SOUTHWEST MICHIGAN -- A state analysis found contamination from two highly flourinated compounds spans the Kalamazoo River watershed between Marshall and Allegan.
The Michigan Department of Environmental Quality conducted a "relatively intensive" surface water sampling initiative around the city of Parchment after high amounts of per- and polyfluorinated compounds, or PFAS, were found in its drinking water supply.
Results released to MLive/Kalamazoo Gazette show levels of PFOS and PFOA, two PFAS compounds linked to serious health effects, were found throughout the watershed.
PFOS was found in the Kalamazoo River in concentrations between 0.6 parts per trillion and 49 ppt. PFOS concentrations exceeded a state human health and aquatic life standard in samples taken near Battle Creek, Parchment and Otsego.
Department of Environmental Quality personnel from the Kalamazoo district office collected water samples from ponds, stormwater drains and abandoned water treatment facilities at a closed paper mill in Parchment from Aug. 6-7.
