Tackling PFAS, From Wastewater to Tap Water

Credit: USEPA

Tackling “forever chemicals” in tap water (start time: 6:11): In this week’s science show we discuss the scientific findings and societal implications of a new study showing of dangerous PFAS (per- and polyfluoroalkyl substances) in treated wastewater that ends up in the drinking water of more than 20 million Americans. We also explore the public health risks of these  cancer-causing and otherwise toxic compounds–found in so many consumer products, including water-resistant clothing–and what’s being done on the national, state and local fronts to protect source water and our health. Listen to host Susan Moran’s interview with Kate Dunlap, the drinking water quality manager for the City of Boulder; and Bridger Ruyle, a research assistant professor of environmental engineering at New York University and lead author of the new PFAS study.

From Sewage to Planet Savior?

The Power of Poop (start time: 5:41)  This potent byproduct of our digestive system holds the promise of being a big part of the solution to several public health and environmental challenges of our time, such as drinking water scarcity and degraded cropland. In this week’s show, How On Earth’s Susan Moran interviews Dr. Bryn Nelson, a science writer and former microbiologist. His debut book, called Flush: The Remarkable Science of an Unlikely Treasure, recently appeared in paperback.
