PFAS in the Age of Uncertainty Conference

March 9-10, 2026
Hilton Palacio Del Rio
200 South Alamo
San Antonio, TX

The chemistry and environmental behavior of PFAS, combined with recent and proposed regulatory actions and toxicological uncertainties, create significant challenges for groundwater management and protection. This National Ground Water Association (NGWA) conference provides a forum to share best science and state-of-the-practice approaches to address PFAS contamination while maintaining groundwater’s essential roles for drinking water, agriculture, environmental, and other purposes. The conference provides an opportunity to share lessons learned in addressing this high-profile and rapidly evolving issue.

Call for Platform & Poster Abstracts
Open through September 30, 2025

Abstracts are solicited on these general topics:

Regulations and Risk Management
