In the coastal area of Georgia, the Upper Floridan aquifer is the principal water-supply source. Restrictions have been placed on withdrawals from the aquifer because of declining water levels and saltwater contamination, which has prompted interest in the development of alternative sources of groundwater. At Fort Stewart in Liberty County, Georgia, a well was completed to test the surficial aquifer as a possible source of irrigation water for athletic fields. The U.S. Geological Survey in cooperation with the U.S. Army conducted an evaluation in 2010 of the water-bearing potential of the surficial aquifer. This evaluation included describing the depth, thickness, and lithology of the surficial aquifer and its geophysical characteristics, hydraulic properties, and water quality. Results of a 24-hour aquifer test indicate that the aquifer is capable of well yields in hundreds of gallons per minute of suitable quality for irrigation use.
