CWA Method 1633 for PFAS

Under the Clean Water Act (CWA), EPA, in partnership with the Department of Defense (DoD), has published draft analytical method 1633 that analyzes 40 PFAS in various media: wastewater, surface water, groundwater, soil, biosolids, sediment, landfill leachate and fish tissue.  “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….DoD expects to begin a multi-laboratory validation study of the procedure in 2021 and complete it in 2022, in collaboration with the Office of Water and the Office of Land and Emergency Management….the Office of Water encourages laboratories, regulatory authorities, and other interested parties to review and use the draft method, with the understanding that it is subject to revision.”
