PFAS in the Age of Uncertainty Conference

Date: March 9- 10, 2026
Location: San Antonio, Texas

Overview:

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.

The Call for Platform & Poster Abstracts is open through September 30, 2025. Click here to submit.
