GEOHYDROLOGY AND 1985 WATER WITHDRAWALS OF THE AQUIFER SYSTEMS IN

SOUTHWEST FLORIDA, WITH EMPHASIS ON THE INTERMEDIATE AQUIFER SYSTEM

By A.D. Duerr, J.D. Hunn, B.R. Lewelling, and J.T. Trommer

ABSTRACT

In a 4,700-square-mile area of southwest Florida, principal hydrogeologic units are the surficial aquifer system, the intermediate aquifer system, and the Floridan aquifer system. The thickness of the surficial aquifer system ranges from 25 to 250 feet, and transmissivity ranges from about 1,100 to about 8,000 feet squared per day.

The intermediate aquifer system includes all water-bearing units and confining units between the overlying surficial aquifer system and the under­ lying Floridan aquifer system. The top of the intermediate aquifer system ranges from more than 100 feet below sea level in Highlands County to more than 100 feet above sea level in central Polk County. Thickness ranges from less than 100 feet to more than 800 feet, and transmissivity ranges from less than 200 to about 13,000 feet squared per day. Leakance of the confining units ranges from 1x10 7 to 4x10 4 foot per day per foot.

The Floridan aquifer system consists of the Upper and Lower Floridan aquifers separated by a "tight" middle confining unit. Transmissivity of the Upper Floridan aquifer in the study area ranges from about 30,000 feet squared per day at the gulf coast where the freshwater zone is thin to about 400,000 feet squared per day in eastern De Soto and Hardee Counties.

The altitude of the potentiometric surface of the intermediate aquifer system in September 1985 ranged from 120 feet above sea level in Polk County to less than 20 feet above sea level near the coast. In the northern part of the study area, water levels are higher in the intermediate aquifer system than water levels in the underlying Upper Floridan aquifer. The hydraulic gradient reverses in the southern part of the area.

In 1985, in the study area, an estimated 808 million gallons per day of freshwater was withdrawn from the surficial and intermediate aquifer systems and Upper Floridan aquifer for irrigation, public and rural supply, and indus­ trial use. Of this total, an estimated 68.9 million gallons per day was withdrawn from the intermediate aquifer system.

INTRODUCTION

Southwest Florida has developed rapidly during the 1980's and in 1985 was one of the leading population growth areas in the State. Associated with this growth is an increasing demand for water for public supply, industrial, and agricultural uses.

In southwest Florida, ground water is the principal source of freshwater because of the lack of adequate surface-water storage. Three hydrogeologic units serve as a source of freshwater: the surficial aquifer system, the intermediate aquifer system, and the Floridan aquifer system. Because of low yield to wells and the potential for pollution, the surficial aquifer system has limited use, generally for lawn and garden irrigating and stock watering. The Upper Floridan aquifer of the Floridan aquifer system is the principal source of supply and yields large quantities of freshwater to wells in most areas. However, in the southern and coastal parts of the study area, the Upper Floridan aquifer contains water with a high mineral content. The inter­ mediate aquifer system is an important source of water in Charlotte and Sarasota Counties; it also is used as a source of water throughout much of De Soto, Hardee, Highlands, Hillsborough, Manatee, and Polk Counties, although yields of individual wells and total withdrawal of water from the aquifer are generally much less than from wells open to the deeper Upper Floridan aquifer.

As the demand for water in southwest Florida increases, more information about the intermediate aquifer system is needed in order to more efficiently develop and manage this aquifer system as a water-supply source. Thus, in 1983, the U.S. Geological Survey, in cooperation with the Southwest Florida Water Management District, began a project to study the geohydrology of the intermediate aquifer system in southwest Florida.

Purpose and Scope

The purpose of this report is to present geohydrologic and water-use information on the intermediate aquifer system that will aid in the management of the aquifer system. Information on the surficial and Floridan aquifer systems is also presented but in less detail. The study area includes the southern half of the Southwest Florida Water Management District, an area of about 4,700 mi2 , and includes all of De Soto, Hardee, Manatee, and Sarasota Counties and parts of Charlotte, Highlands, Hillsborough, and Polk Counties (fig. 1).

This report presents a description of the surficial, intermediate, and Floridan aquifer systems, defines the geohydrologic framework, and presents water-withdrawal data, potentiometric-surface maps, a table showing records of wells, and an index of geophysical logs. The depth, thickness, and extent of the intermediate aquifer system was determined from geologic and geophysical logs of wells from the files of the U.S. Geological Survey, the Florida Bureau of Geology, and the Southwest Florida Water Management District. A network of water-level observation wells was established and measured to determine the potentiometric surface of the intermediate aquifer system for September 1985 and May 1986.

Previous Investigations

Numerous reports have been written about the geology and hydrology of southwest Florida, but few reports focus specifically on the intermediate aquifer system. Most of the published information about the aquifer system is limited to public well fields and phosphate plant sites where test drilling has been completed and aquifer tests conducted.

Several previous reports provide geologic and ground-water information. Stringfield (1933a; 1933b) described the geology and ground-water conditions in Sarasota County. Heath and Smith (1954) described the ground-water re­ sources in Pinellas County. The stratigraphy of shallow deposits in De Soto and Hardee Counties was reported by Bergendahl (1956) . Bishop (1956) iden­ tified marine and nonmarine deposits of the Hawthorn Formation in Highlands County. Peek (1958; 1959a; 1959b) described the geology and ground-water resources in Manatee and southwest Hillsborough Counties. The water resources of Hillsborough County also were described by Menke and others (1961). Eppert (1966) reported on the stratigraphy of the upper Miocene deposits in Sarasota County, and Stewart (1966) described the ground-water resources of Polk County. Kaufman and Dion (1968) presented data on the ground-water resources of Charlotte, De Soto, and Hardee Counties. The water resources of Charlotte County were further described by Sutcliffe (1975) . Joyner and Sutcliffe(1976) reported on the water resources of the Myakka River basin area. Wilson(1977) provided information on the ground-water resources of De Soto and Hardee Counties that included the geology and hydrology of the intermediate aquifer. Hutchinson (1978) gave an appraisal of the shallow ground-water resources in the upper Peace and eastern Alafia River basins.

Buono and others (1979) presented the generalized thickness of the con­ fining unit overlying the Upper Floridan aquifer throughout southwest Florida. Franks (1982) presented summary information on the principal aquifers in Florida. Brown (1983) described the upper confining unit and presented water- level data for the intermediate aquifer system in Manatee County. Wolansky (1983) subdivided the intermediate aquifer into several units in the Sarasota- Port Charlotte area. A description of the intermediate aquifer was included by Miller (1986) in his regional description of the Floridan aquifer system. Corral and Wolansky (1984) mapped the configuration of the top of the inter­ mediate aquifer system in southwest Florida but did not include the confining layer below the surficial aquifer system as part of the intermediate aquifer system. The geology of the intermediate aquifer system was included in a report by Ryder (1985) describing the hydrology of the Floridan aquifer system in west-central Florida. A report by Duerr and Wolansky (1986) described the hydrogeology of the surficial and intermediate aquifer systems of central Sarasota County, Florida.

Description of the Area

The area is highly urbanized near the coast and rural in the interior. Major industries include agriculture, phosphate mining, chemical processing, food processing, and tourism. Agricultural land use includes citrus groves, vegetable farms, nurseries, and rangeland.

Topography is characterized by a low-lying coastal plain that gradually rises toward the east and is bordered by sand-covered ridges more than 150 feet above sea level (fig. 2). There are numerous lakes in the ridge areas. Surface-water drainage is relatively well developed with streams draining south and west into the Gulf of Mexico.

The climate of southwest Florida is characterized by warm, humid summers and mild, moderately dry winters. The Gulf of Mexico moderates the extremes in temperature so that winter low temperatures are several degrees higher along the coast than in inland areas. The average July temperature at Wauchula (fig. 3) is 81.5 °F and the average January temperature is 61.5 °F. Rainfall varies seasonally with more than half the annual total occurring from June to September. Average rainfall from five weather stations (A through E, fig. 3) for the period 1915 to 1976 was 53.1 in/yr (Palmer and Bone, 1977, p. 6).

GEOHYDROLOGIC FRAMEWORK AND HYDRAULIC PROPERTIES

The geohydrologic system in the study area consists of thick sequences of carbonate rock overlain by clastic deposits. Principal hydrogeologic units are the surficial aquifer system, the intermediate aquifer system, and the Floridan aquifer system (Southeastern Geological Society, 1986). The hydro- geologic units, the corresponding time-stratigraphic units, and general lithology are given in table 1.

The surficial aquifer system overlies the intermediate aquifer system and consists of Holocene and Pleistocene deposits containing sand, clayey sand, shell, shelly marl, and some phosphorite. The thickness of the deposits was mapped by Wolansky, Spechler, and Buono (1979). Thickness ranges from about 25 feet near the coast and low-lying areas to about 250 feet in Highlands County. The surficial aquifer system is a major source of recharge to the intermediate aquifer system. The surficial aquifer system is unconfined and is not a major source of water except in the southern part of the study area where deeper limestone aquifers are highly mineralized.

The hydraulic properties of the surficial aquifer system vary with saturated thickness and lithology. Wolansky (1983, p. 16) reported hydraulic properties from six aquifer tests in Sarasota and southwestern De Soto Counties; transmissivity ranges from 600 to 8,000 ft 2 /d, and storage coeffi­ cient determined from two tests ranges from 0.05 to 0.16. R.M. Wolansky (U.S. Geological Survey, written commun., 1980) reported a transmissivity of 1,800 ft 2 /d for a site in southeast Hillsborough County. For two sites in southern Polk County, Hutchinson (1978, p. 20) reported transmissivities of 1,600 and 2,200 ft 2 /d and storage coefficients of 0.05 and 0.005. Wilson (1977, p. 28) estimated an average transmissivity of about 1,100 ft 2 /d for the surficial aquifer system in Hardee and De Soto Counties.

The intermediate aquifer system includes all water-bearing units (aquifers) and confining units between the overlying surficial aquifer system and the underlying Floridan aquifer system. The water-bearing units of the intermediate aquifer system consist of discontinuous sand, gravel, shell, and limestone and dolomite beds in the Tamiami Formation of early Pliocene age and the Hawthorn Formation of late and middle Miocene age.

aquifer system contains confining units that consist of sandy clay, clay, and marl. These confining units retard vertical movement of ground water between the water-bearing units and the overlying surficial aquifer system and the underlying Upper Floridan aquifer.

In parts of Polk, Manatee, Hardee, De Soto, Sarasota, and Charlotte Counties, sand and clay beds within the Tampa Limestone are hydraulically con­ nected to the Hawthorn Formation and are also included in the intermediate aquifer system (Corral and Wolansky, 1984). In these areas, a confining unit separates the Tampa Limestone from the underlying Floridan aquifer system.

Within the intermediate aquifer system are deposits of sufficient perme­ ability to be used as important water supplies in coastal areas. In coastal Charlotte and Sarasota Counties, the intermediate aquifer system contains some slightly saline water that is treated by reverse osmosis before it is used for public supply (Sutcliffe and Thompson, 1983). In other parts of the study area, water from the intermediate aquifer system receives only minimal treat­ ment before being distributed for use.

The intermediate aquifer system thus consists of three hydrogeologic units (table 1): (1) a sandy clay and clayey sand confining unit in the lower part that lies directly on top of the Floridan aquifer system; (2) an aquifer system that consists of one, two, or three water-bearing units (aquifers) composed primarily of sand and carbonate rocks; and (3) a sandy clay, clay, and marl confining unit in the upper part that separates the aquifers in the intermediate aquifer system from the overlying surficial aquifer system (Ryder, 1985).

The water-bearing units (aquifers) of the intermediate aquifer system are equivalent to the secondary artesian aquifer as used by Stewart (1966) for Polk County; to zones 2 and 3 as used by Sutcliffe (1975) for Charlotte County; to the upper and lower Hawthorn aquifers as used by Sproul and others (1972) for part of Lee County; and to the upper unit of the Floridan aquifer as used by Wilson (1977) for De Soto and Hardee Counties,

The locations of six generalized geohydrologic sections are shown in figure 4. The sections, shown in figures 5 through 10, were constructed pri­ marily from geologists' logs of test wells. Geophysical logs also were used for correlating aquifers. The sections show the relative positions of the surficial, intermediate, and Floridan aquifer systems. The sections also show the confining units and water-bearing units (aquifers) at specific test holes within the intermediate aquifer system. There are lateral inconsistencies between interpretations of rock stratigraphic units in the study area and they are not included in the sections.

In southwest Florida, the top of the intermediate aquifer system ranges from more than 100 feet below sea level in Highlands County to more than 100 feet above sea level in central Polk County (fig. 11). Throughout most of the southern and western parts of the study area, the top of the intermediate aquifer system is within 50 feet of sea level. Along the gulf coast, it lies about 20 feet below sea level. The thickness of the intermediate aquifer system ranges from less than 100 feet in central Hillsborough and northern Polk Counties to more than 800 feet in southern Charlotte County (figs. 6, 7, and 12). The intermediate aquifer system is intermittent near its northern extent and its boundary is approximated by a dashed line in figure 12. The bottom of the intermediate aquifer system (top of the Floridan aquifer system)

ranges from about 50 feet above sea level in northern Polk county to more than 800 feet below sea level in southern Charlotte County (fig. 13).

Transmissivities of the water-bearing units of the intermediate aquifer system, as determined by field tests, are shown in figure 14 (Ryder, 1982). Transmissivity ranges from less than 200 to about 13,000 ft2/d. Transmissiv- ity is generally less than 1,000 ft2/d in eastern Hillsborough and northern Polk Counties where the permeable deposits are thin. Near the Peace River, transmissivity is generally higher than 4,000 ft2 /d, indicating that perhaps a more active flow system exists in a carbonate section where ground water discharges to the river and the carbonate rocks' secondary porosity has been enhanced by dissolution, thus providing greater permeability (Ryder, 1982, p. 23).

Clay beds of limited lateral extent and variable thickness may occur within the water-bearing units of the intermediate aquifer system, particular­ ly near the coast. Where laterally persistent clay beds occur, the water­ bearing units have been separated into two or three local artesian zones by some investigators (Joyner and Sutcliffe, 1976; Sutcliffe and Thompson, 1983; Wolansky, 1983).

The water-bearing units of the intermediate aquifer system are confined above and below by less permeable material. Leakance of the uppermost confining unit used by Ryder (1985) in a ground-water flow model of west- central Florida ranges from 7x10" 6 (ft/d)/ft in western Manatee County to 4x10 4 (ft/d)/ft near the Tampa Bay coast in southwest Hillsborough County. Leakance of the lowermost confining unit of the intermediate aquifer system ranges from 1x10 7 (ft/d)/ft in southwest Sarasota and western Charlotte Counties to 7x10" 5 (ft/d)/ft in the eastern part of the study area (Ryder, 1985) . The confining units have low hydraulic conductivity and consequently retard interaquifer ground-water flow and yield little water to wells. However, these confining units do transmit, or leak, water from one aquifer to another, and the system is referred to as a leaky-aquifer system (Wilson, 1977, p. 37).

The underlying Floridan aquifer system is defined as a vertically con­ tinuous sequence of carbonate rocks of generally high permeability that are of Tertiary age, that are hydraulically connected to each other in varying degrees, and whose permeability is several orders of magnitude greater than that of the rocks that bound the system above and below (Ryder, 1985).

The Floridan aquifer system (Miller, 1986) consists of the Upper and Lower Floridan aquifers separated by a "tight" middle confining unit. The middle unit and Lower Floridan aquifer generally contain saltwater (Ryder, 1985). In most reports on the hydrology of southwest Florida, the term "Floridan aquifer" has been applied to the water-bearing rocks herein referred to as the Upper Floridan aquifer. It is the major source of fresh ground water for most of southwest Florida. Transmissivity of the Upper Floridan aquifer in the study area ranges from about 30,000 ft2 /d at the gulf coast where the freshwater zone is thin to about 400,000 ft2 /d in eastern De Soto and Hardee Counties (Ryder, 1985).

POTENTIOMETRIC SURFACE

The potentiometric surface, or hydraulic head, is an imaginary surface connecting points to which water would rise in tightly cased wells from a given point in an aquifer (Lohman, 1972). Potentiometrie-surface maps of the intermediate aquifer system were constructed from water-level measurements made in 115 wells (fig. 15). Construction data and measurements for September 1985 and May 1986 are shown in appendix A. Wells were measured at the end of the normally wet season (September) and at the end of the normally dry season (May). In areas where multiple aquifers exist in the intermediate aquifer system, wells open to all aquifers in the system were selected for water-level measurements whenever possible. Thus, the potentiometric-surface maps of the intermediate aquifer system represent an average pressure surface.

The potentiometric surface of the intermediate aquifer system in September 1985 is shown in figure 16. The altitude of the potentiometric sur­ face ranges from about 120 feet above sea level in Polk County to less than 20 feet above sea level near the coast. Lateral flow from areas of high poten­ tial to areas of low potential is generally south and west toward the coast.

The potentiometric surface of the underlying Upper Floridan aquifer in September 1985 was mapped by Barr (1985) and is shown in figure 17. Head differences between the intermediate aquifer system and the Upper Floridan aquifer in September 1985 are shown in figure 18. In the northern part of the study area, heads in the intermediate aquifer system are higher than heads in the underlying Upper Floridan aquifer. Water is transmitted downward through the confining unit and recharges the Upper Floridan aquifer. The gradient in head reverses in the southern part of the study area where the underlying Upper Floridan aquifer has a higher head than the head in the intermediate aquifer system. There, water is transmitted upward through the confining unit and recharges the intermediate aquifer system. Head differences between the intermediate aquifer system and the Upper Floridan aquifer range from more than +60 feet near the corner of Hillsborough, Manatee, Polk, and Hardee Counties to about -15 feet in western Sarasota County.

The potentiometric surface of the intermediate aquifer system is general­ ly higher than the water level in the surficial aquifer system in the low- lying areas near the Peace River. As a result, in these areas, ground water moves upward from the intermediate aquifer system into the surficial aquifer system. The upward flow tends to depress the potentiometric surface of the intermediate aquifer system near the Peace River (fig. 16). Along reaches of the river where the Hawthorn Formation crops out, as in parts of Hardee and northern De Soto Counties, ground water may discharge by spring flow directly from the intermediate aquifer system to the river.

Figure 19 shows the potentiometric surface of the intermediate aquifer system in May 1986 near the end of the dry season when ground-water withdraw­ als are greatest and water levels are at their seasonal low. The altitude of the potentiometric surface ranges from about 120 feet above sea level in Polk County to less than 10 feet above sea level near the coast. The decline in the potentiometric surface from September 1985 to May 1986 ranged from about 1 to 20 feet and resulted from ground-water withdrawals. Largest declines were in south-central Polk, central Hardee, and north-central De Soto Counties. Smallest declines were in Charlotte County.

The potentiometrie surface of the Upper Floridan aquifer in May 1986 is shown in figure 20. Head differences between the two aquifers are shown in figure 21. As in September 1985, the potentiometric surface of the inter­ mediate aquifer system in May 1986 was greater than the potentiometric surface of the underlying Upper Floridan aquifer throughout the northern part of the study area. Head differences were greater in May 1986 than in September 1985 and the area where the intermediate aquifer system heads were higher extended further south. Head differences ranged from more than +100 feet in southwest­ ern Polk County to about -10 feet in Charlotte County.

Large head differences between the Upper Floridan aquifer and the inter­ mediate aquifer system in May 1986 in the northern half of the study area were caused by large ground-water withdrawals from the Upper Floridan aquifer for irrigation during the dry spring season. The potentiometric surface of the intermediate aquifer system was only slightly lower in May than in September because of relatively small ground-water withdrawals from the intermediate aquifer system for irrigation during the dry spring season.

The Southwest Florida Water Management District has drilled a network of monitoring wells at ROMP sites (Regional Observation and Monitor-well Program) . Locations of ROMP sites are shown in figure 22. Hydrographs of paired ROMP wells are shown in figures 23 through 31 and illustrate the head difference between the aquifer system throughout the study area. Monthly rainfall is also shown in these figures. The hydrographs show water-level responses to seasonal rainfall variations and ground-water withdrawals. Gen­ erally, water levels are highest at the end of the wet season (June through September) and lowest at the end of the dry season (April and May). The dry spring season is also the period of peak water use, and large ground-water withdrawals also contribute to the seasonal decline in water levels.

ROMP sites 57, 59, 40, and 45 in Polk County (figs. 23 through 26) and ROMP site 31 in Hardee County (fig. 27) show that the intermediate aquifer system has a potentiometric surface greater than that of the underlying Upper Floridan aquifer in the northern part of the study area. ROMP sites TR5-1 and TR5-2 in Sarasota County and TR3-1 in Charlotte County show that these gradi­ ents are reversed in the south as heads increase with depth (figs. 29 through 31).

Hydrographs at ROMP sites 45, 31, and 26 in southern Polk, central Hardee, and northern De Soto Counties show that small (1 to 4 feet) head dif­ ferences and similar fluctuation patterns exist for wells in the intermediate aquifer system and wells in the Upper Floridan aquifer (figs. 25, 27, and 28). This suggests that leaky, fairly permeable confining beds allow relatively good connection between aquifers in the central part of the study area.

Hydrographs at ROMP sites 57 and 59 in central Polk County show a large head difference between aquifers (figs. 23 and 24). Water levels are 10 to 15 feet higher in the intermediate aquifer system than in the underlying Upper Floridan aquifer. This suggests that the confining beds between aquifers are relatively impermeable.

Hydrographs at ROMP site 40 in southwestern Polk County also show large head differences between aquifers (fig. 26). Water levels are 70 to 110 feet higher in the intermediate aquifer system than in the underlying Upper Floridan aquifer.

The confining beds are also relatively impermeable in the southern part of the study area where water levels are significantly lower in the intermedi­ ate aquifer system than in the Upper Floridan aquifer as shown in the hydro- graphs at ROMP sites TR5-1, TR5-2, and TR3-1 in Sarasota and Charlotte Counties (figs. 29 through 31). Hydrographs at ROMP sites TR5-2 and TR3-1 show water levels increasing with depth in three different zones within the intermediate aquifer system at each site.

GROUND-WATER WITHDRAWAL

Ground-water withdrawal data for the Southwest Florida Water Management District are collected cooperatively by the Southwest Florida Water Management District and the U.S. Geological Survey. A combined total of about 1,288 Mgal/d of fresh ground water was withdrawn from the surficial, intermediate, and Upper Floridan aquifers in 1985 for irrigation, public and rural supply, and industrial use (Stieglitz, 1986). Of this total, an estimated 808 Mgal/d was withdrawn in the study area. Withdrawal data are not delineated by individual aquifers.

The Upper Floridan aquifer is by far the most productive aquifer and supplies more than 10 times the amount of water pumped from either the surfi­ cial aquifer system or the intermediate aquifer system in most of the study area. However, the importance of the Upper Floridan aquifer as a source of water diminishes as the water quality in the aquifer decreases in the southern and western parts of the study area where concentrations of dissolved solids, chloride and sulfate exceed 1,000, 250, and 250 mg/L, respectively (Wolansky, 1983; p. 32). The saline water is the probable result of past marine inunda­ tions and subsequent mixing and water-rock reactions (Steinkampf, 1982, p. 1). In these areas , the intermediate aquifer system is the most important source of ground water for public supply because it has better water quality.

Following is an estimate of the amount of freshwater withdrawn from the intermediate aquifer system in 1985 in the study area and an explanation of the techniques used to make the estimate. Withdrawals outside of the Southwest Florida Water Management District boundary are not included in the estimate.

Estimates of water withdrawn from the intermediate aquifer system were based upon: (1) Southwest Florida Water Management District well construction and consumptive-use permitting files; (2) U.S. Geological Survey Ground-Water Site Inventory Files; (3) specific capacity and transmissivity data for vari­ ous aquifers; and (4) data reported by previous investigators, such as Sutcliffe (1975), Wilson (1977), and Stieglitz (1986).

Well construction was the primary factor for estimating water withdrawn from the intermediate aquifer system. Depth and casing of withdrawal wells in each county were estimated from well-construction data. The depth and casing data indicated from which aquifer or aquifers the well was producing water. In areas where wells were constructed with producing zones in more than one aquifer, the ratio of the specific capacities or transmissivities of the two aquifers from the site or a nearby site was used to estimate the proportion of water withdrawn from each aquifer. Information on sources of withdrawals reported by previous investigators also was used to estimate withdrawals from the system.

41

An estimated 68.9 Mgal/d of water was withdrawn for all use categories in 1985 from the intermediate aquifer system in the Southwest Florida Water Management District (table 2). The largest withdrawal of ground water was for irrigation, about 38.8 Mgal/d. Of this total, 15.0 Mgal/d was withdrawn in Charlotte County. The largest withdrawal of ground water from the system for all use categories was in Sarasota County, about 18.3 Mgal/d (Stieglitz, 1986).

Public Supply

The public supply category includes all water distributed by public- supply water systems to households, industry, agriculture, and other purposes (Duerr and Sohm, 1983). A total of about 97.8 Mgal/d of ground water was withdrawn for public supply from all aquifers in the study area in 1985 (Stieglitz, 1986). Of this total, about 11.1 Mgal/d was withdrawn from the intermediate aquifer system (table 2). The largest withdrawals from the intermediate aquifer system for public supply were in Sarasota County, about 10.0 Mgal/d.

Rural Supply

The rural supply category includes all water supplied to households that are not supplied by large (withdrawing more than 100,000 gal/d) public-supply systems. This includes households that have their own water supply and house­ holds that are supplied by small public-supply systems. Well diameters generally range from 2 to 4 inches.

42

Ground water withdrawn for rural use from all aquifers in the study area in 1985 averaged about 29.8 Mgal/d (Stieglitz, 1986). Of this total, about 14.2 Mgal/d was withdrawn from the intermediate aquifer system (table 2). The largest rural water withdrawals were from the intermediate aquifer system, about 4 Mgal/d, and occurred in Polk County.

Industrial Supply

The industrial supply category includes water used by industries that supply their own water. Data do not include water sold to industries by public-supply systems.

Ground water withdrawn for industrial purposes from all aquifers in the study area in 1985 averaged about 159.7 Mgal/d (Stieglitz, 1986). Of this total, about 4.8 Mgal/d was withdrawn from the intermediate aquifer system (table 2). Polk County had the largest withdrawal from the intermediate aquifer system in this category, about 4.2 Mgal/d, most of which was withdrawn for phosphate mining, chemical processing, and citrus processing.

Irrigation Supply

The irrigation supply category includes water withdrawn by irrigators from private wells and does not include water supplied by public-supply sys­ tems. Irrigation water use is generally not metered and estimates of water use for irrigation are the least accurate of all water-use data. For a more complete discussion of irrigation water use see Duerr and Sohm (1983) and Stieglitz (1986).

Ground water withdrawn for irrigation from all aquifers in the study area in 1985 averaged about 521 Mgal/d (Stieglitz, 1986). Of this total, about 38.8 Mgal/d was withdrawn from the intermediate aquifer system (table 2). Irrigation withdrawals were largest in Charlotte County, 15 Mgal/d, most of which was for citrus and vegetable irrigation.

SUMMARY

The study area includes the southern part of the Southwest Florida Water Management District, an area of about 4,700 mi 2 . The area is characterized by a low-lying coastal plain bordered by sand-covered ridges along the north and east that are more than 150 feet above sea level. The climate is warm with humid summers and mild, moderately dry winters. The average annual rainfall of five stations in southwest Florida for the period 1915 to 1976 was 53.1 inches.

Principal hydrogeologic units are the surficial aquifer system, the intermediate aquifer system, and the Floridan aquifer system. The surficial aquifer system overlies the intermediate aquifer system and consists of Holocene and Pleistocene age deposits containing sand, clayey sand, shell, shelly marl, and some phosphorite. Thickness ranges from about 25 feet near the coast and low-lying areas to about 250 feet in Highlands County. Trans- missivity ranges from about 1,100 to about 8,000 ft2 /d.

The intermediate aquifer system includes all water-bearing units and confining material between the overlying surficial aquifer system and the underlying Floridan aquifer system. The intermediate aquifer system consists of three hydrogeologic units: (1) a sandy clay and clayey sand confining unit in the lower part that lies directly on the Floridan aquifer system; (2) an aquifer system that consists of one, two, or three water-bearing units (aquifers) composed primarily of sand and carbonate rocks; and (3) a sandy clay, clay, and marl confining unit in the upper part that separates the water-bearing unit in the intermediate aquifer system from the overlying surficial aquifer system.

The top of the intermediate aquifer system ranges from more than 100 feet below sea level in Highlands County to more than 100 feet above sea level in Polk County. The thickness of the intermediate aquifer system ranges from less than 100 feet in central Hillsborough and northern Polk Counties to more than 800 feet in southern Charlotte County.

Total transmissivity of aquifers within the intermediate aquifer system ranges from less than 200 ft2/d where the permeable deposits are thin to about 13,000 ft2/d in the carbonate section near the Peace River. Leakance of the confining beds within the intermediate aquifer system ranges from 1x10 7 to 4xlO" 4 (ft/d)/ft.

The underlying Floridan aquifer system is defined as a vertically con­ tinuous sequence of carbonate rocks of generally high permeability that are of Tertiary age, that are hydraulically connected to each other in varying degrees, and whose permeability is several orders of magnitude greater than that of the rocks that bound the system above and below.

The Floridan aquifer system consists of the Upper and Lower Floridan aquifers separated by a "tight" middle confining unit. The middle unit and Lower Floridan aquifer generally contain saltwater. In most reports on the hydrology of southwest Florida, the term "Floridan aquifer" has been applied to the water-bearing rocks herein referred to as the Upper Floridan aquifer. It is the major source of fresh ground water for most of southwest Florida. Transmissivity of the Upper Floridan aquifer in the study area ranges from about 30,000 ft2/d at the gulf coast where the freshwater zone is thin to about 400,000 ft2/d in eastern De Soto and Hardee Counties.

A comparison of the potentiometric surface of the intermediate aquifer system and the underlying Upper Floridan aquifer shows that in the northern part of the study area, heads in the intermediate aquifer system are higher than heads in the underlying Upper Floridan aquifer. Water is transmitted downward through the confining unit and recharges the Upper Floridan aquifer. The gradient in head reverses in the southern part of the study area where the underlying Upper Floridan aquifer has a higher head than the head in the intermediate aquifer system. There, water is transmitted upward through the confining unit and recharges the intermediate aquifer system.

The potentiometric surface of the intermediate aquifer system is general­ ly higher than the water level in the surficial aquifer system in the low- lying areas near the Peace River. As a result, in these areas, ground water moves upward from the intermediate aquifer system into the surficial aquifer system.

44

The Upper Floridan aquifer is by far the most productive aquifer and supplies more than 10 times the amount of water pumped from either the surfi- cial aquifer system or the intermediate aquifer system in most of the study area. However, the importance of the Upper Floridan aquifer as a source of water diminishes as the water quality in the aquifer decreases in the southern and western parts of the study area where concentrations of dissolved solids, chloride and sulfate exceed 1,000, 250, and 250 mg/L, respectively. In these areas the importance of the intermediate aquifer system as a source of water increases.

In 1985, an estimated 808 Mgal/d of freshwater was withdrawn in the study area from the surficial and intermediate aquifer systems and Upper Floridan aquifer for irrigation, public and rural supply, and industrial use. Of this total, an estimated 68.9 Mgal/d was withdrawn from the intermediate aquifer system. Sarasota County used the most water from the system for all use categories, about 18.3 Mgal/d.
