EPA Superfund site
BELOIT CORP.
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 Beloit Corp. Superfund site is considered “Insufficient Data to make a Human Exposure evaluation” (HEID) because of a newly identified exposure pathway. The site was previously HEUC. After a fire at the Chemtool facility, PFAS was detected in private wells. Activities planned to make the human exposure determination include identifying whether the Beloit site is a source of PFAS that is presenting a potential risk to receptors and, if so, taking appropriate action to prevent continued residential exposure to PFAS above risk screening criteria. Lubrizol is revising the Site Investigation Report based on agency comments, and it is expected that additional background soil and groundwater sampling is needed so that Chemtool fire-related PFAS can be differentiated from site-specific PFAS. Sufficient data will be available to make an exposure determination in November 2028 as this provides time for additional sampling and data analysis to take place.
