What status means
Final NPL means a site is on EPA's National Priorities List. Proposed means EPA has proposed listing. Deleted means EPA removed the site from the Final NPL. These are program statuses, not comparable hazard scores or property-safety findings.
How to read this
Fact: names, status, locations and identifiers come from EPA SEMS. Limit: each point is a source reference coordinate, not a contamination boundary. The map does not determine exposure, cleanup completion, liability, health risk or safety. Use the EPA ID in the official SEMS search for current site details.
