The hidden heart of Texas - the Edwards Aquifer Ecosystem - provides the essential life source for the people and wildlife of San Antonio, Texas. Prolific, fragile, and mysterious, the Aquifer, its contributing watersheds and its Great Springs supply drinking water for more than 1.8 million people, support recreation for millions of Texans and tourists alike, and provide habitat for more than 50 species of plants and animals that live here and nowhere else on Earth.
