Four general methods of detecting salt-water leaks have been used. In the pumping metho

This report is based on an investigation by the United States Geological Survey, the Texas State Board of Water Engineers, and the Texas State Board of Health to determine the ground-water resources of Uvalde and Medina Counties, especially in relation to irrigation, both in these counties and in the counties to the south where water is obtained for irrigation from the Carrizo sand and younger for

The water discharged from the large springs of San Antonio and most of the deep wells of the San Antonio area comes from a common reservoir in fissures and solution channels in the Edwards limestone. The water enters the limestone in a zone of outcrop along the Balcones escarpment, which crosses the northern parts of Bexar and Medina Counties and extends a long distance both to the east and west o

Abundant supplies of fresh water are obtained from deep artesian wells In all parts of Kleberg County. The water is derived from a stratum of sand, 10 to 150 feet thick, which usually has been referred to the Goliad sand but possibly may be at the base of the LIssie formation. The top of the sand Is reached at depths of around 400 feet In the western part of the county, 600 to 700 feet In the loca
