Why this may matter, and what to check
A source is not an exposure measurement. Health effects depend on the chemical or physical agent, whether it reaches a person, its concentration, exposure route, duration and individual susceptibility.
Why this may matter
An NPL listing means EPA documented hazardous-substance contamination serious enough for a federally led investigation and cleanup. The contaminants, the media affected (soil, groundwater, indoor air, surface water) and the cleanup stage differ from site to site. A deleted site has completed its cleanup goals but can still carry use restrictions and monitoring.
How it could reach a home
Groundwater plumes can extend beyond the site boundary and do not follow the surface. Vapor intrusion, contaminated soil and surface water are assessed separately in the site record. The map pin is a site point, not the plume boundary.
What remains unknown
- Whether a plume or restriction reaches the parcel
- Current cleanup stage and remaining contamination
- Institutional controls recorded on nearby properties
What to check next
- EPA site manager / community involvement coordinator — Request the current site status, the operable-unit boundaries, plume maps and any five-year review findings.
- Environmental regulator — Ask whether nearby private wells or indoor air have been sampled and what the results were.
- Title professional — Check for recorded activity and use limitations or easements tied to the cleanup.
