Trust and limits
Built from public federal data. Distance is not exposure.
Proximity to a Superfund site boundary does not mean your property is contaminated. EPA boundaries show the cleanup area — not the full extent of contamination. Groundwater plumes can extend beyond site boundaries. This tool is not affiliated with or endorsed by EPA.
