| Abstract: | A test-drilling program to assess the potential for saline water intrusion into the freshwater zone of the Edwards aquifer in the San Antonio region was undertaken from June 1985 through May 1986. This report presents hydrogeologic data collected during the drilling and initial testing of seven test holes located at three sites in San Antonio along the interface of the freshwater zone and saline water zone of the Edwards aquifer. Wells A-1, A-2, and A-3 (site A) are located in the saline water zone, wells C-1 and C-2 (site C) are considered to be transition zone locations, and wells D-1 and D-2 (site D) are considered to be freshwater zone locations. Wells were completed with screens or open intervals at several zones within the Edwards aquifer. Hydrogeologic data are presented for wells by site location. Information regarding flow tests, water quality, geophysical logs, and lithology are provided. Continuous water level recorders have been installed on each well to establish a record of water level fluctuations. Water samples for chemical analysis are being collected monthly to establish a record of variations in water quality. (USGS) |
