An enforceable drinking water standard will be an important tool for plaintiffs. Defendants will no longer be able to assert that they have not violated any federal limitations …. And with more government scrutiny … businesses can expect that the wave of recent PFAS litigation will not only continue but will likely increase across the country. 

Abstract:

The U.S. Environmental Protection Agency (EPA) announced the long-awaited proposed National Primary Drinking Water Regulation for six per- and polyfluoroalkyl substances, known as “PFAS,” on March 14, 2023. The agency anticipates finalizing the regulation by the end of 2023, and claims that it will save thousands of lives and reduce tens of thousands of serious illnesses.

The EPA has been aware of PFAS since at least the 1990s, when one farmer’s investigation into the chemicals concluded with a seminal lawsuit against multinational chemical company DuPont. A book and subsequent feature film put that lawsuit in the spotlight, and PFAS became mainstream news.

Today, PFAS claims are widely recognized as the next frontier of mass tort and environmental litigation. With the EPA poised to finally enact the first regulation of these chemicals, that frontier is ripe for exploration.

This article explores PFAS and the origin of litigation around the substances as well as the state of PFAS litigation and regulation today. It concludes with some thoughts on what to expect when it comes to PFAS litigation going forward.
