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.

🚌 Well Traveled with the EAC 🚌

The Edwards Aquifer Conservancy (EAC) supports the EAA their mission to manage, enhance, and protect the Edwards Aquifer system, including their commitment to educate the community about the aquifer as a precious resource. The EAA Education Outreach ...Center, or the EAA EOC, provides free school programs and offers interactive exhibits, endangered species aquarium, native plant demonstration garden, and are committed to educating the next generation by creating aquifer stewards.

One of the ways the EAC supports this effort is by providing bus transportation grants to the EAA EOC. Since 2023, over 4,000 students visited the EOC with the help of a bus transportation grant.

The EAC provides transportation grants to schools within the EAA jurisdiction, the portion of the Balcones Fault Zone Edwards Aquifer that provides water to over 2.5 million people and covers more than 8,000 square miles across eight counties. These include all of Uvalde, Medina, and Bexar counties as well as parts of Atascosa, Caldwell, Guadalupe, Comal, and Hays counties. The students that visit the EOC are from across the entire region.

The EAC works with key partners to povide the transportation grants. In 2025, the San Antonio Water System (SAWS) and Laguna Water Supply donated funds towards the bus transportation program. SAWS collaborates with several water education partners in the region to encourage water stewardship for the next generation. According to their website, "A knowledgeable, skilled, and active youth citizenry is a key to resolving the environmental issues today and in the future," a philosophy the EAA and EAC align with. By educating students about the Edwards Aquifer system, the EAA EOC is creating aquifer stewards, who take the knowledge they learn at the education center and pass it on to others.

When youth understand the world around them, they are more likely to take action to protect it.

Big thanks to Bill Taylor from KENS 5 for this week’s weather update! ☀️

Looks like we’re in for a stretch of warm, sunny days! With no rain expected until early April. As temperatures stay high, it’s a great time to keep water conservation top of mind and do your part to protect... your aquifer.💧

Small actions make a big impact, let’s stay mindful together! 🌎✨

🌾 Happy National Agricultural Day! 🌾

The EAA region is thriving with a variety of crops, from corn, cotton, and sorghum to cucumbers, wheat, and sunflowers. Did you know that just over 50% of EAA permit holders are agricultural producers?

Through the EAA’s Groundwater ...Conservation Grant Program, local farmers are installing water-efficient irrigation systems, subsurface drip systems, and soil moisture sensors—helping protect our precious aquifer while keeping crops strong and productive.

💧 Supporting farmers, conserving water, and growing our community—today and every day.

In honor of World Water Day yesterday, we’re diving into a few surprising facts you might not know about water, and the vital role the Edwards Aquifer and groundwater plays in our everyday lives! 🌎💧

By conserving water, we play a role in protecting the aquifer that supports our ...communities, ecosystems, and future generations. And the impact goes far beyond what’s underground, the aquifer sustains wildlife above and below the surface, protecting the habitats that depend on it every day.

Every drop we save contributes to a more sustainable and equitable future. Let’s work together to conserve water, protect your aquifer, and ensure this vital resource continues to support life, for everyone. 💙
