Georgia Geologic Survey Hydrologic Atlas 22
This report illustrates and describes the potentiometric surface of the Upper Floridan aquifer in Georgia and adjacent parts of Alabama, Florida, and South Carolina for May 1998, and water-Ievel trends in Georgia for the period May 1990 to May 1998. 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 waterlevel and pressure measurements collected from more than 2,000 wells during May 1-26, 1998. The potentiometric-surface map is used to better understand ground-water flow in the Upper Floridan aquifer. In addition, the potentiometric-surface map and related water-level data will be used in the development of ground-water-flow models of the aquifer system for the coastal area of Georgia.
