Two years after the EPA found high levels of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) contamination in the drinking water at the K-12 tribal school on the Leech Lake Reservation, students and staff are still forced to consume only water brought in from outside the building. Leech Lake is one place tribes are having to respond to the presence of PFAS, a class of man-made chemicals used in fire suppressing foam, water repellents on textiles, and older nonstick cookware. High PFAS exposure is connected to some health problems including cancer and thyroid disease. Nearly 100% of Americans have PFAS in their body. Information specific to Native Americans is limited. We’ll talk with some tribes that are trying to address PFAS in their water and explore what can be done.
