    PFAS Part 1: Definition of PFAS, where do they come from and why won't they breakdown?

    In this episode, Shelly dives into the chemistry of PFAS. They are manufactured with beautiful fluorspar and not so beautiful fossil fuels, but what about their unique chemical structure make these compounds so resistant to biodegradation? What products are PFAS in and where in the world (it's everywhere) have they ended up!?
