The Balcones Fault Zone Edwards Aquifer of south-central Texas is one of the most important karst aquifers in the United States and provides water to 1.7 million people and for critical habitat for endangered species. The Edwards Aquifer extends 400 kilometers from Del Rio, east to San Antonio though Austin, and northeast to Bell County. The aquifer is from 10 to 60 kilometers wide and in places, more than 1,200 meters. The aquifer is contained within the Edwards Group limestone and associated units (Georgetown limestone). The Edwards and associated units were deposited in late Early Cretaceous time and are 150 to more than 300 meters thick. The Edwards Limestone, since deposition, has undergone subaerial exposure, burial in the middle Cret...
