EPA Superfund site
NEASE CHEMICAL
Human exposure is under control, protective remedies in place
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 2025, the Nease Chemical Superfund Site is “Insufficient Data to Determine Human Health Exposure Under Control” because of a newly identified exposure pathway (i.e., vapor intrusion). Vapor intrusion data has been collected from an on-property building to determine if vinyl chloride concentrations in groundwater are impacting indoor air quality. This building was not found to be
impacted by vapor intrusion but has been recently sampled to complete the determination. The U.S. Environmental Protection Agency is currently evaluating vapor intrusion results to determine if additional sampling is warranted. Sufficient data to make a determination is expected by the end of March 2027.
