School’s Out for Summer, but EPA’s Latest PFAS Drinking Water Health Advisory Order is No Vacation for the Regulated Industry or Litigants

If you drink water, pay a water bill, or watch the news, you’ve undoubtedly heard or seen (but were likely unable to pronounce) the acronyms for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), two of the most recognized compounds within the family of per- and polyfluoroalkyl substances.

Known as PFAS compounds, they were used pervasively in American manufacturing dating back to the 1940s and assumed the nomenclature “forever chemicals” because of their remarkable and arguably useful ability to not decompose. PFAS’ unique resistance to breaking …

Can Product Labels Be Used to Predict the Presence of PFAS? A New Study Says “Likely” for Stain- and Water-Resistant Marketed Products; Less Likely for “Green” Marketed Products

“How Well Do Product Labels Indicate the Presence of PFAS in Consumer Items Used by Children and Adolescents?” is the name of a new study published last week by the American Chemical Society, in Environmental Science & Technology. Focusing on children’s’ products, the study’s abstract states that because “product labels rarely list chemical additives, including PFAS,” the authors “evaluated whether other information on product labels can be used by consumers to select products without PFAS.”

“The primary goal of this study was to investigate …

U.S. EPA Takes Key Step Toward Regulating PFOA and PFOS

As the virus pandemic has consumed our daily news, even some of the most important developments in the environmental world seem to have floated under the radar. Last month, the U.S. Environmental Protection Agency (EPA) issued an initial regulatory determination under the Safe Drinking Water Act (SDWA) for perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)—the two most notorious substances in the family of thousands of similar “forever chemicals” also collectively referred to as PFAS. 

The EPA’s announcement—a little over a year following its release of …
