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.

The Saginaw Malleable Iron (SMI), facility is located at 77 West Center Street and was a former automotive foundry that operated for close to 100 years. The property is over 300 acres in size and contains numerous former operational areas, including the foundation of the former plant, a railroad area, and landfill areas. Manufacturing activities included metal casting and heat treating. Due to prior use of the property, EGLE requested the responsible party (RACER Trust) to sample several on-site monitoring wells for PFAS analysis.
The former SMI facility is located directly adjacent to the Saginaw River. The property contains a storm water pond, secondary pond, and numerous wetlands. The groundwater flow direction in the former plant area is east toward the Saginaw River. The primary groundwater flow direction in the vicinity of the landfill is east toward the river, but also flows south and west toward several surrounding wetland areas.

There are no drinking water wells located on-site. A deed restriction has been filed for the site that prohibits construction of future drinking water wells. A few residential wells were identified within a 1-mile radius of the site, however, PFAS is not expected in the vicinity of the homes based on the monitoring wells sampled nearest the homes. Additional monitoring wells have been sampled to confirm this. EGLE previously confirmed municipal water service is available to all the homes in the area.
EGLE staff will continue to review PFAS results as they are received to determine what future actions may be needed.
