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 & 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.

Public Water Supply Information

Statewide Sampling Initiative

  • Statewide Sampling Initiative

    The Michigan Department of Environmental Quality (MDEQ) has begun a statewide initiative to test drinking water from all community water supplies for PFAS. MDEQ is taking this precautionary step of testing these drinking water sources to determine if public health actions are needed. Information on this page summarizes current sampling results from these locations.

  • In-Home Water Filtration Systems for PFAS Reduction

    Per- and polyfluoroalkyl substances (PFAS), also known as perfluorinated chemicals (PFCs), are a large group of more than 3000 man-made fluorinated organic chemicals that have been used since the 1950s in firefighting foams, oil and water repellent products, and surfactants. PFAS can be released to the environment by manufacture and use of items that have PFAS in them. PFAS in the environment may enter surface water, groundwater, and drinking water wells. Some wells may have PFAS levels, or amounts, that are high enough to cause concern for human health. For these residents, in-home water filtration systems are recommended to lower the levels of the PFAS in their drinking water.

  • Michigan's Industrial Pretreatment Program

    Pollutants in industrial wastewater may compromise municipal treatment plant processes or contaminate waters of the state.  To protect municipal treatment plants and the environment, the Pretreatment Program requires industrial dischargers to use treatment techniques and management practices to reduce or eliminate the discharge of harmful pollutants to sanitary sewers.  The Pretreatment Program is a core part of the Clean Water Act's National Pollutant Discharge Elimination System (NPDES).
