Potentiometric Surface of the Upper Floridan Aquifer in the Coastal Area of Georgia, September 2000Entry ID: USGS_OFR_2005_1030
Abstract: The Upper Floridan aquifer is part of the Floridan aquifer system that
underlies most of the Coastal Plain of Georgia, southern South Carolina,
extreme southeastern Alabama, and all of Florida (Miller, 1986). The aquifer
system is one of the most productive in the United States and a major source of
water in the coastal area of Georgia. In 1997, approximately 347 million
gallons per day (Mgal/d) ... of ground water was withdrawn in coastal Georgia
mainly for industrial and irrigation purposes (Fanning, 1999).
This report shows the potentiometric surface of the Upper Floridan aquifer in
coastal Georgia for September 2000. The potentiometric surface, which
represents the altitude at which water would have stood in tightly cased wells
open to the Upper Floridan aquifer, was constructed by using water-level and
pressure measurements collected from 225 wells during September 2000. The
distribution of data used to construct the map is similar to a previously
contoured map (Peck and others, 1999) with the exception of the Jesup, Wayne
County area. In this area, a cone of depression has historically been present
due to industrial pumping of about 63.9 Mgal/d (Fanning, 2003).
