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 August 2026, the Amcast Industrial Corporation Superfund site is considered “Current Human Exposure Not Under Control” (HENC) because PCB-contaminated soil in residential yards and pond sediments pose an exposure risk. PCB concentrations in residential soil are above EPA’s risk-based cleanup level of 0.22 parts per million. EPA finalized a Record of Decision on September 23, 2023, requiring cleanup of the residential yards and ponds. EPA expects to complete remedial design in September 2026, begin cleanup in April 2027, and finish by December 2028, when human exposure is expected to be under control. EPA will also clean up former industrial parcels, but they do not currently pose a residential exposure risk. EPA contacted nearby residents, sampled yard soil, and went door to door to share the results. Community outreach has included public information repositories, a website, interviews, meetings, and mailings.
