In this week’s episode, host Daniel Raimi talks with Caroline Noblet, an associate professor at the University of Maine, about the risks and negative impacts of forever chemicals on the environment and human health. “Forever chemicals” refer to per- and polyfluoroalkyl substances (PFAS), which are a group of synthetic chemicals with extremely durable chemical bonds that have become dangerously common in water systems, consumer goods, agricultural production, and manufacturing facilities. Because PFAS chemical bonds do not break down easily, forever chemicals stick around for long periods of time. Noblet discusses policy solutions to decrease existing water contamination due to forever chemicals and limit future exposure to these chemicals, while accounting for geographic and economic differences across communities; new rules mandating the testing of public water systems for certain PFAS chemicals; and the economic implications of efforts to clean up and reduce exposure to forever chemicals.
