Groundwater conditions in Georgia, 2003
The U.S. Geological Survey continuously monitors groundwater levels in a network of wells com-pleted in major aquifers in Georgia. This network includes 18 wells in the surficial aquifer, 15 wells in the upper and lower Brunswick aquifers, 64 wells in the Upper Floridan aquifer, 13 wells in the Lower Floridan aquifer and under-lying units, 12 wells in the Claiborne aquifer, 1 well in the Gordon aquifer, 11 wells in the Clayton aquifer, 12 wells in the Cretaceous aquifer system, 2 wells in Paleozoic-rock aquifers, and 7 wells in crystalline-rock aquifers. Data from these 155 wells were evaluated to determine whether mean-annual groundwater levels were either within, below, or above the normal range during 2003, based on summary statistics for the period of record. Infor-mation from these summaries indicates that water levels in 120 of the 155 wells (77 percent) monitored during 2003 ranged from predominantly normal to above normal.
