| Abstract: | Continuous water-level records from 144 wells and water-level measurements from an additional 617 wells in Georgia during 1988 provide the basic data for this report. Daily mean water-level hydrographs for selected wells illustrate the effects that changes ln recharge and discharge have had on the ground-water reservoirs in the State during 1988. Monthly mean water levels are shown for the 10-year period 1979-88. Maps showing the potentiometric surface of the Upper Floridan aquifer for Hay 1988 and the Claiborne and Clayton aquifers for October 1988 also are presented.
Annual mean water levels in Georgia generally were below those measured in 1987; water levels ranged from 6.9 feet higher to 7.3 feet lower. Record-low water levels were measured during the last half of 1988 in 18 wells tapping the crystalline rock aquifer, the Cretaceous rock aquifer system, the Midville aquifer system, and the Clayton, Upper Floridan, and upper Brunswick aquifers. These record lows were from 0.1 to 1.4 feet lower than the previous record lows. A prolonged drought resulted in decreased recharge to the aquifers and increased ground-water pumping, which caused water levels to decline.
Water-quality samples collected periodically throughout Georgia are analyzed as part of areal and regional ground-water studies. Maps showing chloride concentrations in the Upper Floridan aquifer in October 1988 in coastal Georgia and in the Savannah and Brunswick areas are presented. Periodic monitoring of water quality in the Savannah and Brunswick areas indicates that chloride concentrations in the Upper Floridan generally have remained stable. |
