“Today, the U.S. Environmental Protection Agency (EPA), in collaboration with the U.S. Department of Defense (DoD), published a draft of the first EPA-validated laboratory analytical method to test for per- and polyfluoroalkyl substances (PFAS) in eight different environmental media, including wastewater, surface water, groundwater, and soils.
A partnership between EPA and the Department of Defense’s Strategic Environmental Research and Development Program has produced draft Method 1633, a single-laboratory validated method to test for 40 PFAS compounds in wastewater, surface water, groundwater, soil, biosolids, sediment, landfill leachate, and fish tissue.
Until now, regulated entities and environmental laboratories relied upon modified EPA methods or in-house laboratory standard operating procedures to analyze PFAS in these settings. With the support of the agency’s Council on PFAS, EPA and DoD will continue to collaborate to complete a multi-laboratory validation study of the method in 2022.
‘This new testing method advances the science and our understanding of PFAS in the environment, so we can better protect people from exposure,’ said EPA Administrator Michael S. Regan. ‘This illustrates the progress we can make when working with federal partners in an all of government approach. I want to thank the Department of Defense for its leadership on this issue and for working with us to achieve this important milestone.’
This draft method can be used in various applications, including National Pollutant Discharge Elimination System (NPDES) permits. The method will support NPDES implementation by providing a consistent PFAS method that has been tested in a wide variety of wastewaters and contains all the required quality control procedures for a Clean Water Act (CWA) method. While the method is not nationally required for CWA compliance monitoring until EPA has promulgated it through rulemaking, it is recommended now for use in individual permits.”…
