Episode notes

PFAS chemicals are a class of about a thousands of chemicals that were invented in the 1930s. The EPA is finally going to regulate them and would require water utilities to clean any detectable level out of their systems. It's either 98 or 99% of Americans have some forever chemicals in their blood.

The chemical manufacturer 3M will pay $10 billion to settle claims it contaminated drinking water with “forever chemicals.” Good thing we already spoke with Barbara Moran, WBUR’s climate and environmental correspondent, who explained these non-stick chemicals that stick around forever.

This episode was produced by Avishay Artsy, edited by Amina Al-Sadi, fact-checked by Laura Bullard and Haleema Shah, engineered by Paul Robert Mounsey and Patrick Boyd, and hosted by Sean Rameswaram.
