Dr. Betsy Southerland, former EPA director of the Office of Science and Technology, joins Bloomberg Intelligence Litigation analyst Holly Froum to talk about the regulatory outlook for alleged cancer-linked PFAS, also known as “forever chemicals,” found in drinking water. Dr. Southerland discusses how and why the Trump EPA may roll back Biden-era rules passed in April that designated two of the most widely studied PFAS as hazardous under EPA Superfund laws and set maximum contaminant levels in drinking water. Dr. Southerland discusses how this could impact the safety of water for years to come and how Trump’s EPA may impact legal challenges to the rules by historic manufacturers like Chemours.
