Ground-water data for Georgia, 1981

More than 2,000 water-level measurements made in Georgia in 1981 provide the basic data for this report. Daily mean water-level fluctuations and trends are shown in hydrographs for the previous year (1980) and fluctuations of the monthly mean water levels are shown for selected years in some observation wells in Georgia. Water-quality samples are collected periodically throughout Georgia and analyzed as part of areal and regional ground-water studies. Along the coast, chloride concentrations have remained stable around Savannah, but invasion of brackish water into the aquifer at Brunswick has increased the chloride concentration. Mean annual water levels throughout Georgia ranged from 3.42 feet higher to 12.68 feet lower in 1981 than in 1980, and in some areas were the lowest on record.
