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.

Tap into the latest
research here at the EAA

The Edwards Aquifer Authority’s Environmental Data Portal is your gateway to today’s research, insights, and discoveries driving sustainability and innovation for the region.

There’s more going on underground than you might think 👀
This week, we’re spotlighting one of our hands-on favorites: the Aquifer Rocks Station! See for yourself how water moves through the Edwards Aquifer compared to a sand-based aquifer—it’s interactive, eye-opening, and fun for ...all ages.

And this is just one of the many stations you can touch, test, and learn from here at the EAA EOC. Come explore, experiment, and discover what’s happening beneath our feet!🌎

💌Our love for the Edwards Aquifer runs deep, and we hope yours does too, so share these sweet messages with your aquifer adorer! Be sure to tag your aquifer sweetheart below. 😍

💙You are the water to my aquifer

💙I've loved you since the aquifer began forming
...
💙My love for you runs as deep as the aquifer

💙You are as rare as the endangered species of the Edwards Aquifer

💙I need you like the San Marcos salamander's external gills need oxygen from water

💧We are back again with our aquifer conditions report from yesterday’s February EAA board meeting where Paul Bertetti, EAA Senior Director of Aquifer Science Research & Modeling, shared current readings, 10-day averages, and historical averages for J-27 and J-17 index wells as well as the ...Comal and San Marcos springflows. Also, get an update on the seasonal precipitation outlook and the U.S. seasonal drought outlook for the next couple of months.

Science needs women. And we’re proud to have so many leading the way.

For International Day of Women and Girls in Science, we’re spotlighting the some of the talented women from our agency and sharing their voices, stories, and advice.

Thanks to Bill Taylor at KENS 5 & Kens5.com for the weather update this week!🌦️ We may have some rain chances coming up, but conserving water is still key. Every drop helps keep our aquifer thriving for generations to come!💧

Tune in to our board meeting this afternoon at 1 p.m. where you will hear announcements, updates from around our agency, an aquifer conditions report, and more. Listen live here on our Facebook page or tune in via Zoom at https://edwardsaquifer-org.zoom.us/j/96044779902

🌱 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.
