PFAS Sites and Areas of Interest
There are two major classes of firefighting foam: Class A and Class B. Class B is also called Aqueous film forming foam (AFFF) and is usually created using PFAS. It is a highly effective foam used for fighting high-hazard flammable liquid fires, like gasoline, oil, and jet fuel.

Below are the minimum laboratory PFAS analyte lists for analysis of fish, deer, and other animals, drinking water, groundwater, surface water, soil, wastewater effluent, and landfill leachate samples collected by Michigan’s Departments of Environment, Great Lakes, and Energy, Health and Human Services, Agriculture and Rural Development, and Natural Resources. The recommended minimum analyte lists for groundwater, surface water, and wastewater are found in the U.S. EPA Method 8327 and U.S. EPA Method 1633 columns. The minimum analyte list for the testing of fish, deer and other animals is marked by the fish icon.
These minimum analyte lists were developed based on the potential for these chemicals to be found in Michigan, the availability of the chemical standards used for testing, and the ability of available laboratories to test for these PFAS compounds. These lists include PFAS that can be tested for in drinking water using United States Environmental Protection Agency (U.S. EPA) Method 533 or 537.1, which are the only methods appropriate when analyzing drinking water samples. Other testing methodologies may be used to test for PFAS in other media (not drinking water).

U.S. EPA Methods 8327 and 1633 have undergone multi-laboratory validation. Method 8327 has been published under the Resource Conservation and Recovery Act (RCRA) program and is used by the EGLE laboratory to test surface water, groundwater, and wastewater. Method 1633 has also undergone multi-laboratory validation as part of the Clean Water Act (CWA) method approval process. Method 1633 was published and when promulgated in 40 CFR Part 136, only this or other methods listed in 40 CFR Part 136 will be allowed for testing conducted under the CWA, including National Pollutant Discharge Elimination System (NPDES) permits. Until U.S. EPA Method 1633 is published and promulgated, other testing methodology may be utilized such as U.S. EPA Method 8327, ASTM Method D7979, or methods approved for use under U.S. EPA’s Alternate Test Procedures program.
This list is not exhaustive of PFAS found in Michigan’s environment.
