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.
Dive into deeper discovery through education.
There’s so much to explore at the EAA Education Outreach Center. We’ve got a hub of interactive exhibits and hands-on activities designed to inspire a deeper connection to the water that sustains our region.

Earth Day is a reminder that some of our most important natural resources aren’t always visible... but they are essential to everything we do. 🌎💧
The Edwards Aquifer is one of the most vital water sources in South-Central Texas, supporting communities, agriculture, industry, and
...
unique ecosystems found nowhere else in the world. Protecting it requires thoughtful management, ongoing research, and a shared commitment to conservation.
At the Edwards Aquifer Authority, that responsibility drives everything we do, from monitoring aquifer levels and ensuring sustainable use to preserving the delicate balance of the aquifer system.
This Earth Day, we encourage everyone to take a moment to consider the role water plays in your daily life, and how small actions can help protect this critical resource for generations to come.

The Edwards Aquifer Authority (EAA) internship program gives students the opportunity to gain real-world experience while exploring careers in science, engineering, communications, policy, and other water-resource fields. Each semester, interns join teams across the organization and contribute to
...
meaningful projects that support EAA’s mission to manage, enhance, and protect the Edwards Aquifer. By working alongside staff mentors, interns build practical skills, deepen their understanding of the aquifer system, and see firsthand how science informs water stewardship in our region.
One recent group of Aquifer Science interns led a standout project at EAA’s Field Research Park, where they developed and implemented an atmospheric deposition monitoring effort from concept to completion. After researching best practices, the interns designed a site-specific sampling approach, installed collection equipment, and established procedures for ongoing monitoring and analysis at EAA’s Field Research Park. The project strengthens EAA’s ability to track airborne inputs (such as nitrates) into the aquifer. This project highlights the lasting impact interns can have on EAA science initiatives.
Aquifer Science interns also contribute to field and laboratory efforts. Recent work has included assisting with geophysical data collection at the Field Research Park, designing a method to analytically measure total suspended solids in EAA’s Camden Laboratory as part of Project SCAR, and helping build a weir to support our hydrologic monitoring. These experiences allow interns to apply classroom knowledge, develop technical confidence, and directly support our ongoing aquifer research efforts. Through its internship program, EAA invests in the next generation of water professionals while advancing its mission-driven work. Interns leave with valuable experience, mentorship, and a deeper connection to the Edwards Aquifer, which prepares them to contribute to sustainable water resource management in Texas and beyond.
