GEOLOGIC INTERPRETATION OF THE. AQUIFER
POLLTION POTENTIAL IN ALACHUA COUNTY, FLORIDA INTRODUCTION
This pr.oject wasi initiated at the request of the Alachua County
Department Of Environmental Services for the purpose of providing a hasic overview of the sediments overlying the Floridan aquifer system in Alachua County. Using well sample lithology data from 21 wells on file at the Florida Geological Survey as well as topographic mag analysis of land surface physiography, geologic cross sections were constructed and three major zones of relative aquifer confinement were delineated. Such information is essential to future land use planning and pollution control.


GEOLOGY
The following is a general overview of the Cenozoic geology of Alachua County. Information presented is condensed from work by Purl and Vernon (1964), Clark et al., (1964), Willtams et al., (1977), and Scott (1988, in press). Figure 1 shows the generalized Cenozoic stratigraphic section in

Alaehua County.
Ala-chua County is underlain by thick sequences of Paleocene and Eocene age marine limestones and dolomites ahd by Miocene to Holocene age mostly marine siliciclastic sediments. The Upper Paleocene to Lower Eocene Cedar Keys Formation and the Lower to Middle Eocene Oldsmar Limestone are deep carbonate units known only from oil test wells. They are generally not used as-a source of consumptive water,
The oldest formation penetrated by water wells within the county is the Middle Eocene Avon Park Formation. In the Alachua County area, the lithology of the Avon Park is typically a hard, dense, tan to dark brown dolostone or dolomitic limestone, occasionally containing beds of cream

colored limestone. This unit underlies all of Alachua County. It is thinnest and shallowest in the southwestern part of the county, where It occurs within 150 feet of the surface. Thickness of the Avon Park Formation may exceed 500 feet under eastern Alachua County.

Upper Eocene marine limestones of the Ocala Group unconformibly overlie the Avon Park Formation. The typical Ocala Group lithology grades from alternating tan to brown limestones and dolostones in the basal portion (Inglis and parts of the Williston Formations) to soft, white to tan fossiliferous limestone in the upper portion (upper part of Williston and the Crystal River Formations). The thickness of the Ocala Group sediments in Alachua County is approximately 200 feet. Both the Avon Park Formation and the Ocala Group are major components of the Floridan aquifer system.

Silicified boulders of the Oligocene age Suwannee Limestone occur in a few areas of northwestern and western Alachua County. This marine limestone may have been deposited unconformibly on Ocala Group sediments in most of what is now western Alachua County. Post-Oligocene erosion has removed all but a few isolated remnants of the Suwannee Limestone in this area. Well W-324, situated about three miles northwest of Gainesville, penetrated 21 feet of Suwannee sediments. The lithology of these sediments consisted of white chalky limestone containing macrofossil molds. This is the only well in Alachua County known to have penetrated Oligocene age section, and probably represents a local erosional remnant. Lithologically, the Suwannee Limestone is similar to the Ocala Group and is generally differentiated on fossils.

Clastic sediments of the Miocene age Hawthorn Group unconformibly overlie the Ocala Group sediments in central and eastern Alachua County. The Hawthorn Group sediments are predominantly green, blue, or gray clays








and sandy clays, sometimes containing Interbeddded phosphatic limestone and dolostone. In eastern Alachua County, Hawthorn sediments are generally sandier and more phosphatic, with dolostone common in the basal portions. Thickness of the Hawthorn sediments ranges from zero where it pinches out on Ocala Group limestone in west-central Alachua County, to almost 150 feet in the north-east corner of the county. Anomalously thick occurences of Hawthorn throughtout the perforated area are most likely sinkhole fill deposits. The clays, clayey sands and carbonates in the Hawthorn Group serve to confine the Floridan aquifer system.
In a small area in southwestern Alachua County, adjacent to the

Brooksville Ridge, localized sinkhole and channel fill deposits of what has previously been called the Alachua Formation lie directly on the Ocala Group limestone. These white, gray, or buff sands frequently contain clays, phosphate pebbles, and vertebrate fossils, and most likely represent weathered and reworked Hawthorn Group deposits (Scott, 1988 in press).

The Plio-Pleistocene age Cypresshead Formation forms the core of the Brooksville Ridge, situated in extreme southwestern Alachua County. These

variahly-colored, red to pink to orange clayey and gravelly sands are lithologically similar to the Citronelle Formation of the Florida Panhandle. Where present, they overlie the Ocala Group, and are in turn overlain hy undifferentiated Pleistocene sands.

Undifferentiated sands and clayey sands of Pleistocene to Holocene age form a thin veneer over most of Alachua County. In the western portion of the county, these relatively porous sands lie directly on Ocala Group limestones or Cypresshead Formation. In central and eastern Alachua County,

these sands overlie the Hawthorn Group sediments. Karst features (sinkholes and caves) developed in the Ocala Group limestone may contain substantial thicknesses of fill composed of these sands.








AQUIFER CONFINEMENT ZONE MAP
The aquifer confinement zone map illustrates three primary zones of relative aquifer confinement. These zones were derived and delineated based on the sediment types and thicknesses overlying the Floridan aquifer system as well as the geomorphology.
These three zones, in terms of potential connection to the Floridan aquifer system, are as follows:. 1) the confined zone, 2) the perforated zone, and 3) the unconfined zone.

Confined Zone
A zone of relative aquifer confinement stretches from north-central Alachua County southeastward comprising most of the eastern half of the county. This zone is characterized by generally higher elevations underlain by phosphatic clayey sands, sandy clays, and carbonates of the Hawthorn Group. For the purposes of this study, areas underlain by at least ten feet of Hawthorn Group sediments were included in the confined zone. In general, the Hawthorn ranges in thickness from 0 feet in western Alachua County to approximately i50 feet in the northeastern part of the county. Topographic quadrangle maps covering Alachua County were analyzed to ascertain the areal extent of the physiographically high areas whAich do not show signs of karst development. The boundary between the confined and perforated zones delimits the areas of continuously confining clays from

those with significant perforations by karst features.


Perforated Zone
The perforated zone trends southeastward in a variable, one-to-five
mile wide band roughly parelleling Interstate 75. Sediments underlying the perforbted zone may contain substantial thickness of clays, but are per-

forated by numerous karst features. These features allow.direct hydrologic access to the aquifer. The western houndary of the perforated zone reflects the areal limit of Hawthorn Group clays.

Small, isolated areas of perforated zone occur in the north-central

portion of the county near Cooter Pond, and in southeastern Alachua County in the vicinity of Hawthorne. Roth area's occur within the confined zone hut are mapped as perforated because they contain significant karst development or lakes with hydrologic connection to the Floridan aquifer system.


Unconfined Zone
The Floridan aquifer system in western and southwestern Alachua County is overlain by highly permeable and generally thin, undifferentiated sands. These porous sands comprise an area of high aquifer recharge and allow pollutants direct access to the aquifer. Within this zone, the terrain is low and flat. Well sample logs indicate that little or no clay is present in the sediments.


GEOLOGIC CROSS-SECTIONS

Three geologic cross-sections through Alachua County were constructed using lithologic and formational data from wells on file at the Florida Geological Survey. Horizontal scale is the same as that of the Aquifer Zone Map, and cross section location lines are provided as an overlay to that map. Vertical scale is exaggerated 250 times to show the necessary strata. Surface relief was obtained from USGS topographic quadrangle maps. The yellow strata represents the Plio-Pleistocene undifferentiated sands and clayey sands. Green represents the mostly Miocene age Hawthorn Group sediments and blue represents Eocene limestones of the Floridan aquifer system. In most water wells, the Ocala Group limetones are the deepest







water-hearing units tapped. A few wells however penetrate limestone of the
deeper Avon Park Formation.
Figure 2 shows the three cross-section locations in Alachua County. Cross-section A-A' runs west to east through Gainesville to just east of Hawthorne. Section R-RI trends west to east across northern Alachua County from High Springs to just east of Waldo. Cross-section C-C' runs north to south from LaCrosse to south of Micanopy. Wells used in the cross sections

are numbered according to the Florida Geological Survey accession numbers;. these numbers consist of a "W-" followed by a one-to-five-digit number unique to each well.

Well Location

Wells are located according to the Township-Range System. The basic units of this system area townships, which are numbered consecutively both north and south of the Tallahassee Base Line. Ranges are numbered consecutively both east and west of the Principal Meridan. Each township is divided into 36 equal one-square-mile pieces called sections. Sections are in turn divided into quarter-quarter sections. The two letters following each section number listed in Table 1 reflect the quarter-quarter section location of the well. The letter A designates the NW quarter, 9 the NE quarter, C the SW quarter, and 0 the SE quarter. Quarter-quarter sections are designated the same way. For example, the location of a well in section 32AD would be in the northwest quarter of the southeast quarter of section 32. Table I lists the wells used to construct each cross-section, and Appendix I is a series of lithologic summaries for these wells.
