affected by pumping, 1970 water levels ranged from less than 1 foot to 23 feet lower than those of 1969. End-of-year levels near Cantonment and well Escambia 45 rose less than 1 foot above 1969 levels. Water levels near Ensley and well Escambia 46 rose nearly 4 feet above those of 1969. In the coastal area at Pensacola, at the end of 1970 the artesian water level in well Escambia 62 was less than 1 foot above that of January 1969. Trends and fluctuations of artesian levels in well Escambia 62 and departures from monthly average rainfall at Pensacola, 1969-1970, are shown on figure 9. FT. WALTON BEACH AREA The Ft. Walton area includes the Ft. Walton Beach area and Eglin Air Force Base. 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 since 1936. The hydrographs of well Okaloosa 3 at Fort Walton Beach and wells Okaloosa 25 and 31 about 15 miles north of Fort Walton Beach show the decline of ground-water levels in a broad area as shown in figure 10. From August 1936 to May 1970 the level in well Okaloosa 3 declined 110.8 feet, from 46 feet above land surface in 1936 to 65.2 feet below. The areas where, in the vicinity of Fort Walton Beach, decline in artesian level has occurred is shown on figures 11 and 12. The net change of water level from 1951-68 is shown in figure 11 and that from 1968-70 in figure 12.

18 BUREAU OF GEOLOGY NORTHERN, NORTHEASTERN, AND NORTH-CENTRAL FLORIDA The northern, northeastern, and north-central Florida section extends from the Apalachicola River eastward to the Atlantic Ocean and from the Georgia line southward to the latitude of Ocala, and includes 24 counties and parts of Levy, Marion, and Volusia counties, as shown on figure 15. This section includes two areas undergoing rapid expansion in population and industry -theTallahassee area and the Jacksonville-Fernandina area. The Floridan Aquifer is the principal source of ground-water supply in coastal areas in eastern St. Johns, Flagler, and Volusia Counties. Another important source of water in these areas is a shallow, nonartesian, sandand-shell aquifer. TALLAHASSEE AREA The Tallahassee area includes central Leon County and the city of Tallahassee. The area is primarily residential with only sparse light industry. The principal water user, the city of Tallahassee, supplies water for municipal use to the most rapidly growing residential and educational complex in northern Florida. Since 1945, annual municipal pumpage at Tallahassee has increased about 420 percent, from 850 mgy to 4,393 mgy in 1970.

Increased pumping during 1969-70 caused water levels in Hillsborough 13 to decline to the lowest levels of record in 1970. For comparison, fluctuations of levels in an area not affected by pumping are shown on the graph of well Pasco 13. Departures from monthly rainfall recorded at Tampa and the fluctuations of the water level in well Hillsborough 13 for 1969-70 are shown in figure 24.

Chloride content of water from two wells that tap the Floridan Aquifer in Pinellas County are shown in figure 26. At Dunedin, the chloride content of well Pinellas 166 decreased during 1969-70 and reached the lowest concentration since 1966. During 196970, the chloride content ranged from 575 mg/1 (milligrams per liter) in January 1969 to 122 mg/1 in May 1970. At Bay Pines, during 1969-70, the chloride content in water from well Pinellas 592 fluctuated from 625 mg/1 in January 1969 to 1750 mg/1 during May 1969. During 1970, chloride ranged from 860 mg/1 in January to 1600 mg/1 in May 1970. Generally, chloride concentration in water from both wells had a narrower range of fluctuations in 1969-70 than 1967-68. LAKELAND AREA In the Lakeland area, ground water is being pumped at an increasing rate commensurate with the economic growth of the area. Since 1945, municipal pumpage increased from about 1,250 to 5,237 mgy. Annual pumpage reached a maximum of 5,300 million gallons in 1967, decreased to 4,486 million gallons in 1969, as shown on figure 27, and then increased to 5,237 million gallons in 1970. Fluctuations of water levels in the Floridan Aquifer in the vicinity of Lakeland are shown in figure 28. The level in well Polk 45 remained about average during 1969, but declined about 17 feet during early 1970, then rose during June, July and August. In many parts of northern Polk County, water levels declined to new record lows during 1960-62, rose sharply in 1963, then declined to still lower levels in 1965, 1967, and 1968. The level in well Polk 45 tapping the Floridan Aquifer declined nearly 31 feet during 1964-68 in the heavily pumped area south of Lakeland. The artesian level in well Polk 44 near Davenport in northeastern Polk County rose 2.0 feet during 1969 then declined an equal amount in 1970. Levels in well Polk 47 in the nonartesian aquifer near Davenport rose 2.5 feet to the highest level of record since 1949. The trend of levels in artesian and nonartesian aquifers was generally slightly downward in comparison with sharp declines of 1967-68, which were primarily caused by deficient rainfall and increased pumping in northern Polk County during 1967 and early 1968. At Lakeland rainfall was deficient during 1961 through early 1968. Rainfall ranged from 1.6 inches above average in 1969 to 4.8 inches below average in 1970. Long-

The hydrograph of observation well Sarasota 9 tapping the Floridan Aquifer shows a well-defined decline. The water level declined 26.07 feet, from 5.20 feet above land surface in March 1931, the highest recorded level, to a record low of 20.87 feet below land surface in May 1968. During 1969-70 the level declined seasonally and fluctuated in response to rainfall and areal pumping. The hydrograph of well Sarasota 9 shows the decline is continuing and that the range of annual fluctuations reached a maximum during 1967-68. The regional extent of the decline is shown by hydrographs of well Hillsborough 30 (fig. 25) and of well Sarasota 9, as shown in figure 38.

52 BUREAU OF GEOLOGY The principal source of water supply in the Stuart-West Palm Beach area is the nonartesian shallow-sand aquifer. The hydrograph of well Martin 147 at Stuart (fig. 41) shows the downward trend of nonartesian water levels. Levels declined to a record low of about 2 feet above mean sea level in the spring of 1962, 1963, and 1965. During 1968 and 1970 levels declined below 1 foot above mean sea level, and at the end of 1970 the level declined to nearly .nean sea level. The declines were caused in part by increased pumping in the Stuart well field and rainfall deficiency late in 1970. Figure 43 shows trends of water levels and departures from normal monthly precipitation recorded at Stuart, 1965-70. The chief source of water supply in southern Palm Beach, Broward, and Dade Counties is the Biscayne Aquifer. Figure 44 shows the trends and fluctuations of end-of-month wdter level in well Palm Beach 88 and departures from normal monthly precipitation data at West Palm Beach. Fluctuations of water levels for several selected wells are shown in figures 45 and 46. FT. LAUDERDALE AREA The Ft. Lauderdale area includes the populous coastal part of Broward County, extending from the Deerfield-Boca Raton area in the northern part of the county to the Hollywood area in the southern part of the county. Long-term downward trends of water levels in the Biscayne Aquifer in and adjacent to the Ft. Lauderdale area are shown by the hydrograph of well Broward S329 at Ft. Lauderdale (fig. 46). Adjacent to the coast and along tidal canals the Biscayne Aquifer contains salty water. Figure 47 shows graphs of the choloride content of water in wells Broward G515, G820A, and S830, all in the vicinity of the Ft. Lauderdale Dixie well field. The chloride content of water in well Broward G515 is increased slightly over 500 mgl/ (milligrams per liter) to 750 mg/1 in 1955, then decreased to about 700 mgll in 1968. During December 1970 chloride content increased to a record high of 870 mg/1. The chloride content of water from well Broward G820A decreased from 85 mg/1 in 1956 to 15 mg/1 in 1960, then gradually increased to 33 mg/1 in 1967. Chloride content ranged from 34 mg/1 in October 1969 to 24 mg/1 in October 1970. The chloride content of water in well Broward S830 decreased from about 3,700 mg/1 in 1947 to 50 mg/1 in 1958, then gradually increased to 2,750 mg/1 in 1969, then decreased sharply to 1,760 mg/1 late in 1970.

INFORMATION CIRCULAR NO. 73 59 Declines, which ranged from less than 1 foot to nearly 2 feet, were the result of rainfall deficiencies in the latter half of 1970. In the vicinity of Miami, fluctuations of water levels in the Biscayne Aquifer are illustrated by hydrographs of wells Dade G10 west of Miami, Dade S19 at Miami Springs (fig. 51), and well Dade F179 at Miami (fig. 46). The water level in well Dade S19 is affected by pumping in the city of Miami municipal well field. Total yearly pumpage for Miami is shown in figure 54. Generally, chloride content of water from the Biscayne Aquifer decreased in most areas of Dade County during 1969-70. In northern Dade County, chloride content of water from well Dade S68 at Miami Springs well field near Miami decreased from 50 to 29 mg/1. Chloride content in water from well Dade D151, North Miami, decreased from 105 to 6 mg/1 in the fall of 1969, then increased to 28 mg/1 in January 1970 (fig. 53). The chloride content in water from well F296 remained nearly the same as in 1969-70 (fig. 47). In water from wells in most of southern coastal Dade County, chloride content generally remained low during 1969-70. Chloride content in water from well Dade S529 remained about the same from 1968 through the period of record (fig. 53). In the Miami area, as in other coastal areas, the presence of salt water in an aquifer is signalled by high chloride content of the ground water. Sea water is contained in the seaward reaches of the Biscayne Aquifer, and some sea water has encroached into ihe aquifer through the years. In the Miami area, the contamination of the Biscayne Aquifer by the encroachment of salt water is an ever-present problem. In some places through intensive practice of water control, salt-water contamination has been; prevented. In other areas, where contamination already existed, the situation has been relieved by water control. The effectiveness of the method of control is graphically illustrated by the chloride graph of well Dade S529, as shown in figure 53. Chloride content of water from this well decreased from nearly 3,000 mg/1 in 1947 to less than 500 mg/1 in 1964.
