saltwater intrusion of the aquifer from underlying brine-filled strata at Brunswick, Ga., and near Jacksonville, Fla.
The Coastal Sound Science Initiative is a series of scientific and feasibility studies to support development of the State of Georgia's final strategy to protect the Upper Floridan aquifer from saltwater contamination (Georgia Environtnental Protection Division, 1997). As part ofthe Coastal Sound Science Initiative, the U.S. Geological Survey (USGS)-in cooperation with the Georgia Environmental Protection Division (GaEPD}--is developing numerical models to simulate ground-water flow and solute transport (saltwater contamination). To support this effort, detailed information regarding the hydraulic properties of the Floridan aquifer system were compiled; these data include transmissivity, storage coefficient, and vertical hydraulic conductivity.
Purpose and Scope
This report presents a compilation of existing hydraulicproperty data for the Floridan aquifer system and equivalent aquifer units of coastal Georgia, southeastern South Carolina, and northeastern Florida. Data include analysis of transmissivity at 324 well.s, storage coefficient at 115 wells, and vertical hydraulic conductivity of72 core samples from 27 sites. Data were compiled largely from the literature and from data flles of the USGS, GaEPD, South Carolina Department of Health and Environmental Control (SCDHEC), South Carolina Depart~ ment of Natural Resources, and the St. Johns River Water Management District. Interpretations relating hydraulic-property values to hydrogeologic settings were made on the basis of available published hydrogeologic data.
Description of Study Area
The GaEPD defmes the coastal area of Georgia (fig. 1) to include the 6 coastal Georgia counties and 18 adjacent inland counties; a 24-county area of 12,240 square miles (mi2). To facilitate the development of ground-water models for the coastal area, the study area was expanded to include natural hydraulic boundaries that lie outside the 24-county area-an additional44 counties. The 68-county area encompasses an area of 32,660 mi2 and includes 56 counties in southern Georgia, 7 counties in southeastern South Carolina, and 5 counties in northeastern Florida.
The study area is located in the Coastal Plain physiographic province {Clark andZisa, 1976). For discussions in this report, the Coastal Plain has been divided into the upper Coastal Plain, comprised of the Fall Line Hills District of Clark and Zisa (1976); and the lower Coastal Plain, comprised of the Vidalia Uplands, Bacon Terraces, and Banier Island Sequence Districts ofClark and Zisa ( 1976). Topographic reliefranges from low in the lower Coastal Plain to steep in the northern Coastal Plain. Land-surface altitudes are as high as 100 feet (ft) in the lower Coastal Plain and 300 ft in the upper Coastal Plain. Land use is largely urban in industrial areas and cities such as Savannah and

Brunswick; outside of these areas, land use is a mix of forest, grazed woodland, cropland with pasture, marsh, and swampland.
Well-Identification Systems
Wells in Georgia are identified according to a system based on the USGS index to topographic maps of Georgia. Each 7Y:z-minute topographic quadrangle in the State has been given a number and a letter designation beginning at the southwest comer of the State. Numbers increase eastward and letters increase alphabetically northward. Quadrangles in the northern part ofthe State are designated by double letters. The letters "I," "0," "II," and "00" are not used. Wells inventoried in each quadrangle are numbered sequentially, beginning with l. Thus, the fourth well inventoried in the 34H quadrangle in Glynn County is designated 34H004.
The SCDHEC assigns identifiers to wells on the basis of their location as determined by use ofa latitude-longitude grid system. The entire State is divided into a grid matrix of 5 minutes of latitude and 5 minutes of longitude, forming 5- by 5-minute cells. Each cell has a corresponding number and uppercase letter(s), for example, 36Y. The 5-minute cells are further divided into a grid of twenty-five !-minute latitude by 1-minute longitude cells, each having a lowercase letter that starts with "a" and continues through "y"; for example, 36Y-e. Wells located within a 1-minute ceH are numbered consecutively; for example, the first well inventoried in 36Y-e would be assigned the number 36Y-el.
ln addition to a SCDHEC identifier, each well in South Carolina is assigned a county designation by the South Carolina Department ofNatural Resources; this consists of a three-letter abbreviation for the county name and a sequentialiy assigned number. For example, BAM-62 represents the sixty-second well that was inventoried in Bamburg County. In Florida, there is no uniform system employed to number wells; local well names or well numbers are used for identification.
Previous Studies
This report updates aquifer hydraulics data presented in reports for the Floridan aquifer system by Bush and Johnston (1988) as part of the USGS Regional Aquifer System Analysis (RASA) program. Bush and Johnston ( 1988) mapped the distribution of transmissivity of the Upper Floridan aquifer and produced a comparative evaluation of the reliability of these data (their plate 2) and a tabular compilation of aquifer-test data (their table 2). Krause and Randolph (1989) mapped horizontal hydraulic conductivity and transmissivity for the Upper Floridan aquifer and extrapolated these data into zones of similar hydraulic conductivity (their plate 7); they also presented a transmissivity distribution for the Upper Floridan aquifer based
on simulation (their plate 8). Clarke and Krause {2000) described
updates to previously calibrated ground-water flow models in coastal Georgia, including maps showing simulated transmissivity and leakance for the Upper and Lower Floridan aquifers.

4 Hydraulic Property of the Floridan Aquifer System

Brooks and others (1985) and Faye and McFadden (1986} presented data on hydraulic characteristics of clastic aquifer units that are updip equivalents to the Floridan aquifer system. Faye and Mayer ( 1996) presented maps showing model-calibrated hydraulic characteristics of equivalent clastic units. Clarke and West ( 1998) simulated ground-water flow in and around the Savannah River Site i11 South Carolina and Georgia; their model was based, in part, on aquifer tests performed and analyzed by personnel with Clemson University (Moore and others, 1993; Snipes and others, 1995a, b), and on transmissivity estimates derived from specific-capacity tests of wells and from borehole resistivity logs.
Szell ( 1993) provided a compilation of transmissivity and storage-coefficient data from analyses of aquifer tests in northeastern Florida. Aucott and Newcome (1986) and Newcome (1993, updated 2000) presented transmissivity and storage coefficients derived from aquifer-test analyses in the South Carolina Coastal Plain. Jones and Maslia (1994) compiled data from four large-scale aquifer tests conducted in the Brunswick area in Glynn County, Ga., and reanalyzed data from one test conducted during 1962-63 at the Hercules, Inc., wellfield at Brunswick.
Acknowledgments
Because this study relied heavily on the works by previous investigators, the authors of previous USGS reports containing large-scale compilations of aquifer properties were consulted regarding their interpretations. Peter W. Bush (U.S. Geological Survey), and Richard E. Krause and Richard H. Johnston {both U.S. Geological Survey retired) discussed their work and provided helpful suggestions on the approach for this study. Roy Newcome (U.S. Geological Survey retired and currently (2004] with the South Carolina Department ofNatural Resources) provided supplemental information from his published work that greatly enhanced the data coverage for the South Carolina part of the study area. Harold E. Gill and Robert E. Faye (both U.S. Geological Survey retired) provided a reinterpretation and reevaluation of the Waycross, Wayne County, Ga., aquifer test originally reported by Matthews and Krause (1984). Richard M. Spechler and Trudy G. Phelps (U.S. Geological Survey, Alta~ monte Springs, Fla.) and Paula F. Presley {St. Johns River Water Management District) provided data for northeastern Florida, including unpublished data from current investigations.

Geologic Setting
Geologic strata within the Coastal Plain physiographic province consist of unconsolidated to consolidated layers of sand and clay a.1d semiconsolidated to very dense layers of limestone atld dolomite (Clarke and others, 1990). These sediments range in age from Late Cretaceous to Holocene (fig. 2), and unconformably overlie Paleozoic to Mesozoic igneous, metamorphic, and sedimentary rocks. These sedimentary units generally strike northeast, and dip and thicken to the southeast; maximum thickness is about 5,500 ft in Camden County, Ga. (Wait and Davis, 1986). Prominent structural features in the area (fig. l ), such as the Southeast Georgia Embayment, the Beaufort Arch, and the Gulf Trough, influence the thickness of sediments.
The Southeast Georgia Embayment is a shallow east-tonortheast-plunging syncline that subsided at a moderate rate from the Late Cretaceous until the late Cenozoic (Miller, 1986). The thickness ofCoastal Plain deposits is greatest in the vicinity of the Southeast Georgia Embayment (fig. 3}.
The Beaufort Arch is centered near Hilton Head Island and trends parallel to the coast (fig. 1). The Beaufort Arch interrupts the regional southward dip of the sediments in that area. Within the area influenced by the Beaufort Arch, Coastal Plain deposits thin and are present at shallower depths than in the vicinity of the Southeast Georgia Embayment.
The Gulf Trough (figs. 1 and 3) is a zone of relatively thick accumulations of fine-grained clastic sediments and argillaceous carbonates, in which permeability and thickness of Coastal Plain deposits decrease. In this area, ground-water flow is partially impeded by the juxtaposition of rocks ofhigher permeability updip and downdip ofthe trough, with those of lower permeability within the trough (Krause and Randolph, 1989).
In addition to the aforementioned geologic features, the "Satilla Line" (fig. I) is a postulated hydrologic boundary identified by GaEPD based on a change in the configuration of the potentiometric surface of the Upper Floridan aquifer, and by linear changes depicted on aeromagnetic, aeroradioactivity,
gravity, and isopach maps (William H. McLemore, Georgia
Environmental Protection Division, Geologic Survey Branch, oral commun., 2000). This feature may have an impact on ground-water flow in the area; however, its geologic origin and nature are unknown.

HYDROGEOLOGY
A comprehensive study of the hydrogeologic framework of the Floridan aquifer system, which includes the study area, was conducted as part of the USGS R.ASA study and presented by Miller (1986); the reader is referred to that publication for details. Other useful summaries are included in Krause and Randolph (1989) and Clarke and others (1990)" The discussion that follows provides a frame of reference for the hydraulicproperty data presented herein.

Aoridan Aquifer System
The principal source of water for all uses in the coastal area ofGeorgia is the Floridan aquifer system, consisting ofthe Upper and Lower Floridan aquifers {Miller, 1986; Krause and Randolph, 1989). The Floridan aquifer system {Miller, 1986) consists of carbonate rocks of mostly Paleocene to Oligocene age that locally include Upper Cretaceous rocks (fig. 2). Thickness of the Floridan aquifer system in the study area ranges from less than 100ft where the aquifer system crops out in South Carolina to about 2,800 ft in Brunswick, Ga. (Miller, 1986).

Figure 3. Hydrogeologic section of the Florida aquifer system along dip, upper to lower Coasta! Plain, coastal Georgia (modified from Krause and Randolph, 1989). line of section is shown in figure 1.

The Upper Floridan aquifer is highly productive and consists of Eocene to Oligocene limestone and dolomite (Clarke and others, 1990). Lithologic units comprising the aquifer crop out or are near land sutface in the northwestern part of the study area (upper Coastal Plain) and near Valdosta in Lowndes County. Ga. (fig. 1), where the aquifer is under unconfined or semiconfined conditions. To the southeast (lower Coastal Plain). the aquifer becomes more deeply buried and conf'med. In this report, clastic sediments of the Upper Three Runs aquifer (FaHs and others, 1997) in the upper Coastal Plain that are hydraulically connected to carbonate deposits of the iower Coastal Plain are included as part of the Upper Flmidan aquifer (fig. 3). The transition from carbonate

to clastic deposits generally occurs north of the Gulf Trough {figs. 1 and 3).
In some areas, several distinct water-bearing zones within the Upper Floridan aquifer have been identified. McCollum and Counts (1964) identified five water-bearing zones in and
around the Savannah-Hilton Head Island area in strata that
would later be defined as part of the Floridan aquifer system; the upper two zones are part of the Upper Floridan aquifer (Krause and Randolph, l989).ln the Brunswick-Glynn County, Ga., area. Wait and Gregg (1973) identified two distinct water~bearing zones (fig. 2} in the Upper Floridan aquifer (their "principal artesian aquifer"} and estimated that about 70 percent ofthe total flow from wells open to both zones

8 Hydraulic Property of the Floridan Aquifer System

The methods of aquifer-test analysis or other methods used to estimate transmissivity are provided in Appendix A in order to qualify the estimates and the level of data reliability. Aquifertest analyses are categorized as nonleaky (Theis, 1935) or leaky (Hantush, 1960; Hantush and Jacob, 1955). Bush and Johnston {1988) noted that single-well tests may yield questionable transmissivity values when compared to those based on multiplewell tests. Consequently, the nonequilibrium, nonleaky analyses are further divided into Theis (193.5) for multiple-wen tests and Cooper and Jacob (1946) for single-well tests to provide a qualitative division of the derived estimates of transmissivity. The nonequilibrium, nonleaky analysis methods ofTheis (1935) and (or) the modified nonequilibrium analytical solution ofCooper and Jacob {1946) are (by a large margin) the most commonly used for tests conducted in the study area. In some older publications, the analysis method is not specified. In these instances, the most likely analysis method employed (based on the year of test analysis) is listed in Appendix A followed by a question mark. For aquifer tests that have both drawdown and recovery data and analysis, the transmissivity and storage coefficient entries listed in Appendix A generally are those computed from the drawdown data, unless otherwise noted. Estimates for both transmissivity and storage coefficient computed from recovery data are listed in the "Remarks" section of Appendix A.
In the Brunswick area, some selectivity was applied for aquifer-test results presented in this report. Maslia and Prowell (1990) concluded that some earlier aquifer-test analyses resulted in overestimation of transmissivity by not considering the upward vertical leakage to wells from lower water-bearing zones, a condition that has been documented in the area (Wait and Gregg, 1973). Additionally, it is possible that overestimation of pumpage may be a factor in overestimation oftransmissivity for some of the recovery tests that involved cessation of pumping at industrial weHfields in the area (L.E. Jones, U.S. Geological Survey, written commun., 1993, 2002}. As such, aquifer-test results presented in Jones and Maslia (19~4) are listed for the Brunswick area; earlier aquifer-test results were included only if they were consistent with results presented by Jones and Maslia (1994).
Verlical Hydmulic Conductivity
Estimates of vertical hydraulic conductivity were based on laboratory analyses of undisturbed core samples. Data include samples from the Upper Floridan and Lower Floridan aquifers and the overlying confming units. In publications in which laboratory analyses ofcores are presented, some depth intervals are given without assigning the laboratory result to a specific hydrogeologic unit. For these cases, depth intervals were assigned to a specific hydrogeologic unit during this study on the basis ofcorrelating the altitude ofth.e sampled interval with maps showing the altitude of tops of hydrogeologic units as described and mapped by Miller (1986) and Clarke and others (1990).
Laboratory analyses of core samples are limited by (1) very small sample size relative to field conditions, and (2) bias

toward more competent rock samples because core from fractured, solution-riddled, and friable rocks typically are only pa1i:ia1ly recovered or not recovered at an. Because of these limitations, core data may not be comparable to field tests, and results ofcore analyses may be biased toward th.e iower values that reflect matrix permeability rather than secondary permeability features,
Aquifer-Test Data Qualifiers
To help the reader evaluate the quality of aquifer-test results, qualifiers provided for analyses by Newcome (1993, 200()) and Jones and Maslia (1994) are listed in Appendix A. Newcome {1993, 2000) rated aquifer test results as follows:
E (Excellent)- Drawdown and recovery plots agree closely, or if data for only one plot is available, the plot provides a definitive value for transmissivity. Boundaries, if any, appear near to the same time on drawdown and recovety plots. Specific capacity is believable (well efficiency equal to or less than WO percent). No unexplainable extraneous effects. Discharge effectively constant.
G (Good}- Narrow range in possible solutions for transmissivity. Discharge held reasonably constant. If drawdown and recovery plots do not agree closely, then the reason is apparent. Specific capacity is believable. Few unexplainable extraneous effects.
F (Fair}- Plot of data for one phase of test may be clear but is unclear during other phases, or where only one plot is available, there may be substantially different possible interpretations. Discharge may have been poorly controlled.
P (Poor)- Plot(s) difficult to interpret or drawdown and recovery do not agree reasonably welL Extraneous effects distort plots. Discharge not held constant Discharge substantially increased or decreased near end of test, so recovery cannot be analyzed properly, There may be a substantial range in possible interpretations of the plots.
It should be noted that the Newcome (1993, 2000) rating system reflects not only the operational quality of an aquifer test, but also may be an indication of field conditions that do not fit the assumptions inherent in the analytical method.
Jones and Maslia (1994) rated aquifer-test results based on the fit of the drawdown or recovery curve to published type curves. Their definitions are as follows:
Excellent - all data points closely match the type curve.
Good- one or two data points fall off the type curve.
Fair- more than two data points fan off the type curve, making determination of unique match-point values questionable.
Where applicable, the Newcome (1993, 2000) and Jones and Maslia (1994) qualifiers are included in the "Remarks" section of Appendix A.

Figure 4. Boxpiot shov.ing transmissivity of the Upper ami Lower
Floridan aquifers in the study area in coastal Georgla and parts of
South Carolina and Florida, and at multi-aquifer wells cam plated in
the Upper and lower Roridan aQuifers, Duval County, Florida.

Previous studies by Maslia (1987} and Wamer and Aulenbach (1999) have shown that the Upper Floridan aquifer is anisotropic in parts of the study area. The Maslia (1987} study indicated that the Upper Floridan aquifer is anisotropic at Brunswick and Jesup, Ga., with the principal axis ofthe transmissivity tensororiented north-northeast Thedegree ofanisotropy is greateratBrunswick than at Jesup, and there is greater variability bctween local- and regional~scale tests at Brunswick than at Jesup, Local-scale tests are defmed as tests conducted using a single pumping well and one or more observation wells; regional-scale tests are defined as those involving several pumping wells (such as those that might be present at an industrial we11field} and several observation wells. Regional-scale tests encompass a larger area than localscale tests and, thus, are representative of a huger volume of aquifer materiaL Maslia (1987) attributed greateranisotropy and variability between local- and regional-scale tests at Brunswick to preferential flow along vertical solution channels associated with high-angle reverse faults and fractures similar to those described by Prowell (1985). Maslia {1987} also indicated that because of the large variation between results derived from regional- and local-scale tests at Brunswick, local-scale aquifer tests "should not be extrapolated for use in regional aquifer analyses." Warner and Aulenbach {1999) reported that the Upper Floridan aquifer is anisotropic at St Marys, Ga., with the principal axis ofanisotropy oriented north-northeast, as was reported for Brunswick and Jesup, Ga.

At Savannah, Ga., Warner and Aulenbach (1999) reported that the Upper Floridan aquifer generaHy is isotropic with an anisotropy ratio of 1.2:1. The isotropic distribution ofhydraulic properties is demonstrated by reported tran.smissivities at aquifer~test sites in the Savannah area. In 12 ofthe 13 tests reported in Chatham County, Ga,, the transmissivity ranges from 20,000
to 46,000 rt2/d, with a higher transmissivity of 80,000 rt2/d
reported at well38Ql15 {Appendix A, fig. 5b). Storage coefficient oft.i.e Upper Floridan aquifer (Appendix
A, fig. 6a-d) ranges from about 0.00004 at weH 27HH-o3 in Beaufort County, S.C., to 0.04 at "Well 1" in Baker County, Fla. The latter storage coefficient is higher than the range for a typical confined aquifer (0.0001 to O.OOI, Heath, 1983). Higher storage coefficients normally would be expected in updip areas {western and northern parts ofthe study area) where the aquifer is semiconfined or unconfined, and lower storage coefficients would be expected in downdip areas where the aquifer is more tightly confined. In parts of the study area, however, high storage coefficients have been reported in some downdip areas where the Upper Floridan aquifer is deeply buried and confined. In the Brunswick, Ga., area {fig. 6c), the wide range of storage coefficient values were attributed either to pumping interferences during testing or to vertical leakage upward from deeper zones (Jones and Maslia, 1994).
I.Dwer Aoridan Aquifer and Equivalent Clastic Unils
Transmissivity ofthe Lower Floridan aquifer and equivalent clastic units ranges from about 170 ft2/d at wel138Y-h6 in Barnwell County, S.C., to about 43,000 rt2!d at wen 33E039 in Camden County, Ga. {Appendix A, fig. 7). In northern areas where the aquifer is comprised largely of clastic sediments (Gordon
aquifer, fig. 2), transmissivity ranges from 170 to 15,000 rtlid with a median of3,500 ttl/d. In areas where the aquifer is largely carbonate, transmissivity ranges from 500 to43,000 ft2/
d. with a median of2,900 &!d.
Although no aquifer tests were conducted in wells completed solely in the Lower Floridan aquifer in northeastern Florida., it is likely that t:ransmissivity ofthe aquifer is hig!J..-.possibly exceeding 100,000 ttl/d. Krause and Randolph (1989) stated that the transmissivity ofthe Lower Floridan aquifer in the vicinity of Jacksonvi.Ue, Fla., may be as high as 400,000 Wid, hut added that their transmissivity estimates for the Lower Floridan aquifer are qualitative and primarily based on thickness and estimates ofpermeability from geophysical well logs. An estimate ofthe transmissivity of the Lower Floridan aquifer in northeastem Florida can be obtained from tests conducted in multi-aquifer production wells in Duval County, Fla, that are open to the entire thickness ofthe Upper Floridan aquifer and a hlghpenneability freshwater zone at the top ofthe Lower Floridan aquifer {Spechler, 1994). Such multi-aquifer wells are designated as "IJF, LF" in Appendix A. Spechler (1994) stated, "Although the relative contribution ofwater from each zone cannot be determined, multi-aquifer wells probably derive much oftheir yield from the upper zone of the Lower Floridan aquifer."

Figure 6c. Storage coefficient of the Upper Floridan aquifer in G!ynn County, Georgia.

Ba..o:;ed on Spechler's {1994) remarks, the transmissivity at these multi-aquifer wells is assumed to be mostly representative of the Lower Floridan aquifer (fig. 7c). Transmissivity at these multi-aquifer wells ranges from 2,100 f~/d in well D-168, to 200,000 ifld in well M503 {Appendix A, fig. 7c). The higher transmissivities in Duval County, Fla., likely are dependent on whether a solution feature is present in the vicinity of the well {G.G. Phelps, U.S. Geological Survey, oral commun., 2002).
Storage-coefficient data for the Lower Floridan aquifer are
limited to three estimates in Barnwell and Allendale Counties, S.C., and to six estimates from multi-aquifer wells in Duval County, Fla. (Appendix A, fig. 8). For the South Carolina tests, the storage coefficient ranges from 0.0003 to 0.0004. indicative ofa conftned aquifer (Lohman, 1972; Heath, 1983). The storage
coefficients for the mutti-aquifer Upper and Lower Floridan weBs in Duval County, Fla., range from 0.00002 to 0.02, with the latter value higher than the range generally cited for a confmed aquifer (Lohman, 1972; Heath., 1983). In the Brunswick, Ga., area, a similar wide range ofstorage-coefficient values for the Upper Floridan aquifer were attributed to either pumping interferences during testing or to leakage from deeper zones (Jones and Maslia, 1994).
Although transmissivity and storage-coefficient data are unavailable for the Fernandina permeable zone ofthe Lower Floridan aquifer, borehole~geophysicallogs from wells in the Brunswick, Ga., and Fernandina Beach, Fla., areas, show that iarge cavities are present in this zone, suggesting high transmissivity {Krause and Randolph, 1989; Jones and others, 2002; Phelps and Spechler, 1997). Krause and Randolph (1989) suggested that the Fernandina permeable zone may have transmis-

sivity comparable to southern Florida's "boulder zone," which
Meyer (1974) reported to be greater than 3,000,000 tt2Jd.
Vertical Hydraulic Conductivity
Estimates of vertical hydraulic conductivity for the study area are sparse and restricted to the Brunswick, Ga., area (Wait, 1965; Wait and Gregg, 1973), the Savannah River Site area {Bledsoe, 1988; Leeth and others, 1996), the Savannah-Hilton Head Island area (Counts and Donsky, 1963; Furlow, 1969), and the Port Royal Sound area (Smith, 1994). Clarke and others (1990) summarized data for the Brunswick and Savannah, Ga., areas and related values to more-current hydrogeoiogic nomenclature. vertical hydraulicconductivity data for both coruming
units and aquifer units are listed in table 1, and locations are shown in figure 9; values are plotted graphically by hydrogeologic unit :in figure 10.
Thirty-nine measurements ofvertical hydraulic conductivity for the Upper Floridan confining unit were compiled from corepenneameter analysis of samples collected at 17 sites, 12 of which are offshore of Tybee Island, Ga., and Hilton Head Island, S.C.

In addition to vertical hydraulic conductivity values compiled from core samples, Hayes ( 1979) estimated values for the Upper Floridan co11fining unit in Beaufort County, S.C., based
on aquifer-test resuits analyzed using the Hantush-Jacob leaky
aquifer analysis method (Hantush and Jacob, 1955). Although exact locations ofwell sites were not provided in the Hayes (1979) report, estimates ofver>Jcal hydraulic conductivity range from 0.005 ft!d at the Port Royal Clay Company in Port Royal, S.C., to 0.01:5 ftidat the Burton weUfieid at Burton, S.C. Hayes (1979) concluded that an average vertical hydraulic conductivity for this unit for Beaufort and Jasper Counties, S.C., would be 0.001 ftld. Estimated vertical hydraulic conductivities reported by Hayes (1979) likely are somewhat higher than actual values because the Hantush-Jacob method does not distinguish between leakage coming from units above or below an a4uifer. Thus, it is possible that some of the leakage was derived from underlying units.
Vertical hydraulic conductivity of the Upper Floridan
aquifer was compiled for five sites, three of which are located
in the Brunswick, Glyn..11 County, Ga., area (table I, figs. 9-1 0). Reported vertical hydraulic conductivity ranges from 0.00134 ftld at we1133H115 to 160.4 ftld at well34H337. Lower vertical hydraulic conductivity was measured in parts of the aquifer that are dominated by matrix permeability; higher

values occur where dissolution of rock has produced secondary permeability.
At Brunswick, Glynn County, Ga., upper and lower waterbearing zones of the Upper Floridan aquifer are separated by a semiconfining unit consisting oflow-penneability limestone (Wait and Gregg, 1973). Vertical hydraulic conductivity for this unit was determined at three sites and ranges from 0.000008 ftld at wel134H337, to 0.000134 ft/d at well 33Hl15 (table l, figs. 9-10).
Vertical hydraulic conductivity of the Lower Floridan confming unit was compiled from 10 samples at 9 sites, most of which are located in Barnwell County, S.C., :in the vicinity of the Savannah River Site :in th.e northeastern part of the study area (table l, figs. 9-10). Near the Savannah River Site, values for the Lower Floridan (Gordon) confining unit range from 0.00022 ft/d at well BW-379 to 0.16 ftld at well BW~243 (table 1, fig. 9). Elsewhere, vertical hydraulic conductivity for this unit is 0.000004 ft!dat well 34H337 at Brunswick. Ga., and 0.000668 ftld at well 36R006 near Savannah, Chatham CoUllty,
Ga. {table 1, fig. 9).
Only one estimate for the Lower Floridan aquifer is available at a well at Brunswick, Ga. (table 1, fig. 9). At well 34H337, the vertical hydraulic conductivity is 5.3 ft!d at a depth of 1,490-1 ,503 ft below land surface; this value is comparable to values for the Upper Floridan aquifer.

SUMMARY
The Coastal Sound Science Initiative is a series ofscientific and feasibility studies to support development of the State of Georgia's final strategy to protect the Upper Floridan aquifer from saltwater contamination. To support this effort, detailed information regarding the hydraulic properties of Floridan aquifer system and equivalent clastic sediments in a 67-county area ofcoastal Georgia and adjacent parts ofSouth Carolina and Florida were compiled and evaluated to provide data necessary for development of ground-water flow and solute-transport models. Data include transmissivity at 324 wells, storage coefficient at 115 wells, and vertical hydraulic conductivity of 72 core samples collected from 27 sites.
In the upper Coastal Plain, sediments equivalent to the Floridan aquifer consist of thin clastic sediments; in the lower Coastal Plain, the aquifers consist of a thick accumulation of carbonate rocks that commonly have solution features and in some places have fractures. Prominent structural features in the area-the Southeast Georgia Embayment, the Beaufort Arch, and the Gulf Trough-influence the thickness and hydraulic properties of sediments comprising the hydrogeologic units. The Southeast Georgia Embayment is a shallow east-tonortheast-plunging syncline in which Coastal Plain deposits are thickest in the study area. In the vicinity of the Beaufort Arch, centered near Hilton Head Island, S.C., Coastal Plain deposits are thinner and are at shallower depths than near the Southeast Georgia Embayment. The Gulf Trough is a zone of relatively thick accumulations offme-grained clastic sediments and argillaceous carbonates in which permeability and thickness of Coastal Plain deposits are low.

Hydraulic properties of the Upper Floridan aquifer vary greatly in the study area owing to the heterogeneity (and locally to anisotropy) of the aquifer and to the confmement (or lack thereof) provided by confining units. Transmissivity of the Upper Floridan aquifer and equivalent clastic units was detetmined at 239 wells and ranges from 530 feet squared per day (ft2/d} in Beaufort County, S.C., to 600,000 f~/d in Coffee County, Ga. In carbonate rocks of the iower Coastal Plain, transmissivity ofthe Upper Floridan aquifer generaHy is greater
than 20,000 ttZici, with values exceeding 100,000 ftZ!d in the
southeastern and southwestern parts ofthe study area {generaHy the area of greatest aquifer thickness}. Transmissivity of the Upper Floridan aquifer generally is less than 10,000 f~/d north ofthe GulfTrough where sediments comprising the aquifer, or its equivalents, are thin and consist largely ofclastic sediments, and in the vicinity of the Gulf Trough where low~permeability rocks and sediments are present.
Large variability in transmissivity in Camden and Glynn Counties, Ga., and Nassau County, Fla., indicates anisotropic distribution of hydrauHc properties, which may result from fractures or solution openings in the carbonate rocks. Storage coefficient of the Upper Floridan aquifer was determined at 106 wells and ranges from about 0.00004 in weB 27HH-o3 in Beaufort County, S.C., to 0.04 in weH 1 in Baker County, Fla. Although higher storage coefficients normally would be expected in updip areas where the aquifer is semiconfmed or unconfined, high storage coefficients have been reported in some downdip areas where the aquifer is deeply buried and confmed. In the Brunswick, Ga., area, previous investigators attributed a wide range of storage-coefficient values either to pumping interferences during aquifer tests or to leakage from deeper zones.
