2025 Great Lakes PFAS Summit

The Michigan Department of Environment, Great Lakes, and Energy (EGLE)  hosted the 6th annual Great Lakes PFAS Summit December 2 – 4, 2025. 

Per- and polyfluoroalkyl substances (PFAS) continue to present some of the biggest challenges in chemical contamination across the world. States throughout the nation, including the Great Lakes region, are finding PFAS contamination in a growing number of locations where these persistent chemicals pose a threat to human health and the environment. The Great Lakes PFAS Summit will bring together environmental program managers, policy experts, researchers, and contractors from around the Great Lakes region to share new methods of addressing this contamination and present innovative technical solutions developed to address these “forever” chemicals.
