Ground-Water Conditions in Georgia, 1996

U.S. Geological Survey Open-File Report 97-192, 101 pages

ABSTRACT

Annual mean ground-water levels in Georgia in 1996 ranged from 9.8 feet (ft) lower to 1.8 ft higher than in 1995. Of the 71 wells summarized in this report, 7 wells had annual mean water levels that were higher, 60 wells had annual mean water levels that were lower, and 4 wells had annual mean water levels that were about the same during 1996 as during 1995. Record-low daily mean water levels were recorded in one well tapping the upper Brunswick aquifer, four wells tapping the Upper Floridan aquifer, two wells tapping the Clayton aquifer, and one well tapping a Cretaceous aquifer. These record lows were from 0.1 to 11.4 ft lower than previous record lows.

Chloride concentration in water from the Upper Floridan aquifer in most of coastal Georgia was below drinking-water standards established by the Georgia Department of Natural Resources and the U.S. Environmental Protection Agency. In the Savannah area, chloride concentration has not changed appreciably with time. However, chloride concentration in water from some wells that tap the Floridan aquifer system in the Brunswick area exceeds the drinking-water standard.
