Grede Landfill, located at 801 South Carpenter Avenue, Kingsford, is a three-acre Type III landfill that accepted foundry sands and associated wastes generated by Grede Foundry. The landfill quit accepting wastes in 1991 and was capped and closed in 1993. Hydrogeological investigations that started in 1985 showed groundwater impacts, including metals and other contaminates. Due to the groundwater contamination caused by the landfill, and the possibility that there were PFAS-containing wastes in the landfill, EGLE requested that Grede Landfill sample the groundwater for PFAS.
Groundwater flow is to the south/southeast, toward the Menominee River. The area downgradient from the landfill is served by municipal water. However, there are four downgradient residential drinking water wells that have been confirmed by local health department.
