Potentiometric surfaces of November 1982 and declines in the potentiometric surfaces between the period prior to development and November 1982 for the coastal plain aquifers of South Carolina

Characteristics of the Coastal Plains aquifer of South Carolina are being studied as a part of the Regional Aquifer Systems Analysis program of the U.S. Geological Survey. A framework has been developed to best represent the hydrology of the State by dividing the aquifers into a system of five aquifers. This framework includes a surficial aquifer consisting of coastal terrace deposits, a limestone and stratigraphically equivalent sand aquifer of Eocene age, and three sand aquifers of Cretaceous age.
