Water levels and salinities of water within the Evangeline Aquifer in an area southwest of Corpus Christi, Texas

During 1982, about 275 wells located in a 4,680 square-mile area southwest of Corpus Christi, Texas were measured to determine water-levels and specific conductance of water in the Evangeline aquifer. A large cone of depression with a maximum depth of 200 feet below NGVD of 1929 was identified near Kingsville. This cone of depression affects most of Kleburg County and parts of other counties.

Specific conductance, indicating the salinity of collected water samples, ranged from 940 micromhos per centimeter to 6,900 micromhos per centimeter. High values of specific conductance may be due to failure of well casings. Well casing failure is suspected in a few other wells also.
