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.

🌎 From Research to Real-World Impact: EAA Scientists at GSA Connects 🌎

Our team of Edwards Aquifer Authority scientists recently joined the Geological Society of America at their GSA Connects, right here in San Antonio, to share insights on aquifer science, sustainability, and ...groundwater management.

By studying the aquifer today, we’re not just protecting the aquifer for current communities — we’re building the data and knowledge to guide policy and decision-making for future generations. 💧

Science, sustainability, and stewardship — that’s how we safeguard South Central Texas' most precious groundwater resource. Follow along to learn more about one of the most prolific groundwater resources in Texas.

Go underwater with us as we highlight aquatic habitat restoration happening in the San Marcos River!🐟🌾

Today, Kristina is on-site sharing the important work being done to conserve habitat for the endangered Fountain darter fish and Texas wild-rice plant covered by the Edwards Aquifer... Habitat Conservation Plan (EAHCP).

In 2012, the Texas Park and Wildlife Commission designated the San Marcos River between Spring Lake Dam and the San Marcos Wastewater Treatment Plant as a state scientific area (31 TAC 57.910). The San Marcos River State Scientific Area designation prohibits the uprooting or disturbance of Texas wild-rice and authorizes installation of signage and ropes around sensitive habitat to reduce impacts from aquatic recreation. The protection zones featured here play a key role in balancing conservation while also still allowing the public to access a sensitive aquatic ecosystem and enjoy the San Marcos River.💧

'Twas the day before our angel tree gift pick up, when all through the EAA, staff were grateful to give to children and senior citizens across San Antonio that are in need of Christmas gifts. Thanks The Salvation Army San Antonio Area Command for all that you do! 🎄

Jessica Quintanilla, EAA Aquifer Science Supervisor, is here to share how our agency conducts water quality research, which allows us to identify vulnerable areas within the aquifer and learn more about the intra-aquifer connections. The data collected allows us to gain more insight and implement ...sustainable practices for the benefit of the community's most precious groundwater resource. 🌍💙
