They’re called “forever chemicals” for a reason.

PFAS—per- and polyfluoroalkyl substances—are used in everything from nonstick cookware to waterproof fabrics, but their persistence in the environment has created a growing threat in our drinking water. Xindi Hu, assistant professor at the George Washington University, and Jahred Liddie, postdoctoral associate at the George Washington University, will explore how these chemicals enter our water systems, the challenges of modeling and regulating them, and the hidden inequities in who bears the greatest burden. 

Join us for an evening that dives deep into the chemistry, policy, and social inequity of “forever chemicals,” and what it will take to ensure clean, affordable water for all.
