Testing and Treatment

Testing and Treatment

  • Testing and Treatment

    The State of Michigan is working proactively to identify locations where PFAS may be present as a contaminant. The Michigan Department of Environmental Quality (MDEQ) is conducting testing in drinking water, groundwater, lakes & streams, soils, sediments, wastewater, and the PFAS foam that can accumulate at lakes and rivers. MDEQ is also partnering with the Michigan Department of Health and Human Services (MDHHS), and the Michigan Department of Natural Resources (MDNR) to test fish and wildlife; MDHHS works with local health departments to issue any necessary health advisories.

    Due to the widespread use of PFAS in multiple industries and products we use every day, there are specific precautions that must be taken when conducting sampling for these chemicals to avoid cross contamination. The MDEQ has developed specific PFAS sampling guidance documents for many different sample types. The state of Michigan is also committed to sharing information with residents regarding PFAS testing that is occurring throughout the state. See the navigation bar for more details on testing results.

    In addition, while much is still in the development stages, there are some treatment options available for residents who are concerned about their drinking water. In-home water filtration systems are recommended to lower the levels of PFAS in drinking water. The state of Michigan has information on in-home water treatment. For additional information, reference the Frequently Asked Questions or visit the News and Education page.

    If you have additional questions or concerns regarding testing and/or treatment of PFAS, you may contact your local health department, or call the MDEQ Environmental Assistance Center at 1-800-662-9278.

Lakes & Streams Sampling

Lake, Stream and Fish Sampling

  • Lakes & Streams Sampling

    The Michigan Department of Environmental Quality (MDEQ) Water Resources Division (WRD) collects samples from Michigan lakes and streams.  The MDEQ’s WRD expanded its regular statewide monitoring of Michigan lakes and streams to include PFAS in 2001 by sampling 21 rivers in different parts of the state for the presence of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). The sampling in Michigan found varying concentrations of PFOS and PFOA but indicated that the levels were not at concentrations of concern based on the knowledge available in 2001.
