Testing and Treatment

PFAS Sampling Guidance Documents

  • The State of Michigan is working proactively to identify locations where PFAS may be present as a contaminant. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) is conducting testing in drinking water, groundwater, lakes & streams, soils, sediments, wastewater, and the PFAS foam that can accumulate at lakes and rivers. EGLE 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. EGLE 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.

Lakes & Streams Sampling

Lake, Stream and Fish Sampling

  • Lakes & Streams Sampling

    The Michigan Department of Environment, Great Lakes, and Energy (EGLE) Water Resources Division (WRD) collects samples from Michigan lakes and streams. EGLE’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.

Wastewater Treatment

  • Wastewater Treatment

    The Michigan Department of Environmental Quality (MDEQ) has the responsibility to protect the public health and the environment by ensuring wastewater is properly handled and treated safely. This is achieved through a series of programs.
