As their name suggests, “forever chemicals” have extraordinary staying power. When these nearly indestructible compounds find their way into our soil and water, they don’t break down for hundreds or thousands of years. PFAS – the name for these synthetic chemicals – isn’t just in our natural environment. Scientists have found it everywhere, including in the blood of nearly every living being. 

In this episode, we talk to the reporter who broke open the story about a decades-long corporate coverup regarding forever chemicals, look at what we know about their health effects, and consider how a kneecapping of the EPA’s regulatory power may weaken the best tool we have for protecting ourselves from PFAS contamination. 

Guests:

Nathaniel RichAuthor of “Second Nature: Scenes from a World Remade,” and the New York Times Magazine article, “The Lawyer Who Became Dupont’s Worst Nightmare

Rachel FrazinEnergy and Environment Policy reporter for The Hill, co-author of “Poisoning the Well: How Forever Chemicals Contaminated America
