Abstract

Continuous water level records from 152 wells and water level measurements from an additional 750 wells in Georgia during 1986 provide the basic data for this report. Hydrographs for selected wells illustrate the effects that changes in recharge and discharge have had on the groundwater reservoirs in the State. Daily mean water levels are shown in hydrographs for 1986. Monthly mean water levels are shown for the 10-yr period 1977-86. During 1986, a prolonged drought resulted in water level declines throughout the State. Annual mean water levels were from 2.7 ft higher to 17.3 ft lower than in 1985, and record lows were measured in 33 wells in the summer and fall. The 1986 lows were from 0.02 ft to 29.2 ft lower than the previous record lows. The largest declines were measured in the Clayton aquifer in the southwestern part of the State. The declines can be attributed to reduced recharge and increased pumping that resulted from below-normal precipitation during the first half of the year. Water quality samples are collected periodically throughout Georgia and analyzed as part of areal and regional groundwater studies. Periodic monitoring of water quality in the Savannah and Brunswick areas indicates that the chloride concentration in the Upper Floridan aquifer there generally has remained stable. (USGS)
