ST. LOUIS, Mich. (WOOD) — A longtime Environmental Protection Agency Superfund site has been identified as a PFAS contamination site by the Michigan PFAS Action Response Team.

On Tuesday, MPART listed Velsicol Chemical on its list of sites. The property on Bankson Street in Gratiot County was home to a chemical manufacturing plant from 1936 to 1978 when it shut down in the wake of the state’s “PBB disaster.”

The EPA has been working on the site virtually ever since, adding a slurry wall to try and contain the chemical contamination, then returning when it was deemed that more work was needed.

According to MPART, the EPA tested 74 monitoring wells last spring for PFAS. PFAS was detected in 69 of the 74 wells. One test showed 150 parts per trillion of PFHxS — perfluorohexanesulfonic acid.
