WELCOME TO THE GREATER EDWARDS AQUIFER ALLIANCE (GEAA)

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 Essence of GEAA

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.

GEAA Programs

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.

Under Our Feet

The Greater Edwards Aquifer Alliance (GEAA) is excited to launch “Under Our Feet“, a new interactive website designed to promote better understanding and protection of the Edwards and Trinity aquifers and, especially, the Edwards Aquifer Recharge Zone that supplies water for over 1.5 million Texans.

Realizing that very few people understand what a marvelous resource we have in our uniquely prolific karst aquifer, GEAA designed this site to encourage everyone to love this mysterious underground landscape as much as we do. “Under Our Feet” provides users with an overview of the Edwards and Trinity aquifers, karst groundwater systems, the Edwards watershed landscape, risks facing the aquifer systems, how to protect karst aquifers, and how to stay involved. Users will discover which zone of the Edwards Aquifer they live in, what that means in the groundwater cycle, what risks the aquifer is facing, and what actions they can take to protect the Edwards Aquifer. The site uses interactive maps, links, infographics, and photos to provide an engaging experience for all users.

Adults will be encouraged to “Take the Pledge” to adopt habits and practices that will protect the Edwards spring-fed streams and keep our water supply healthy. Children can “Adopt a Blind Salamander“, one of the endangered species that lives under our feet and nowhere else.
