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 McLouth Steel Corp. Trenton, located at 1491 West Jefferson Avenue, was added to the National Priorities List as a Superfund Site in 2019. Remedial Investigation activities led by the USEPA began in 2021. As part of the Remedial Investigation, the USEPA’s contractors completed PFAS sampling of 46 groundwater monitoring wells onsite due to the historic use of AFFF to extinguish an onsite fire. PFAS was detected in 33 of the 36 monitoring wells sampled, and 32 wells exceeded criteria for PFHxS, PFNA, PFOS, and PFOA. The maximum concentration of PFAS was PFOS at 6,670 ppt. Based on water level measurements collected in 2023, groundwater on the eastern portion of the site flows to the east towards the Trenton Channel and groundwater to the west, flows towards West Jefferson Avenue.

EGLE, DHHS, and local health confirmed there are no residential wells nearby; residents are connected to municipal water.
Existing groundwater monitoring wells on the site will be routinely sampled for PFAS during the Remedial Investigation.
