We are a 501(c)(3) nonprofit organization that promotes effective broad-based advocacy for protection and preservation of the Edwards Aquifer, its springs, watersheds, and the Texas Hill Country that sustains it.
The Edwards Aquifer Ecosystem of Central Texas is one of our most valuable, irreplaceable and endangered public treasures. The EPA recognizes it as a “Sole Source” water supply. It is the only source of drinking water for millions of Texans.
It is our right and duty to preserve and protect the Aquifer, its contributing Hill Country watersheds, its great springs, and its native biodiversity for the benefit of all residents and all future generations. As individuals and community-based organizations, we invite everyone who shares the desire to preserve the Edwards Aquifer to join with us.
The Greater Edwards Aquifer Alliance has originated a comprehensive program of science, advocacy, and public engagement aimed at protecting the quality and quantity of spring flows from the Edwards and Trinity aquifers. We are in need of support to fund key projects that are currently underway.
