X ABSTRACT In the Dougherty Plain district of southwest Georgia, which includes an area of about 4,500 mi 2 , ground water is used extensively for agricultural irrigation and as a source of industrial, domestic, and municipal water supplies. Most of this water comes from the Ocala Limestone, referred to as the principal artesian aquifer. Increased ground-water withdrawals for irrigation and large water-level declines during the agricultural drought of 1977 have raised concerns about the long-term potential of the ground-water system during prolonged and serious droughts. This report presents basic hydrologic and geologic data on the principal artesian aquifer and the underlying Tallahatta aquifer, and specificcapacity, transmissivity, and storage-coefficient data for the principal artesian aquifer. The data were collected in an investigation of the Dougherty Plain by the u.s. Geological Survey, made in cooperation with the Georgia Department of Natural Resources, Georgia Geologic Survey. The report includes construction, location, and other pertinent data on about 500 wells; precipitation data for nine weather stations, mainly for 1935 through 1980; lithologic descriptions of driller's samples from 46 test wells; maps showing the potentiometric surface of the principal artesian aquifer for November 1979 and May 1980; and water-quality data for the principal artesian and Tallahatta aquifers. 1 INTRODUCTION In the Dougherty Plain district and adjacent areas of the Coastal Plain province of southwest Georgia, the principal artesian aquifer is used extensive' ly for agricultural irrigation and as a source of industrial, domestic, and municipal water supplies. Ground-water withdrawals for irrigation have increased from about 15 billion gallons in 1976 to an estimated 77 billion gallons in 1980. Increased ground-water withdrawals for irrigation and large water-level declines during the agricultural drought of 1977 have raised serious concerns about the quantity of water that can be developed from the ground-water system in the Dougherty Plain during future drought periods. The Dougherty Plain and adjacent areas covered by this report comprise about 4,500 mi in southwestern Georgia and include all or parts of Baker, Calhoun, Crisp, Dooly, Decatur, Dougherty, Early, Grady, Lee, Miller, Mitchell, Seminole, Sumter, Terrell, and Worth Counties (fig. 1). This report contains basic hydrologic and geologic data for the principal artesian aquifer and the Tallahatta aquifer and specific-capacity, transmissivity, and storage-coefficient data for the principal artesian aquifer in and adjacent to the Dougherty Plain. Table 1 lists selected wells in the report area, gives construction data, and shows the type of data available for each well. The locations of these wells are shown in plate 1. The data were collected in an i nvestigation of the Dougherty Plain by the u.s. Geological Survey, made in cooperation with the Georgia Department of Natural Resources, Georgia Geologic Survey. 2 ACKNOWLEDGMENTS Appreciation is extended to the following for allowing test drilling on their properties and for their continued cooperation throughout the study: Alvin Newton, Ike M.

A 6-character numbering system is used to identify wells in tables and fig- ures. This system consists of a 3-digit number that identifies the county in which a well is located, followed by a hyphen and a 2-digit number that is the serial number of the well in that county. The table below lists the counties and their reference numbers: Baker 007 ~e 177 Calhoun 037 Miller 201 Crisp 081 Mitchell 205 Decatur 087 Seminole 253 Dooly 093 Sumter 261 Dougherty 095 Terrell 273 Early 099 Worth 321 Grady 131 The 3-digit county number has been omitted in figures that include county names. The other numbering system used in this report is the Ground Water Site Inventory system (GWSI) of the U.S. Geological Survey which catalogs ground-water stations by using a unique number for each well. The number consists of 15 digits: the first 6 digits denote the degrees, minutes, and seconds of latitude of the well site; the next 7 digits denote degrees, minutes, and seconds of longitude; and the last 2 digits are a sequential number for wells within a 1-second grid. Once assigned, a site identifi- cation number does not change even though latitude or longitude may later be corrected. 4 PRECIPITATION DATA The locations of nine National Oceanic and Atmospheric Administration (NOAA) precipitation stations are shown in figure 2. Figures 3 through 11 show monthly precipitation for 1979-80 and yearly precipitation for 193580, or as otherwise indicated for these stations. Additional precipitation data as well as temperature data may be obtained from NOAA, Environmental Data and Information Service, National Climatic Center, Asheville, NC 28801. 5 GEOLOGIC DATA A generalized stratigraphic column of the Tertiary System in the Dougherty Plain is shown in table 2. Data in this report pertain to the upper part of the Tertiary section, which includes the Tallahatta aquifer (of the Claiborne Group), the Ocala Limestone (referred to as the principal artesian aquifer), and the residuum of the Ocala Limestone (Hicks and others, 1980). Figure 12 shows the locations of wells for which lithologic data are given on 44 test wells in tables 3 through 46. 6 WATER-LEVEL DATA In the Dougherty Plain district the principal artesian aquifer is used extensively for agricultural irrigation. Because of the increased pumpage from this aquifer, the u.s. Geological Survey has made semiannual water- level measurements since 1977 in more than 200 wells tapping the principal artesian aquifer (table 47). These wells are measured in the early spring after the winter rains when water levels are usually at their highest, and again in the fall after the summer irrigation season when water levels are usually at their lowest. Plates 2 and 3, which were constructed from some of these measurements, show the potentiometric surface of the principal artesian aquifer for November 1979 and May 1980. Continuous water-level records are obtained from a network of u.s. Geological Survey observation wells equipped with automatic water-level recorders (fig. 13). These records were used to construct hydrographs showing the change in water level over time in a specific well. Sixteen hydrographs of mean daily water levels for wells in the principal artesian aquifer, mostly for March 1979 to December 1980, are shown in figures 14 through 18. Hydrographs of mean monthly water levels for two of these wells for 1971 through 1980 are shown in figure 19. Six hydrographs showing mean daily water levels in wells tapping the Tallahatta aquifer, mainly for January 1979 to December 1980, are presented in figures 20 and 21. 7 AQUIFER HYDRAULIC DATA Aquifer hydraulic data are presented in this report for only the principal artesian aquifer. Specific-capacity data were obtained by field tests conducted for the Dougherty Plain study and from the files of local drillers. Specific capacities and related data for selected wells are given in table 48, and locations of these wells are shown in figure 22. Transmissivity and storage-coefficient data were obtained from aquifer tests conducted for the Dougherty Plain study. The locations of the test sites and the calculated transmissivity and storage-coefficient values for each site are shown in figure 23. The method used to calculate the transmissivity and storage-coefficient values for each aquifer test and a listing of the calculated values are summarized in table 49. A plot and listing of the drawdown data, other pertinent data, and the calculated transmissivity and storage coefficient for each site are given in figures 24 through 34. 8 WATER QUALITY Since 1950 the u.s. Geological Survey periodically has collected and analyzed water from wells in the report area. A means of comparing the concentrations of constituents in water from the principal artesian aquifer with concentrations in water from the Tallahatta aquifer is provided in table SO. Constituent concentrations generally are higher in water from the Tallahatta aquifer than in water from the principal artesian aquifer. Water from the principal artesian aquifer, however, generally contains higher nitrate concentrations than water from the Tallahatta aquifer. Water from both aquifers generally is suitable for agricultural, municipal, domestic, and most industrial uses. 9 SELECTED REFERENCES Herrick, S.
