Geohydrology and susceptibility of major aquifers to surface contamination in Alabama; area 9

This report delineates and describes the geohydrology and susceptibility of the major aquifers to contamination in Area 9 - Barbour, Bullock, Macon, Pike, and Russell Counties. The major aquifers in the study area are the Tuscaloosa, Eutaw, and Providence-Ripley aquifers of Cretaceous age; and the Nanafalia-Clayton aquifer of Tertiary age. The five counties constitute the primary recharge area for the aquifers which are the source of public supplies in the study area. The total withdrawals of groundwater for all uses in 1986 were estimated to be about 14 million gallons per day. Areas of water level declines in the Tuscaloosa aquifer have developed near Eufaula and Union Springs. Water levels in the Eutaw aquifer have declined at Union Springs. All recharge areas for the major aquifers are susceptible to contamination from the surface. Shallow wells in the outcrop area are most susceptible.
