EAA SHOWCASES SUSTAINABILITY RESEARCH AT GSA CONNECTS 2025

Each year, the Edwards Aquifer Authority (EAA) participates in the Geological Society of America (GSA) Connects meeting to share innovative geoscience research and collaborate with experts from across the country. This year’s GSA conference was held October 19–22 in San Antonio. EAA’s Aquifer Science Research and Modeling team partnered with GSA Connects Cast, an event video production company, to produce a five-minute video highlighting our ongoing research initiatives. The video features staff interviews and footage from the EAA Main Office, Camden Laboratory, and Field Research Park, and showcases three sustainability-oriented case studies:

• Modeling Aquifer Sustainability Under a Changing Climate -- Using AI and machine learning, we integrate regional climate projections to predict future recharge rates, water levels, and springflows, helping us better prepare for drought and evaluate mitigation strategies. • Measuring the Impacts of Nature-Based Land Management -- Through long-term monitoring at the Field Research Park, we use tools like geophysics, drones, and soil instrumentation to understand how nature-based solutions can improve water quantity and quality.

• Tracking Emerging Contaminants in a Growing Region -- With development increasing near the aquifer’s recharge zone, we study emerging contam inants like PFAS and wastewater impacts, combining expanded water quality monitoring with hydrogeologic modeling to better understand how pollutants move through this complex karst system. In addition to the video being shown at GSA Connects, EAA had a strong presence at the conference. EAA staff hosted a technical session on the Edwards Aquifer, led and participated in field trips, and delivered numerous talks throughout the conference, capitalizing on more opportunities to share our work and collaborate with the broader geoscience community.
