On February 8, 2024, the U.S. Environmental Protection Agency (EPA) published two proposed rules in the Federal Register that would expand the EPA’s authority to address certain per-and polyfluoroalkyl substances (PFAS) under the Resource Conservation and Recovery Act (RCRA). These rules would significantly increase the EPA’s and authorized state’s authority to address the release of

Last week EPA released its proposal for the first set of Maximum Contaminant Levels (MCLs) under the Clean Water Act for per- and polyfluoroalkyl substances (PFAS).  In contrast to non-enforceable health advisory levels introduced in 2016 and revised in 2022, MCLs constitute enforceable drinking water standards that will impact drinking water utilities and industry nationwide. 

Earlier this month, EPA set new lifetime health advisories for four per- and poly-fluoroalkyl substances (PFAS) – in some instances at levels lower than those that can be detected through laboratory testing. The new health advisories are listed below:

PFASHealth Advisory (in parts per trillion)
PFOA (perflurooctanoic acid)0.004 ppt
PFOS (perfluorooctane sulfonic acid)

On October 18, 2021, EPA Administrator Michael S. Regan announced the PFAS Strategic Roadmap: EPA’s Commitments to Action 2021-2024 (Roadmap). The Roadmap is intended to be a comprehensive approach to confronting PFAS contamination nationwide. Among many other efforts, the Roadmap includes the following planned actions:

  • Establishing a national primary drinking water regulation for PFOA and

September 2, 2021, the Environmental Protection Agency (EPA), in collaboration with the Department of Defense (DOD), released the first EPA-validated laboratory analytical method to test for per- and polyfluoroalkyl substances (PFAS) in eight different environmental media. Method 1633, currently in draft form, is a single-laboratory validated method to test for 40 PFAS compounds in wastewater,

As we previously reported, EPA published a PFAS Action Plan in 2019 designed to enhance and improve data gathering, regulatory development, enforcement, and communication related to per- and polyfluoroalkyl substances (PFAS). EPA continues to make progress implementing the PFAS Action Plan and is working on a more formal framework for addressing PFAS under the
