The basic geohydrology of the Edwards aquifer in the Balcones fault zone is, by now, well understood and has been capably described by many authors, especially Arnow (1959), Abbott (1975), Maclay and Small (1984), and Senger and Kreitler (1984).ONCLUSIONS AND RECOMMENDATIONS. 1. There are two Edwards aquifers in Texas, one in the Edwards Plateau and the second in the Balcones fault zone area. Both are fractured, cavernous aquifers developed in carbonate rocks that were deposited in very shallow-marine shelf environments.
