North and South Carolina Atlantic Coastal Plain aquifer system Completed
The Atlantic Coastal Plain sediments in North and South Carolina consist of unconsolidated sand, silts, and clays along with crystalline carbonate units of Late Cretaceous, Tertiary, and Quaternary age that unconformably overlie consolidated crystalline bedrock of Paleozoic and Triassic age.
Aquifers and confining units located in the Atlantic Coastal Plain of North Carolina and Virginia are part of the Northern Atlantic Coastal Plain aquifer system. In South Carolina, aquifers and confining units in the Atlantic Coastal Plain sediments are part of either the Southeastern Coastal Plain aquifer system or the Floridan aquifer system. The aquifer system in North and South Carolina was divided into 17 hydrogeologic units.
The data files listed below are supplemental to Groundwater Availability in the Atlantic Coastal Plain of North and South Carolina (USGS Professional Paper 1773). The report includes a description of methods used to derive the data.

This website compiles USGS resources and data related to principal aquifers including Aquifer Basics, principal aquifers maps and GIS data, and the National Aquifer Code Reference List.Regional Groundwater Availability Studies
Regional groundwater availability studies enable information about groundwater to be integrated and consistent, so that this resource can be analyzed and understood on an aquifer–wide scale. These studies provide decision–makers with a better understanding of the status and trends in the Nation's groundwater availability. - Publications
