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.

Please note that this landfill is CLOSED and does not accept waste.
The DSC McLouth Steel-Gibraltar Plant Superfund site is located at 28000 West Jefferson Street, Gibraltar. The site is comprised of approximately 600 acres and has three closed landfills where the leachate control systems have been mismanaged. The landfill located on the western portion of the site, Countywide, historically accepted steel production waste from McLouth Steel Products Plant in Trenton as well as the Gibraltar plant, and later operated as a demolition debris landfill. EGLE manages the leachate at Countywide Landfill by hauling and disposing of the leachate off-site. PFAS was discovered in the leachate at Countywide Landfill in 2018.
The lead for the site, USEPA, has been completing a site-wide Remedial Investigation since 2016. Groundwater samples were analyzed for PFAS during the June 2022 sampling event and PFOA and PFOS were detected above groundwater cleanup criteria. The highest groundwater exceedance was PFOA at 41.3 ppt (compared to 8 ppt). EPA has additional investigative and groundwater sampling events planned at the site.
Groundwater flow direction at the site is still being determined. The localized groundwater flow across Countywide Landfill generally travels in a northwesterly direction.
Several water bodies are present at and near the site that have the potential to be impacted by contaminated groundwater and/or surface water runoff originating from the site. The Frank and Poet Drain and Brownstown Creek both run through the site boundary and eventually discharge into the Detroit River. There are several ponds at the site, and the largest one, called the North Pond, has an overflow pipe that discharges directly into the Frank and Poet Drain. Directly east of the site and across West Jefferson Ave lies Humbug Marsh. Beyond Humbug Marsh is the Detroit River.

The area is served municipal water from Great Lakes Water Authority. EGLE is working with MDHHS to identify any residential drinking water wells in the area and will conduct sampling if necessary.
EGLE will continue to support EPA as they complete additional sampling events at the site.
