"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."
