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.

GM Powertrain Bay City, located at 100 Fitzgerald Street in Bay City, is an active automotive manufacturing facility that has been in operation since the early 1900's. Prior on-site operations included chrome, copper and nickel plating, which are activities found to be associated with PFAS contamination. As a result, EGLE requested the responsible party (GM, LLC) to sample several on-site monitoring wells for PFAS analysis.
The GM Powertrain facility is located directly adjacent to the Saginaw River. The groundwater flow direction of the site is north toward the river.
Content posted March 2021.
The surrounding area is connected to municipal drinking water.
EGLE anticipates asking GM LLC for additional sampling to further evaluate the contamination.
