What do you know about a class of chemicals called PFAS? You can’t see them, and you can’t smell them, but they’re there, providing water-resistance and grease-proof protection to burger wrappers and pizza boxes. But PFAS are used for lots more than transporting takeout. They’re used by manufacturers in items ranging from raincoats to contact lenses to toilet paper.  And the chemicals don’t just stay in these products. When we dispose of them, they end up in our soils and waterways. And the fact that they don’t break down has earned them the name “forever chemicals.” In this episode we head to Maine to learn more about PFAS and how they have ended up in well water, on farms, in food, and ultimately in people’s bodies.Follow @foodprintorg on Instagram, Facebook, and Twitter . Stay Informed.
