EPA Superfund site
FREEWAY SANITARY LANDFILL
Exposure status: insufficient data
Data limitations: Proximity to a Superfund site boundary does not mean your property is contaminated. EPA site boundaries show the area designated for cleanup, not the full extent of contamination. Groundwater plumes can extend beyond site boundaries. This tool shows publicly available EPA federal data. It is not affiliated with or endorsed by EPA, and is not a substitute for a professional environmental assessment.
About this site's exposure pathways
As of September 2026, the Freeway Sanitary Landfill Superfund site is considered “Insufficient Data to make a Human Exposure evaluation” (HEID). EPA uses this status when there is not enough evidence to determine whether human exposures are occurring above acceptable risk-based levels. State gas probe data found methane at explosive levels near the landfill. Subslab gas samples from nearby buildings did not show a vapor intrusion risk for those structures, but one on-site building has not been fully evaluated for this pathway. The Minnesota Pollution Control Agency, the lead agency, needs access to that property to complete the investigation. MPCA will complete the remaining evaluation once it obtains access. EPA currently anticipates sufficient data for a human exposure evaluation by December 2027 because access is needed before sampling can continue.
