Edwards Aquifer

The Edwards Aquifer is the life-blood of Central and South Central Texas, feeding the most prolific springs in the Southwest United States and providing vital drinking water to over 1.5 million people. The Great Springs that gush out of the Edwards Aquifer gave life to the major cities in the middle of the State of Texas (see map above). Rare and unique animal and plant life native to this region depend on clean water in the Edwards Aquifer and its Great Springs, just like people do. Please join our effort to protect this amazing natural resource that we need!
