EPA Superfund Site

BELOIT CORP.

IL | EPA ID ILD021440375

Exposure status: insufficient data

About this site’s exposure pathways: As of August 2025, there is not sufficient information available to determine the site-wide Human Exposure status at the Beloit Corp Superfund Site because of a newly identified exposure pathway. Following a fire at the Chemtool facility where aqueous fire-fighting foam was used to extinguish the fire, PFAS was added as an analyte in routine groundwater monitoring samples, including private residential wells. A new exposure pathway was discovered, as PFAS was found in private residential drinking water wells. The activities planned to make the human exposure determination include identifying the source or sources of PFAS contamination and take appropriate action to prevent continued residential exposure to PFAS above risk screening criteria. Residents have been made aware of the impacts to their wells and were offered connections to the public water supply. Work for those connections will take place in 2025 and 2026.

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.
