In this episode, we expand upon the work done by high school students as part of the Society of Professional Journalists' Northeast Summer Institute. We sit down with scientists and legislators to discuss what Perfluoroalkyl and Polyfluoroalkyl Substances (PFAs) are, why they are harmful, and what policymakers are doing to prevent contamination. Listen to find out what common products these chemicals are found in and what communities are at a higher risk for exposure.
