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 September 2026, the Eagle Zinc Co Div T L Diamond Superfund site is considered “Current Human Exposure Not Under Control” (HENC). Lead concentrations in residential soil at multiple properties exceed EPA’s risk-based regional screening level (200 parts per million) for lead in residential soils, so EPA considers this exposure pathway unacceptable. EPA will conduct soil sampling to develop an updated cleanup level for lead in residential soil and identify properties requiring remediation. Human exposure can occur through ingestion of contaminated soil and dust at affected properties. The Remedial Project Manager (RPM) will collaborate with the Community Involvement Coordinator (CIC) to communicate ways to reduce exposure risk, such as avoiding bare soil and washing hands after outside activities. Contact the RPM and CIC for more details. Human exposures are expected to be under control by June 2032, when remedial action has been completed for the necessary residential properties.
