Where is the Aquifer Located
The Edwards Aquifer is an artesian aquifer located in Central/South Texas. From the western-most reaches of our region in Uvalde County to points east in Hays County and many places in between, the Edwards Aquifer is the natural water resource that supports approximately 2.5 million people.
The Edwards Aquifer Authority is responsible for a jurisdictional area that covers more than 8,000 square miles across eight counties in south-central Texas, including all of Uvalde, Medina, and Bexar counties, plus portions of Atascosa, Caldwell, Guadalupe, Comal, and Hays counties.
