Healy INTRODUCTION This report summarizes the trends and fluctuations of ground-water levels in the principal aquifers in Florida during 1965-66 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. The index, prepared by the U. S. Geological Survey in cooperation with the Florida Geological Survey, (now the Bureau of Geology, Florida Department of Natural Resources), includes the location, aquifer, and type and period of records available for 3,600 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, 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 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 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 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 resources investigations. BUREAU OF GEOLOGY 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 Bureau of Geology, Florida Department of Natural Resources, and other state and local agencies and municipalities. The observation-well network in 1966 included about 850 ground-water data-collection stations in the 67 counties of the state. Figure 1 shows the locations of selected ground-water stations in the statewide network. Table 1 (see appendix) lists data on 307 observation wells selected from the statewide network of wells. 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 prior 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 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 most areas and records during that period constitute a base for comparison from year to year. Highest and lowest water levels of record prior to 1965 are given in the table. Generally, highest and lowest levels are highest daily levels if taken from recorder charts. The range of fluctuations for 1965 and 1966 are shown under "Annual range." WELL-NUMBERING SYSTEM Two well-numbering systems are used in this report; serially by counties or by a grid-coordinate system based on latitude and longitude of the well location. Frequently both numbers have been assigned to the 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.

Observation-well network, December 1966, and the extent of principal aquifers in Florida. BUREAU OF GEOLOGY 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 hot 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 I-minute quadrangle. For example, well number 835-105-1 is the first well inventoried in the I-minute quadrangle north of the 28035' parallel of latitude and west of the 8105'meridian of longitude. The location of well 835-105-1 is shown diagrammatically in figure 2. PRINCIPAL AQUIFERS Ground-water supplies for agricultural, industrial, and municipal uses 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. Areas of artesian flow and the potentiometric surface of the Floridan aquifer is illustrated by Figure 3. 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. 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. INFORMATION CIRCULAR NO. 61 Figure 2.

Potentiometric surface and areas of flow of the Floridan aquifer, in Florida, July 6-17, 1961 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 northwetern section includes the Florida Panhandle extending from the Apalachicola River westward to the Florida-Alabama line (Figure 4). 32 4 oilO' 0 9 1 r -N- ~.'l.'

Minor supplies of ground water are obtained from shallow nonartesian aquifers. The Pensacola, Ft. Walton Beach, and Panama City areas of the Florida panhandle are growing rapidly in industry and population. PENSACOLA AREA The Pensacola area includes Escambia and Santa Rosa counties, and like many others in the state, is undergoing rapid economic development accompanied by increasing use of water by industry and municipalities. Figure 5 shows that 1966 pumpage for the city of Pensacola was about six and one half times that of 1940. 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 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 4 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 1960 through 1966. Comparison of the hydrographs for the period of record reveals that while water levels at the end of 1966 declined in central and southern Escambia county, they remained above the low levels of the 1955-56 drought. Declines of artesian water levels in the sand-and-gravel aquifer ranged from nearly 30 feet in well Escambia 45 at Cantonment to about 10 feet in well Escambia 46 near Ensley during 1941-66. In the coastal area, at Pensacola, the artesian water level in well Escambia 62, at the end of 1966, was about the 1941 level. The trends and fluctuations of artesian ground-water levels in well Escambia 62 and departures from monthly average rainfall at Pensacola, 1965-66 are shown in figure 7. FT. WALTON 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. 5,000 4,200. 3BOOL _____ __________ 1,400 2,000__ **/m.. ,> A Figure 5.

In August 1936, the artesian water level was 46 feet above land-surface datum. During the period from August 1936 to July 1965, the water level in well Okaloosa 3 declined 134.5 feet, from 46 feet above land surface to 88.5 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.

INFORMATION CIRCULAR NO. 61 PANAMA CITY AREA The Panama City area includes 250 square miles in Bay County, including Tyndall Air Force Base. The Floridan aquifer-either indirectly or directly-supplies most of the water for municipal, industrial and military needs in the area. Springs from the Floridan aquifer supply Deer Point Reservoir the principal source of water for municipal use. Wells that tap the Floridan aquifer supply the paper and pulp industry and military needs at Tyndall Air Force Base. Figure 11 shows total pumpage from Panama City well fields at St. Andrews and Millville for 1944-66. 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 865 mgy in 1963-66. To some extent, reduced pumpage by Panama City wells and a change in the site of the source of water supply for the pulp industry allowed water levels to rise sharply during 1964-65. During this period, levels rose about 24 feet from 78 feet to 54 feet below land surface in well Bay 7 (figure 12). The rise of water levels in wells Walton 13 and Washington 4 during the same period indicates that the rise of water levels at Panama City reflected a major regional fluctuation or trend, as well as a reduction of pumping. NORTHERN AND NORTH-CENTRAL FLORIDA The northern 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, figure 13, and includes 24 counties and parts of Levy, Marion, and Volusia counties. 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, sand-and-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 nearly 430 percent from 850 mgy to about 3,650 mgy. Figure 14 shows pumpage for the City of Tallahassee during 1933-66. Water-level fluctuations in the Floridan aquifer at Tallahassee are shown by the hydrograph of well Leon 7, figure 15. The upward trend of levels of 1964 was continued into 1965-because of above average rainfall during that year. so z S o jjl2 Z0 Figure 11. Total yearly pumpage, Panama City, Florida.

Total municipal and industrial pumpage at Jacksonville in 1966 was about 21, 00 mgy. Figure 17 shows total yearly Jacksonville municipal pumpage 1921 through 1966. Trends and seasonal regional fluctuations of ground-water levels in the area are shown in figure 18. Ground-water levels, after a sharp rise in 1964 from record 1963 low levels, remained about the same during 1965-66 in well Duval 164 near Mayport and in well Nassau 12 near Fernandina in the coastal areas (figure 16). In contrast, levels at Jacksonville and inland at Callahan declined slightly during 1965-66. Declines of about 3 feet were recorded in well Duval 122 at Jacksonville and in well Nassau 51 at Callahan. Changes in water levels in the Floridan aquifer in the Ferandian-Jacksonville area are shown in Figure 19. CENTRAL FLORIDA Central Florida includes 20 counties and covers about 18,000 square miles. The extent of this section 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, while in the eastern coastal area the nonartesian shallow-sand aquifer is the chief source of water supply. In central peninsular Florida, levels in well Marion 5 near Ocala and in well Putnam 29 at Palatka remained about the same in 1965-66 after rising about 6 feet near Ocala and 4 feet at Palatka during 1963-64. Central Florida includes four rapidly growing centers of population and industry: the Tampa-St. Petersburg area, the Lakeland area, the Orlando-Cape Kennedy area, and 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. Persistent drought conditions and increased pumping during 1965-66 caused water levels in illsborough 13 to decline to the lowest levels of record in 1966. Rainfall recorded at Tampa and the fluctuations of the water level in well Hillsborough 13 for the period 1965-66 are shown in figure 22. Near Ruskin, in southern Bilsborough County, water levels in well Hillsborough 30 declined to the lowest level of record in 1965 (figure 23). This decline is part of an extensive regional lowering of water levels which extends from southern Hillsborough County into Manatee and Sarasota counties. (See figure 34.) Water levels in two Pinellas County wells, Pinellas 13 and 246, are shown in figure 23. No apparent trend is noted for Pinellas 13.

LAKELAND AREA Ground-water pumpage is keeping apace with the economic development and growth of the Lakeland area. Municipal pumpage increased about 264 percent during 1945-66. From 1945 through 1955 pumpage increased 83 percent with an average increase of 113 mgy. During 1956 through 1966 pumpage increased about 98 percent with an average rate of increase of 206 mgy. Figure 25 shows the total yearly municipal pumpage at Lakeland for 1928-66. The marked decline of water levels in the Floridan aquifer in the vicinity of Lakeland is shown in figure 26. A maximum decline of about 20 feet in well Polk 45 occurred during October 1960 through May 1962. During 1964-65, the decline was resumed with levels falling to the lowest of record in 1965.

CAPE KENNEDY AREA One of the most rapidly growing areas in the state is the Cape Kennedy area, which includes the cities of Cocoa, Cocoa Beach, and Titusville in Brevard County. In this area, water in the Floridan aquifer is generally brackish and is used primarily for irrigation. Water-level fluctuations in eastern coastal Florida in Brevard, Indian River and St. Lucie counties are shown in figure 33. Hydrographs of wells in Brevard County generally show a long-term downward trend of artesian levels in the Floridan aquifer. From 1946 through 1965 artesian levels have declined about 7 feet in well Brevard 79 in northern Brevard County about 28 miles northwest of Cape Kennedy and about 14 feet in well Brevard 148 at Cocoa. Water levels in both wells declined to new record lows during 1965, then rose in 1966 to about 1963-64 levels. Increased water use and deficiency of rainfall contributed to the sharp decline of water levels in Brevard County in 1965. Annual rainfall in 1965 at Titusville was 8.69 inches below normal.

Levels did decline to the lowest May level since May 1961 in well St. Lucie 42 (figure 33). In 1966, rainfall was 14.58 inches above normal at Titusville. SARASOTA-BRADENTON AREA The Sarasota-Bradenton area includes Manatee and Sarasota counties in southwestern coastal Florida. Principal economic activities in the area are agricultural-truck and citrus farming and stock raising. The coastal section, however, is rapidly developing as a retirement and year-round tourist center. Figure 34 shows trends and fluctuations of water levels in observation wells Manatee 92 and Sarasota 9. Hydrographs of both wells show well-defined declines of artesian water levels in the Floridan aquifer. Levels in well Manatee 92 have declined about 18.2 feet from a May 1947 high level of 37.1 below land surface to a new record low of 55.3 feet below land surface in May 1965. Water levels in well Manatee 92 have been declining at an average rate of 0.65 foot each year since 1941. Levels in well Sarasota 9 have declined 13.58 feet from 0.95 foot above land surface in May 1947 to a new record low level of 12.63 feet below land surface in May 1965. Levels in well Sarasota 9 have been declining at an average rate of about 0.5 foot per year since 1931. A comparison of hydrographs of levels in Manatee 92 to those of well Sarasota 9 shows the decline is continuing and that the range of fluctuations is increasing in both wells. The regional extent of the decline is shown by hydrographs of well Hillsborough 30 (figure 23) and of wells Manatee 92 and Sarasota 9 (figure 33). SOUTHERN FLORIDA The southern Florida section includes all counties south of a line through DeSoto County and 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 35. 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.

INFORMATION CIRCULAR NO. 61 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 has increased from an average of 40 mgy during 1941-45 to about 260 mgy in 1966 as shown in figure 38. 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 37. The hydrograph of well Martin 147 shows a slight 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, 1963 and 1965. The declines were caused, in part, by increased pumping in the Stuart well field. Although pumpage increased during 1965-66, water levels declined then rose in response to above average rainfall during 1965-66. Figure 39 shows trends of water levels and rainfall recorded at Stuart, 1965-66. The Biscayne aquifer is the chief source of water supply in southern Palm Beach, Broward, and Dade counties. Figure 40 shows the trends and fluctuations of end-of-month water levels in well Palm Beach 88 and rainfall data at West Palm Beach. Fluctuations of water levels for several selected wells are shown in figures 41 and 42. 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 Broward 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 (figure 42). The Biscayne aquifer contains salty water in areas adjacent to the coast and along tidal canals. Figure 43 shows graphs of the chloride content of water in well Broward S830 in the vicinity of the Ft. Lauderdale Dixie well field and in wells Dade F64 and F296 in North Miami Beach and Miami. The chloride content of water in well Broward S830 decreased from about 3,700 mg/1 in 1947 to about 50 mg/1 in 1958. From 1958 through 1963, chloride content increased to nearly 2,000 mgfl. In 1964 the chloride content decreased to about 1,700 mg/l and remained at 1,700 mg/1 during 1965-66. 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 aquifei, the extent of which is shown on figure 1. 1950 V, 1955 Figure 38.

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 throughout most of Dade County during 1965-66. Chloride content of ground water in the Biscayne aquifer in well Dade F296 on the coast north of Miami declined sharply from 500 to 100 mg/l during 1965-66. In northern Dade County, chlorides decreased from 900 mg/l in 1946 to less than 50 mg/l in 1963 in well Dade G354 and remained less than 50 mg/1 during 1963-66. In southern coastal Dade County, chloride content of ground-water in the Biscayne aquifer generally remained at low concentrations in most areas during 1965-66 although increases were noted in some areas. Chloride content increased from 250 mg/1 to more than 1,000 mg/1 in well Dade S529.

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 salty water contamination has been solved. In many areas where contamination existed the situation has been alleviated by water control. The effectiveness of the method of control is graphically illustrated in figure 47 by the chlorographs of wells Dade G212, G354, and S529.
