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.

Butterworth #2 Landfill Superfund Site is located at 1450 Butterworth Street SW. EGLE staff requested the USEPA to sample PFAS at the landfill in 2019 due to historical accounts of platers and Wolverine Worldwide disposing of waste at the Site.
PFAS sampling was included in the 2019 Five-Year Review as an issue/recommendation. Sampling at the landfill commenced in June 2024, including 22 monitoring wells along the Grand River and 3 leachate wells.
Results of the 2024 sampling effort showed multiple exceedances of PFAS in the groundwater/surface water interface (GSI). The highest PFOA concentration was 150 parts per trillion (ppt) (compared to 8 ppt), PFOS 320 ppt (compared to 16 ppt), PFHxS 74 ppt (compared to 51 ppt), and PFNA 7.1 ppt (compared to 6 ppt).
Groundwater flows from north to south, directly into the Grand River. The 120-acre landfill has several wetlands and ponds within its boundaries, including an aboveground storm water drain directing runoff from the Site into the Grand River.

On this map you will find GSI well locations with PFOS and PFOA results reported.
Residents in the area are connected to municipal water. EGLE and DHHS evaluated residential well logs and confirmed there are no residential wells downgradient of the site.
