Our Purpose Runs Deep

The Edwards Aquifer is more than a water source — it’s a living story that connects our past, present and future. It’s the reason settlers came to this area, and it’s the lifeblood of our growth. Our aquifer is a resource we can study and learn from. It’s an incredible wonder, and it’s why we’re here.

🌱 Edwards Aquifer Protection Through Land Conservation 🌱

The Edwards Aquifer is one of the nation’s most productive yet vulnerable groundwater systems. The Aquifer supplies drinking water for more than two-and-one-half million people across south-central Texas and sustains iconic ...springs, including Comal and San Marcos Springs. To safeguard this critical resource, in 2000 the City of San Antonio created the Edwards Aquifer Protection Program (EAPP), which was funded through a one eighth cent sales tax approved by voters. Over the past 25 years funds raised via the EAPP have been used to protect over 150,000 acres of land through fee simple acquisitions and conservation easements.

A conservation easement is a voluntary legal agreement that permanently protects land by limiting certain types of development, while allowing the land to remain privately owned. Conservation easements on the recharge and contributing zones of the aquifer are a significant component of EAA’s fulfillment of its mission to manage, enhance, and protect the Edwards Aquifer. In addition to the EAPP and other land conservation initiatives, the EAA and the Edwards Aquifer Conservancy (EAC) hold more than 7,900 acres in easements. These lands include the Field Research Park, where EAA scientists are studying aquifer hydrology and land management techniques.

The EAA’s Aquifer Science Research and Sustainability teams support the EAPP by conducting geological assessments to help identify the most protective properties for the program and by providing annual monitoring to ensure long-term integrity on nearly 185,000 conserved acres in the region.

Edwards Aquifer Conservancy

This week’s weather report is in, and it’s a dry one. ☀️
Big thanks to Bill Taylor at KENS 5 for the update. With no rain expected over the next week, conserving water matters more than ever. Every drop we save helps protect the Edwards Aquifer, our region’s vital water source. ...Let’s do our part, smart water use today makes a real difference tomorrow.💧🌿

💧 Where water connects us 💧

Throughout the region, the EAA participates in a variety of activities that bring people together and strengthen community connection. This includes volunteer cleanups, conservation events, wellness activities, local and regional races, and the many ...informational community resource fairs where staff share aquifer knowledge with residents of all ages. The EAA also supports and speaks at conferences across Texas, helping connect aquifer science, conservation strategies, and community needs with broader regional and statewide conversations. Board members and employees alike take part in these outreach opportunities, demonstrating the organization’s commitment to showing up as active partners across the communities it serves.

Rooted in community. Rooted in conservation. 💧✨

We’re proud to highlight the January photo featured in the 2026 EAA Calendar, taken by a winner from our 2025 Rooted in Saving Water photo contest. These images showcase how families, schools, and neighbors across our region are ...putting creativity and care into conserving water and protecting the Edwards Aquifer.

In this photo by Rachel Cywinski, we see the Native Sabal Mexicana with winter precipitation. This highlights the importance of resilient multi-height plantings to prevent dehydration of foliage in extreme cold. These plants protect the ground under native trees, sheltering seedlings of spring­ blooming annuals, and providing vital refuge to urban wildlife in freezing conditions.

📅 The 2026 calendar celebrates drought-smart solutions, stewardship, and the shared commitment to keeping our water source healthy and resilient.

Stop by the EOC to explore, learn about the aquifer, and pick up your free calendar while supplies last. We love sharing your talent with every visitor who walks through our doors!
