    The Flint River drains portions of seven counties in mid-Michigan. The watershed is more than 1,300 square miles and consists of hundreds of tributary creeks, lakes, and the Flint River proper. In 2013 the Department of Environmental Quality (DEQ, now EGLE) detected PFAS in samples from the Flint River. The discovery of the elevated concentrations of PFAS in the Flint River has led to numerous investigations of potential sources and mitigation efforts, including Gilkey Creek and Lapeer Plating and Plastics. 

    The city of Flint currently obtains its drinking water from the Great Lakes Water Authority, which was tested in November 2017 and found not to have detectable levels of PFAS. For latest test results, contact the Great Lakes Water Authority directly.

Next Steps

    • EGLE is awaiting the PFAS results for fish collected from the Holloway Reservoir and the south branch of the Flint River in 2020.
    • EGLE will conduct the POCIS study in 2021 to monitor PFAS trends in the Flint River watershed.
    • EGLE will continue to monitor PFAS in fish from the Holloway Reservoir in 2021.
    • Work under the Industrial Pretreatment Program (IPP) PFAS Initiative will continue for the Flint WWTP, Genesee County Ragnone WWTP, and the Lapeer WWTP.  These municipalities will be continuing to evaluate and reduce sources of PFOS and PFOA, as well as consider local PFAS regulatory options.
