The Huron River drains portions of seven counties in southeast Michigan. The Huron River Watershed is more than 900 square miles and consists of hundreds of tributary creeks, lakes, and the Huron River proper. The Michigan Department of Environment, Great Lakes, and Energy (then the Michigan Department of Environmental Quality (MDEQ)) began sampling intensively on the Huron River due to the city of Ann Arbor detecting per- and polyfluoroalkyl substances (PFAS) in the Huron River, which is the main source of the city of Ann Arbor’s drinking water, and the discovery of perfluorooctanesulfonic acid (PFOS) in the river at levels over the Rule 57 water quality standard of 11 ppt PFOS. The following is a timeline of PFAS investigation activities in the Huron River Watershed.
- Continue to work with the city of Wixom and Tribar to control/reduce discharges to the WWTP with the goal of meeting the Rule 57 water quality standards in Norton Creek under the IPP PFAS Initiative.
- Evaluate known sources of environmental contamination, closed landfills, hazardous waste facilities, and facilities that discharge wastewater to the Huron River.
- EGLE will continue to sample fish from selected waterbodies in the Huron River watershed and provide results to MDHHS as available.
