The U.S. Minerals Management Service, Continental Margins Program.
The preceding repon is the final project repon of a series of technical investigations funded by the U.S. Depanrnent of Interior, Minerals Management Service (MMS), as part of the Continental Margins Program. The Continental Margins Program was created through a Memorandum of Understanding between MMS and the Association of American State Geologists, and was implemented through a Cooperative Agreement between MMS and the University of Texas; the University of Texas served as prime contractor for the Association of American State Geologists. The Continental Margins Program funded investigations by coastal state geological surveys in two areas of research:
(1) Geologic framework and petroleum related studies. The purpose of the framework studies was to develop a better understanding of the coastal-onshore, nearshore and offshore geology of the participating states with an emphasis on potential petroleum resources.
(2) Critical and strategic minerals studies. The purpose of the critical and strategic mineral studies was to identify coastal-onshore, nearshore and offshore areas where there is a potential for commercial deposits of these minerals.
The Georgia Geologic Survey participated in the Continental Margins Program for nine years. The following is a summary of the investigations performed by the Georgia Survey.

ABSTRACT
During the past ten years there has been a significant escalation of ground water withdrawal in the Georgia coastal region as a result of population growth and expanding industrial and agricultural activities. This increase in ground water use has the potential to adversely impact important aquifers in the coastal counties. Also, the possible mining of phosphate deposits on the Georgia continental shelf could seriously impact onshore aquifers. All of these factors have caused the need for a reevalution of the coastal aquifers and the potential impact of continued development on the management of ground water resources in Camden and Glynn counties in particular.
The important aquifers in these counties are: the Neogeneage surficial aquifer and the Lower and Upper Brunswick aquifers, and the Paleogene-age Floridan aquifer system. The Floridan aquifer is the major source of water for these counties. Longterm ground water withdrawal from this aquifer in the St. Marys (Camden County) and Brunswick (Glynn County) areas has resulted in lowered ground water levels and has caused salt water intrusion into the aquifer's fresh water zone. The surficial and Brunswick aquifers have the potential to provide an important supplement to the Floridan aquifer, if properly developed and protected. Depending on well location and construction, yields of 50,000 to 300,000 gallons per day are possible. The use of these supplemental aquifers could prevent or retard salt water
1

intrusion into the Floridan aquifer by significantly decreasing withdrawal rates. Also, the surface aquifer could also be used as a means of induced recharge for the Floridan aquifer. Because of their shallow depth, these aquifers should be carefully monitored for water quality and provided adequate well-head protection.

INTRODUCTION
In the coastal counties of Georgia the Paleogene-age Floridan aquifer system, previously known as the Principal Artesian Aquifer, is heavily relied on for most water uses. The recent significant rise in the use of ground water from this system primarily is the result of increased population and industry. Two counties experiencing this increased demand are Camden and Glynn, in which the cities of St. Marys and Brunswick, respectively, and are the most rapidly growing urban areas along the coast of Georgia (Figure 1). For example, the Kings Bay Naval Submarine Base established in the early 1980's near St. Marys greatly added to the water demand in Camden County.
In recognition of the stresses that increased population and industry can place on the coastal Floridan aquifer system, the need has arisen to define alternative water sources and the appropriate ways to utilize them. The purpose of this study, therefore, is to l) carry out a literature search for published and unpublished data on the Neogene-age surficial and Brunswick aquifers overlying the Floridan aquifer system of Camden and Glynn counties and 2) provide a detailed review and analysis of the Miocene to Holocene stratigraphy of the region in relation to these aquifers. The potential and possible uses of the aquifers, and threats to their water quality also is discussed.

Included as appendices to the report is an extensive file which contains information on all available geophysical, lithologic and other types of logs from wells in Camden and Glynn counties, drillers' records, hydrological test data, Intent-toDrill forms from the Public Health Departments of the two counties, and maps showing the locations of all the wells pertinent to the study area (Appendices A and B); and a bibliography of relevant literature (Appendix C). Hard copies of literature, well logs and other information were presented to the Georgia Geologic Survey under separate cover.
GEOLOGIC SETTING
Structure
The Southeast Georgia Embayment is a major structural feature that appears to have affected the deposition of sediments in the study area (Figure 2). This feature became a depositional basin in the middle Eocene, and was active through Miocene time. (Herrick and Vorhis, 1963).
In addition to the Southeast Georgia Embayment, Clarke and others (1990) identify five local structural features in the study area that have affected the deposition of sediments by causing increased and decreased thicknesses of Miocene units (Figure 2). These features are 1) a dome at Woodbine in Camden County, 2) an east-west, elongated depression in the southern part of Glynn County, 3) an east-west trending arch in east-

central Glynn County, 4) a depression that extends into Glynn County from the northwest, and 5) a depression that trends northeast/southwest under both Glynn and McIntosh counties. Brown (1984) also cites the Ocala uplift as having an effect on the thickness and deposition of middle Eocene and younger sediments.
Gregg and Zimmermann (1974) also describe three structural features in the Brunswick area that may be coincident or relate to the previously mentioned features. They also report five faults in the Brunswick area that may have resulted in some postMiocene movement.
Neogene Geology
The sedimentary units underlying coastal Georgia range in age from Cretaceous to Recent and attain a maximum thickness of approximately 1300 meters where the axis of the Southeast Georgia Embayment intersects the present coastline (Figure 2). The units dip and thicken seaward (easterly) and pinch-out toward and at the Fall Line. Pre-Neogene deposits generally are carbonates, whereas Neogene-age deposits consist primarily of sands, silts and clays.
The geologic and stratigraphic relationships described in this report are based mainly on reports by Huddlestun (1988) and Clarke and others (1990), and to a lesser extent by Herrick and Vorhis (1963) and Miller (1986) Publications concerning site

specific studies in Camden and Glynn counties include those of Wait (1965) and Gregg and Zimmerman (1974) for the Brunswick area and Glynn County; Environmental Science and Engineering, Inc. (1980) for the Kings Bay area in Camden County; Soil and Material Engineers, Inc. (1986a) for Colonels Island in Glynn County; and Westinghouse Environmental Services (1989) for the Osprey Cove Subdivision in Camden County. The Neogene stratigraphic nomenclature of the Georgia lower coastal plain is presented in Figures 3 and 4.
Miocene-Age Deposits The Miocene-age Hawthorne formation in Camden and Glynn
counties was raised to the rank of group by Huddlestun (1988) Based on this classification scheme the Hawthorne Group includes all deposits previously called Hawthorne Formation in Georgia exclusive of those strata now included in the Altamaha Formation.
The Hawthorne Group, which in Camden and parts of Glynn County overlies the Ocala Group of Eocene age, consists of three main formations: the Parachucla Formation, which is the basal unit and early Miocene in age; the late early Miocene Marks Head Formation which disconformably and paraconformably overlies the Parachucla Formation; and the middle Miocene-age Coosawhatchie Formation which disconformably overlies the Marks Head Formation.

The three Hawthorne Group formations correlate with the three depositional sequences of Clarke and others (1990) as shown in Figures 5 and 6. The Parachucla formation correlates to the C unit, the Marks Head formation to the B unit, and the Coosawhatchie formation to the A unit. The units are based on geophysical markers found in natural gamma, point resistance electric, and neutron porosity logs. The markers distinguishing each unit are the result of the phosphatic components (a characteristic feature of the Miocene) within the basal carbonate layers of the units. Along with the basal carbonate layer, all three Miocene units have a middle clay layer, and an upper sand layer. According to Clarke and others (1990) the three layers in each of the three Miocene units are evidence of depositional sequences that are the result of cyclic transgression and regression of the seas.
Miller (1986) identifies the Miocene units as being more than 150m thick in southeastern Georgia. Soil and Material Engineers, Inc. (1986a) report the Miocene as having a thickness of 115m to 140m under Colonels Island in Brunswick.
Post-Miocene-Age Deposits The post-Miocene deposits in the study area, according to
Huddlestun (1988), consists of six main units. These are the Pliocene-age Raysor Formation (Duplin?), a Raysor equivalent sand, the Cypresshead Formation, the Satilla Formation, undifferentiated alluvial deposits, and the undifferentiated surficial sand.

Figure 6. Example of relationships among stratigraphic units, aquifers, and geophysical markers in Glynn County. Modified from Clarke and others (1990).

The Raysor equivalent shelly sand of early late Pliocene age disconformably overlies the Coosawhatchie Formation of the Hawthorn Group. Locally, the Cypresshead Formation of late Pliocene to early Pleistocene age disconformably overlies the Coosawhatchie Formation. The Satilla Formation of late Pleistocene and Holocene age overlies the Cypresshead Formation. At the top of the stratigraphic column are the undifferentiated alluvial deposits of unresolved age, and the undifferentiated surficial sands of Pleistocene to Holocene age. These units are all dominated by sand. All, with the exception of the undifferentiated surficial sands, are interbedded with clays, calcareous material, and other subordinate constituents.
In Camden County Environmental Science and Engineering, Inc. (1980) carried out a detailed study of the surface and shallow subsurface sediments in the Kings Bay area. The study revealed that from the land surface down to 18m there is a variance of loose, fine-grained sands to very dense, fine- to medium-grained sands, with firm, fine-grained sands and interfingering sandy to muddy limestones. Post-Miocene units are shown by Clarke and others (1990) to reach a thickness of approximately 60m at the Brunswick Pulp and Paper Company site in Glynn County (Figures 5 and 6) and at Kings Bay in Camden County.

HYDROLOGIC SETTING
The study area is generally subtropical, receiving yearly average rainfall of 130 to 135cm (Brown, 1984). Seventy-five to 100cm of the rain water is lost in evapotranspiration; and 12 to 25cm is lost to runoff, which is shown by Krause and Randolph (1989) as generally being lowest along the coast. The remainder recharges the surficial aquifer through seepage into the water table. This infiltration generally occurs at a high rate, due to the sandy soils in the study area (Watson, 1982).
According to Krause and Randolph (1989) the water table, which is generally a subdued replica of the land surface, fluctuates with seasonal fluctuations in rainfall. The majority of rainfall occurs in July and August in most of Georgia, with the least amount in October and November. In southeast Georgia, the rainy season extends into December. Clarke and others (1990) describe how the coastal surficial aquifer can fluctuate as a tidal response, and the Upper Brunswick aquifer fluctuates with pumping of the Upper Floridan aquifer. The fluctuations in the water table are generally less than 1.5m in Southeast Camden County (Brown, 1984). Although Brown (1984) stated that the water table is approximately 1.5m below land surface in Southeastern Camden County, Krause and Randolph (1989) report that it is generally found to be much nearer the land surface in low-lying areas, such as along streams and in marshes and swamps.
15

According to Krause and Randolph (1989) water is introduced into and the surficial aquifer through infiltration from direct rainfall, as well as from lateral movement of water or seepage from surficial bodies of water. Once in the surficial aquifer, the water moves down gradient and is discharged into streams, ponds, and other surface-water bodies (Krause and Randolph, 1989). The water from the surficial aquifer can recharge underlying confined aquifers by seepage through the upper confining layers. This occurs where the water table is above the potentiometric surface of the lower aquifers. They also cite the condition where the surficial aquifer can be recharged from the underlying confined aquifers when the head gradient is reversed. Similarly, Soil and Material Engineers, Inc. (1986a) state that the Floridan aquifer possibly supplies recharge to the Miocene aquifer system due to greater head in the Florida aquifer. The interaquifer dynamics described above are supported by Watson (1979), and Clarke and others (1990) whose studies indicate that the lower portion of the Miocene aquifer system is hydraulically connected to the upper Floridan aquifer.
COASTAL NEOGENE AQUIFER SYSTEM
Clarke and others (1990) provide a detailed discussion of the shallow aquifers within the thirteen coastal counties of Georgia. Their study is one of the principle references cited in this report. An earlier study by Watson (1979) discusses the potential and lithostratigraphic relationship of the shallow
16

aquifers in coastal Georgia. A generalized north/south cross section of the coastal aquifer is shown in Figure 7.
Ground water withdrawal rates in the Brunswick area have been estimated as being between 85 and 105 million gallons per day (Johnston, 1978; Peck and others, 1992), with chloride concentrations exceeding state and federal drinking-water standards. According to Brown (1984) ground water withdrawal rates for Camden County dropped from 40 million gallons per day in 1977 to 37 million gallons per day in 1980, with 98~ of the use in the St. Marys area. Withdrawal rates in 1990, however, are cited by Peck and others (1992) as being approximately 42 million gallons per day. This increased use was due to the development of Kings Bay Submarine Base. Krause and Gregg (1972) show that between 1880 and 1971 the potentiometric surface of the principle artesian aquifer had dropped over 23m in the St. Marys area apparently due to high water use by paper mills at St. Marys and at Fernandina, Florida.
Miocene Aquifers
According to Krause and Randolph (1989) and Miller (1986), the Miocene sediments of the Georgia coastal plain are the "upper confining unit" for the Upper Floridan aquifer, because the permeability of the Miocene units is much less than that of the Floridan aquifer system. In a later report, Clarke and others (1990) designated two aquifers in the Miocene as the Lower and Upper Brunswick aquifers.

The Lower and Upper Brunswick aquifers are being used by industry, mainly in multi-aquifer wells, and some are capable of yielding up to 200 gallons per minute. In the majority of cases, the Lower and/or Upper Brunswick aquifers are used in conjunction with the Upper Floridan aquifer. Also, the two Brunswick aquifers are used in conjunction with each other, and/or with the surficial aquifer. Because of this, little work has been done concerning the Brunswick aquifers as separate and distinct aquifers.
The Lower Brunswick aquifer was identified from deposits encountered in well 33H206 (see Figure 6 and Appendix B). Here the aquifer consists of poorly sorted, fine to coarse, phosphatic, slightly dolomitic sand of Miocene unit C. According to Clarke and others (1990) the aquifer's lower confining unit correlates with geophysical marker C, and its upper confining unit correlates with geophysical marker B. They also show in that report that the thickness of the Lower Brunswick aquifer does not include that of the confining units or the intermittent clay layers found in Miocene unit C. This would make the thickness of the aquifer less than Miocene unit C. Two maps in the report by Clarke and others show the thickness of Miocene unit C, the depths (mean sea level is datum) to geophysical marker B, the upper confining unit of the Lower Brunswick aquifer, and the lower confining unit of the Upper Brunswick aquifer.
19

The Upper Brunswick aquifer was named for deposits also found in well 33H206 (see Figure 6 and Appendix B) that consist of poorly sorted, fine to coarse, slightly phosphatic and dolomitic quartz sand contained in unit B. The aquifer's upper and lower confining units correlate with geophysical markers A and B, respectively. In defining the thickness of the aquifer, the confining units or the intermittent clay layers in unit Bare not included. Therefore, the thickness of the aquifer is slightly less than the stratigraphic unit itself. Clarke and others (1990) show depths (mean sea level is datum) to geophysical marker A, which is the upper confining unit of the Upper Brunswick aquifer, and the lower confining unit of the surficial aquifer in Pliocene to recent sediments.
Pliocene to Recent Aquifers
According to Clarke and others (1990), the aquifers in the Pliocene to recent series consist of sands with interfingering layers of limestones and clay layers that can act as confining units. Clay is the confining unit for the deeper portions of the surficial aquifer in the Brunswick area, while in Camden County the deeper portions are confined by a carbonate and clay layer. Environmental Science and Engineering, Inc. (1980) designated the aquifer in this stratigraphic series as the water table aquifer, while Westinghouse Environmental Services (1989) named it the Plio-Pleistocene aquifer. Clarke and others (1990) named it the surficial aquifer.
20

According to Clarke and others (1990) the surficial aquifer is found above geophysical marker A, and includes the upper sand of Miocene unit A, as well as interfingering sand, clay, and limestone of the post-Miocene units. The overall thickness of the aquifer is slightly less than the combined thicknesses of the Miocene unit A and the post-Miocene unit. The surficial aquifer is confined at the bottom by limestone, dolomite, and clay of the Miocene unit A. The aquifer is mainly under water-table conditions, but artesian flow can be caused by locally occurring, upper confining units of clay layers or thin limestone beds. This is usually found where the aquifer is thickest due to the greater extent of the clay layers within the thicker areas.
The surficial aquifer is extensively used. This aquifer is utilized mainly for domestic use by private well owners, probably due to the greater cost of drilling deeper wells. Wait (1965) reports that wells (less than 15m deep) in the "Pleistocene sands" yield water that is used primarily for watering lawns and irrigation. Watson (1979) states that 80% of private homes in the study area receive water from the Neogene aquifer system.
NEOGENE AQUIFER SYSTEM IN CAMDEN COUNTY
Miocene Aquifers
A study by Westinghouse Environmental Services (1989) shows that the Miocene aquifers are not greatly developed in Camden County where the system includes strata from approximately 34m to
21

about 152m. In a test well in the Osprey Cove Subdivision (OC1), they identified three main zones capable of yielding significant amounts of water, as well as several minor zones. The three main zones were reported as being artesian and are at depths of 73-82m, 102-113m, and 129-142m, respectively. The "secondary artesian aquifer" of Environmental Science and Engineering, Inc. (1980) consists of a group of isolated, Miocene-age limestone lenses of variable thickness and extent that roughly correlate with the zones of Westinghouse Environmental Services (1989). These lenses fall within depths of approximately 30m to approximately 165m in the Kings Bay area.
In Camden County the depth to geophysical marker A varies from 55m near Woodbine to 109m on Cumberland Island. The depth to geophysical marker B varies from 91m near Woodbine to 133m in Northern Camden County along the Little Satilla River and to approximately 127m in the St Marys area (Figure 5). Thickness of unit B varies from 30m to 42m. The thickness of unit C varies from 15m to 18m in the St Marys area to 33m just north of White Oak and on the northern tip of Cumberland Island.
Westinghouse Environmental Services (1989) do not recommend the use of the Miocene aquifers for the Osprey Cove Subdivision, citing low permeability, high variability of hydrogeologic characteristics in the St. Marys area, and the more complex construction methods needed (screens, gravel packing, etc.) for proper implementation. They reported transmissivities of 30 to

150 square feet per day in the clearer sand portion (76-78m) in zone 1 and a transmissivity of 80 square feet per day in zone 2 and 3 combined. A hydraulic conductivity was reported by Herndon (1990) that varied from 34 to 94 feet per day.
Pliocene to Recent Aquifers
Of the three aquifers identified in the Kings Bay area by Environmental Science and Engineering, Inc. (1980), the top aquifer is the water table aquifer. In the west of their study area this aquifer has sands 12 to 90m thick. In the east of their study area it consists of sands 12 to 18m thick, underlain by 18m of limestone which thins in a westerly direction. This aquifer is generally a low-yield aquifer, with pumping capacities of 10 to 15 gallons per minute. According to that report the water is being used only for showers and latrines, and not as a potable source. The report shows five shallow wells (A,B,C,D, and E) that were set up in the Kings Bay area, at depths of 5m to 6m, to monitor the water table aquifer.
In their Plio-Pleistocene aquifer, Westinghouse Environmental Services (1989) cites water-bearing sand and shell beds and low permeability clays that are confining beds, with a lower confining unit of thick green phosphatic clay (characteristic of the Miocene). They report two permeable zones in this aquifer, with the lower being confined, and having a higher permeability (both have relatively low permeability).
23

The first zone is mainly under water table conditions and is between the depths of 0 and 12m. This zone consists of 9-12m of tan to gray very fine to fine quartzose sand; clayey quartzose sand; and tan and gray, silty sandy, and plastic gray clay. The lower zone is under confined conditions and is between depths of 25 to 34m. This zone consists of clayey, quartzose sand and sandy and clayey limestone and shells. In that report these two permeable zones are shown to be separated by a clay-bearing zone of low permeability that is 12m thick.
The hydraulic properties of aquifers in the Pliocene to recent series in Camden County are cited in a number of reports. Brown reports a transmissivity in the surficial aquifer near Kingsland of approximately 700 square ft per day. Westinghouse Environmental Services (1989) shows a transmissivity of 27 square ft per day, and a hydraulic conductivity of 0.9 ft per day in their 25-34m zone in the St. Marys area. Herndon (1990) reports hydraulic conductivity values of 21 ft per day in the surficial aquifer on Cumberland Island. That same report shows a transmissivity of 235 to 650 square ft per day in the PlioceneMiocene aquifer (18m below land surface and 10m thick). A hydraulic conductivity of 100 ft per day in the Pliocene sand is also reported.

NEOGENE AQUIFER SYSTEM IN GLYNN COUNTY Miocene Aquifers
In an early study, Mccallie (1908) reported artesian flow from a well in Brunswick coming from depths of 92m and 130m, which correlate with the Miocene section in that area. Wait (1965) identified three zones of flow in wells in the Brunswick area. Of these three zones, the first flow and the second flow occur in sediments approximately 106m and 132 to 144m deep, respectively. These depths also fall within Miocene strata in the study area. The depths appear to correlate with the artesian zones of Mccallie (1908), the Upper and Lower Brunswick aquifers, and with zones 2 and 3 of the OC-1 test well in Camden County. In 1986 Soil and Material Engineers, Inc. (1986a), reported, along with less significant aquifers in the upper 30m of the Miocene section, the presence of confined aquifers within the Miocene under Colonels Island. These are the "upper Hawthorne aquifer" (10 to 15m thick), and the "basal Miocene aquifer" (25 to 35m thick), which appear to correlate with the Upper and Lower Brunswick aquifers also.
Based on the maps in Clarke and others (1990), the thickness of unit C ranges from 30m in an area between Pyles Marsh and Thalmann to 48m on Jekyll Island. In the Brunswick area the thickness varies from 36 to 39m. The depth to geophysical marker B varies from 109m in the Brunswick area to 152m north of Sterling. The thickness of unit B varies from approximately 33m in the Brunswick area to 55 to 60m in West Glynn County. Depths
25

to geophysical marker A range from about 67m in the Brunswick area to l09m in two areas, near Pyles Marsh and just north of Sterling.
Values on hydraulic conductivity of the aquifers within the Miocene are provided in a report on two wells by Soil and Material Engineers, Inc. (1986a). The Miocene aquifers (their Basal Miocene aquifer) under Colonels Island show a permeability of 50 feet per day and a transmissivity of 2000 and 4700 square ft per day. Values for their Upper Hawthorne aquifer include an estimated permeability of 25 to 50 ft per day and a transmissivity of 900 square ft per day.
Pliocene to Recent Aquifers In the Brunswick area, Wait (1965) identified the sediments that yield water in the first 15m as medium-grained sand found at depths of 4 to 5m and 11 to 15m. That report also recognizes wells approximately 30 to 55m deep as being in post-Hawthorne sediments. Some of these wells were under artesian conditions, with water coming from gravelly sand and thin limestone beds.
The deeper aquifers in this series were identified by Soil and Material Engineers, Inc. (1986a) as being the Pliocene aquifer system, which they found to underlie all of Colonels Island in Glynn County. This aquifer, which they stated as not being utilized as a source of ground water, has a thickness ranging from 12 to 21m. They cited the Pliocene at Colonels Island as consisting of interbedded and alternating beds of
26

fossiliferous sandy limestone, calcareous sand and sandy-marly clays. The Pliocene aquifer system is recharged by the overlying Pleistocene aquifer system, which is in turn recharged by rainfall.
The sediments of the Pleistocene aquifer system are relatively thin and also were reported as not being used as a source of water on Colonels Island. The Pleistocene sediments, which have a thickness of about 8 to 14m, are unconsolidated fine- to medium sands and shell beds with thin discontinuous beds consisting of clay and silt. Watson (1979) reported a layer of coarse and fine gravel at the base of surface sediments in the majority of Glynn County. That report identifies the layer as being 9 to 50m below land surface, with a thickness varying from 2 to Sm. In the report by Clarke and others (1990) the combined thickness of Miocene unit A and the post-Miocene unit varies from approximately 70m in the Brunswick area to 121m in the Pyles Marsh area, where there is an east-west trending structural depression (Figure 2).
Very little work on the hydraulic properties of the aquifers in the Pliocene to recent series in Glynn County has been reported. Both the shallower (4 to Sm and 11 to 15m) and deeper (30 to 55m) wells in the report by Wait (1965) were found to give yields of 5 to 20 gallons per minute. In the Brunswick area, Gregg and Zimmerman (1974) show a transmissivity of 6700 square ft per day in the Pliocene.
27

GUIDELINES FOR AQUIFER USE
The shallow aquifers have been noted as possible alternatives to the Floridan aquifer system, if properly developed and used to a greater extent. Their further development and use could aid in redistributing stresses placed on the coastal aquifer systems, which would possibly help minimize cones of depression in the upper Floridan aquifer (Watson, 1979). The possible use of water in the shallow aquifers for induced recharge to hinder saltwater encroachment in certain coastal areas was recognized by Callahan (1964) and is illustrated in Watson (1979). This is accomplished by using gravity connector wells. The shallower aquifers are connected to lower aquifers (e.g. Floridan aquifer system) by these wells, allowing water to flow from shallower to deeper aquifers under the force of gravity.
The ground water in the study area is generally considered to be suitable for most uses, including irrigation and as a potable source. However, due to the shallow nature of these aquifers, they are vulnerable to water quality degradation from pollution from sources associated with industry and agriculture. It is most important, therefore, that wells be closely monitored for possible contamination to prevent the spread of pollutants within the aquifer. The sources of contaminants are numerous and include infiltration of irrigation water and water from septic tanks (Brown, 1984). Although such pollution is a greater threat
28

to the surficial aquifer than to the aquifers in the Miocene, induced recharge, poor quality water or contaminants may be introduced from the surficial aquifer into a deeper aquifer. Conversely, water quality in the shallow aquifers near the coast and on barrier islands may be harmed through the lateral or upward migration of saltwater underlying the freshwater parts of the aquifer (Brown, 1984). Miller and others (1978) recognize the problem of contamination and also show that ground disturbance, by phosphate mining, "borrowing", and other excavating activities can affect the water table. Although the water table would readjust to the new topography after disturbance, seasonal fluctuations would be greater under the new conditions.
Another important factor in dealing with shallow aquifers is that of proper well construction. Special considerations must be given the shallow aquifers in Glynn and Camden counties because of the unconsolidated sediments that compose these aquifers and their general low productivity. As stated by Watson (1979), these problems can be overcome by the use of well screens to prevent well collapse in unconsolidated sediments, and the technique of filter packing, which is helpful in increasing well yield in very fine grained sediments. Another way of enhancing well yield in the shallow aquifers is that of tapping several permeable zones with one well.
29

SHALLOW WELLS IN THE STUDY AREA
The shallow wells in Glynn and Camden counties provide for a variety of uses ranging from public supply to irrigation, most wells are used for domestic purposes. According to Watson (1979), the most common type of well in the surficial sediments is the driven or jetted well. While this type of well is economically advantageous to the private homeowner, it is very vulnerable to surface contamination.
Based on information gathered from federal, state, and county agencies, this report probably accounts for a majority of the existing shallow wells in the study area. However, it is suspected that many more shallow wells are unreported. The majority of information for this report is from the Atlanta (Doraville) office of the U.S. Geological Survey (USGS). Some 264 wells were identified as shallow wells in the USGS files. Fortyfour of these are in Camden County, and 220 are in Glynn County. The information on these wells is given in Appendix A, and the locations of these wells are shown on the two maps included with Appendix Bin this report. Due to overlapping locations of some wells, not all are shown on the map (mainly in the Brunswick area). Those that are not shown on the map are listed in Appendix A.
In addition to those on file at the USGS, 17 wells with Georgia Geologic Survey (GGS) identification numbers are listed in Appendix A. Nine of these are in Camden County, and 8 are in
30

Glynn County. Also, 1,034 copies of intent to drill forms for shallow wells were obtained from the Glynn and Camden County Public Health Departments. Six hundred three were obtained from Camden County, and 431 were obtained from Glynn County. These forms are provided to the GGS under separate cover. Included in the information on the intent to drill forms are: owner, driller, size and depth of well, depth of casing, drilling date, and location by street address.
