EPA Superfund Site

SOUTHEAST HENNEPIN AREA GROUNDWATER AND VAPOR

MN | EPA ID MNN000506043

Human exposure is NOT currently under control

About this site’s exposure pathways: As of August 2025, the Southeast Hennepin Area Groundwater and Vapor Superfund Site is considered “Current Human Exposure Not Under Control” because of potential vapor intrusion risk to humans in residences and businesses. The Minnesota Pollution Control Agency is conducting sampling to identify properties with elevated subsurface vapor intrusion exposure potential. Elevated vapor intrusion levels associated with volatile organic compounds, primarily trichloroethylene, that could potentially pose risk human to human health has been identified at residences and businesses, which are being addressed by the installation of vapor mitigation systems as they are identified. Additional residences and businesses remain to be evaluated. The planned activities to address this include sampling remaining residences and businesses and installing vapor mitigation systems where needed. In addition, a Remedial Investigation began in May 2025.

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.
