Abstract

A generalized potentiometric surface map prepared as part of a regional analysis of sand aquifer system defines the altitude of water levels under pre-development conditions for aquifer unit A4, the lowermost group of aquifers in the sand aquifer system. Aquifer unit A4, consisting of Upper and Lower Cretaceous sands, is under artesian conditions except locally in the recharge areas. The regional flow direction is to the rivers in the area where the unit outcrops and southward to the Gulf of Mexico in Mississippi, Alabama, and West Georgia. In coastal Georgia and South Carolina, the direction of flow is east northeast parallel to the coast and into North Carolina. (USGS)
