12 ng/L is Michigan’s surface water quality value for PFOS and the screening criterion of the initiative; 170 ng/L is the value for PFOA since July 2022. Both apply to what a treatment plant discharges to a river or lake, not to what a factory sends to the sewer. An industrial user above the level has not broken a limit: it is a source the receiving plant has to follow up with sampling, a reduction plan or pretreatment.

Industrial users: PFAS sampling reports that treatment plants file with EGLE under the IPP PFAS Initiative (MiEnviro Portal), extracted by Klarifi. Values are as reported by the receiving plant; a value shared by several compounds in one sample is read as the laboratory’s reporting limit and not counted as a detection. Spotted an error?
