Sanico North Landfill is a 17.5-acre site located at 17171 144th Avenue in Nunica, Ottawa County, and operated from the mid-1960s until the mid-1980s. The site operated as a landfill from the mid-1960s until the mid-1980s and accepted residential, commercial, agricultural and industrial waste.
On August 29, 2025, EGLE received a Baseline Environmental Assessment (BEA) for this property, which included groundwater data as high as 120 ppt PFOA (compared to 8 ppt) and 26 ppt PFOS (compared to 16 ppt). Other PFAS compounds were also detected. A BEA is a document that allows a person to buy or operate at a site without being held liable for existing contamination. Groundwater flows to the west-northwest towards Lloyds Bayou, approximately 900 feet away.
