EPA Publishes Draft PFAS Analytical Method for Wastewater, Source Water, and Other Media

EPA has published a draft validated laboratory analytical method to test for PFAS in wastewater, surface water, groundwater, soils, sediment, landfill leachate, and fish tissue. EPA collaborated with the U.S. Department of Defense’s (DoD) Strategic Environmental Research and Development Program to develop draft Method 1633. This single laboratory validated method can test for 40 PFAS compounds in eight media. This is the first EPA method capable of analyzing PFAS in raw water and Clean Water Act (CWA) NPDES permits down to low parts per trillion levels. EPA and DoD will continue to collaborate to complete a multi-laboratory validation study of the method in 2022. For more information on CWA Analytical Methods for PFAS, visit EPA’s website.
