The Paleozoic rocks that outcrop in Tishomingo County, Mississippi, supply water to public, industrial, and domestic wells in two counties in the northeastern part of the State. Paleozoic rocks in the area consist mostly of beds of sandstone, shale, and limestone which dip about 30 feet per mile to the southwest. The potentiometric surface of the Paleozoic aquifer slopes generally to the west away from the area of outcrop and is strongly influenced by large ground-water withdrawals at Corinth. The water level at Corinth has declined about 140 feet since 1954. Pumping at Corinth has affected water levels in wells more than 10 miles from the center of pumping. (Woodard-USGS).
