The final year of the Biden administration saw several significant developments related to the regulation of per- and polyfluoroalkyl substances, more commonly known as PFAS. These developments included the U.S. Environmental Protection Agency’s designation of the two most common PFAS compounds as hazardous substances under federal cleanup laws and its limitation of six PFAS compounds under federal drinking water regulations, among others. The past year also saw a growing number of PFAS-related lawsuits, which are currently in various stages of litigation. What could happen to all these developments in 2025? Can the Trump administration change these rules and policies? What about the numerous PFAS related lawsuits that have been filed in the past year?

The term “PFAS” encompasses thousands of manmade chemicals. PFAS compounds have been widely used for decades in various applications, including manufacturing water-, stain-, and heat-resistant consumer products, e.g., waterproof clothing and food packaging, and as ingredients in aqueous film forming foams (known as AFFF) used to extinguish certain kinds of chemical fires. There is research indicating that exposure to certain PFAS, which are prevalent and persistent in the environment, may cause various health-related impacts. In an effort to address the impacts related to PFAS, in 2021, the Biden administration published a “PFAS Strategic Roadmap: EPA’s Commitments to Action 2021-2024” identifying a number of regulatory priorities that the administration planned to take during its four-year term. …
