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 May 2026, the N.W. Mauthe Superfund site is considered “Insufficient Data to make a Human Exposure evaluation" (HEID). EPA uses this Human Exposure status when there is insufficient data/evidence to determine whether actual or reasonably anticipated human exposures are occurring, and/or whether those exposures are above acceptable risk-based levels. The planned activities to collect sufficient information to make a human exposure evaluation are to conduct surficial soil sampling at select residential properties to evaluate the potential for unacceptable risk from direct contact with soil contaminated with hexavalent chromium. EPA currently anticipates that there will be sufficient data to make a Human Exposure determination by May 2029. This does not necessarily mean that unacceptable exposures are occurring. Out of an abundance of caution, if you live near this site, please make sure to wash hands after being in contact with soils.
