Michigan Dept. of Environment, Great Lakes, and EnergyThis data is used in the Tribar Release Sampling Results interactive web app ( item details ). The Michigan departments of Health and Human Services (MDHHS) and Environment, Great Lakes, and Energy (EGLE) and local officials are working together to protect residents in Monroe, Oakland, Livingston, Wayne, and Washtenaw counties following a release of hexavalent chromium to the Wixom Sewage Treatment Facility from Tribar Manufacturing in Wixom. The sewer feeds the Wixom wastewater treatment plant, which discharges to the Huron River system. Sites shown on the map represent targeted locations. Latitude/longitude coordinates may vary slightly with each visit due to on-site sampling logistics and GPS accuracy. This data was last updated 10/12/22 and shows sampling through 9/08/22. This data shows PFAS surface water results.
