Ground-water data for Georgia, 1982

Continuous water level records from 105 wells, and more than 2 ,000 water level measurements made in Georgia during 1982 provided the basic data for this report. Selected wells illustrate the effects that changes in recharge and pumpage have had on the various groundwater resources in the State. Daily mean water levels are shown in hydrographs for 1982. Monthly means are shown for the 10-yr period 1973 and 1982. Mean annual water levels ranged from 10 ft higher to 1 ft lower in 1982 than in 1981. This is a significant reversal of the downward trend of the past few years. Water quality samples are collected periodically throughout Georgia and analyzed as part of areal and regional groundwater studies. Along the coast, chloride concentrations have remained stable in the Savannah area, but invasion of brackish water into the aquifer has increased the chloride concentration at Brunswick.
