How can we eliminate PFAS?

In recent years, communities across Maine and the U.S. have discovered the presence of toxic chemicals called per- and polyfluoroalkyl substances, or PFAS, in their land and water. Also known as forever chemicals because they are difficult to destroy, PFAS have been incorporated in various products, including food containers, clothing, rugs, teflon pans, fabrics and dental floss, for decades. Emerging research, however, has linked PFAS to several health issues, including weakened immune systems, increased risk of obesity and multiple cancers, developmental problems in children and harm to negative effects on reproduction. Onur Apul, assistant professor of environmental engineering at the University of Maine, is researching how to eliminate PFAS. He is one of many UMaine faculty members studying these forever chemicals and ways to mitigate them, and providing technical assistance to Maine farmers and other stakeholders. In Episode 4 of Season 7 of “The Maine Question,” Apul elaborates on the origins of PFAS, the threats they pose and efforts to stop their widespread contamination.
