EPA Superfund site
GENERAL MILLS/HENKEL CORP.
Human exposure is NOT currently under control
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 June 2026, the General Mills/Henkel Corp. site is considered "Current Human Exposures Not Under Control" (HENC) due to trichloroethylene (TCE) contamination in groundwater posing a vapor intrusion risk to nearby residences and businesses. The Minnesota Pollution Control Agency (MPCA) transferred the site to EPA oversight on October 25, 2022. Previously, General Mills installed vapor mitigation systems in nearly 160 homes under MPCA direction and has since ceased work, attributing remaining TCE to the nearby Southeast Hennepin Area Groundwater and Vapor Superfund site. EPA began Remedial Investigation at Southeast Hennepin in May 2025 and will utilize that data to address data gaps at the General Mills/Henkel Corp. Site. MPCA has continued their vapor intrusion/soil gas investigation at the General Mills/Henkel Corp. site and the EPA expects to address the remaining VI risks at the Site with the MPCA by December 2027.
