This past August, EPA published Draft Method 1633 – Analysis of Per- and Polyfluoroalkyl Substances (“PFAS”) in Aqueous, Solid, Biosolids, and Tissue Samples by LC-MS/MS.  Once, finalized, this single laboratory validated method will be available for 40 PFAS compounds (including Perfluorooctanesulfonic acid (PFOS), Perfluorononanoic acid (PFNA), Perfluorooctanoic acid (PFOA), and Perfluorobutanesulfonic acid (PFBS)) in…

In September, EPA set forth its latest draft plan for setting guidelines for PFAS limitations in industrial wastewater in certain industries, and October brought public comments on the draft.  Among EPA’s next steps in its September 2021 Preliminary Effluent Guidelines Program Plan 15 (Preliminary Plan 15) are:
