EPA Superfund Site

BEHR DAYTON THERMAL SYSTEM VOC PLUME

OH | EPA ID OHN000510164

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 Control status at the Behr Dayton Site. This Site was identified as having vapor intrusion (VI) problems in the early 2000's, and investigations and mitigations have been ongoing since. EPA issued an interim Record of Decision in 2019 to treat the groundwater plume and conduct VI monitoring, mitigation, and maintenance. Though some 250 structures have been equipped with mitigation systems to prevent inhalation of dangerous levels of indoor air from the VI pathway, additional properties need to be sampled and O&M of the existing systems need to be continued. The activities planned to make the Human Exposure determination include a continuation of the VI monitoring, installing mitigation systems, as needed, and inspecting and maintaining existing systems.

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.
