Hydrogeology of the Southern Flint River Basin

Stratigraphic column for Southern Flint River Basin Surficial aquifer/upper confining unit--not a primary source of water Upper Floridan aquifer--major source of water for irrigation and domestic use Lisbon confining unit Claiborne aquifer--major source of water for public supply Wilcox confining unit--in some areas, layers in selected formations provide ample supplies for domestic use Clayton aquifer/Providence aquifer--major source of water for irrigation, industrial, and public-supply use Providence-Ripley confining unit Cusseta aquifer--forms a single aquifer with the Providence Sand and Ripley Formation downdip and eastward Blufftown aquifer Eutaw and Tuscaloosa Formations

Ground water is the principal source of water for irrigation, industry, and domestic uses in the southern Flint River Basin. Aquifers consist of layers of sand or limestone that are separated by confining units of low permeability. Discharge of water from the aquifers to wetlands, streams, and springs is vital to maintain wildlife and plant species.
