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 of Anthony Ragnone Wastewater Treatment Plant: questions
Which industries discharge to Anthony Ragnone Wastewater Treatment Plant?
15 industrial users on record discharge process wastewater to Anthony Ragnone Wastewater Treatment Plant in Montrose, most of them in landfills and waste management (5), water, sewer and power utilities (4), metal finishing and plating (2). 1 are categorical users, subject to federal pretreatment standards for their industry.
Has PFAS been found in wastewater sent to Anthony Ragnone Wastewater Treatment Plant?
10 of the plant’s industrial users have been sampled for PFAS, 131 samples in 2023–2024. 9 had at least one sample with PFOS above the 12 ng/L screening level; the highest was 650 ng/L. The level is a surface water quality value, so a sample above it marks a source the plant has to follow up, not a violation by the company.
What is an industrial pretreatment programme?
Under the Clean Water Act a treatment plant that receives industrial wastewater has to control it at the source: it permits its significant industrial users, sets local limits, inspects and samples them, and reports to the state each year. The aim is to stop pollutants that pass through or disrupt the plant, or end up in its biosolids.
How do I get the full list of industrial users for Anthony Ragnone Wastewater Treatment Plant?
This page shows the first 5 of 15. The full list, with each user’s discharge flow, federal category, PFAS sampling history, source documents and contacts, is available with a free Klarifi account.
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?
