Waste Site Cleanup Notifications and Status

MassDEP's public lookup reports where an RTN site is in the assessment and cleanup process and what has been done; the downloadable product publishes current status and linked actions, while harvested fields verify current-status date, phase, and RAO class. Report raw dated lifecycle values only; an RTN or unexplained status is not proof of open standing, completed cleanup, or adequate remediation.

MassDEP's standing public search and five-file download let a buyer screen an arbitrary Massachusetts location for RTN-keyed reported releases and retrieve address, status, primary release information, chemicals, location type, release source, and actions. Use address or site matching and preserve notification and status semantics; a reported release is not proof of present contamination.

MassDEP publicly exposes all regulated Waste Site Cleanup notifications with Release Tracking Number, address, status, and primary release information. The Source therefore identifies which officially tracked contamination or cleanup cases apply at a buyer-named parcel. Roster presence establishes a tracked notification or case, not current contamination or present case standing.

MassDEP states that its public lookup summarizes where a site is in the assessment and cleanup process and what has been done. The downloadable product includes current status plus linked action, chemical, location, and source files; the harvested primary file verifies CURRENT_ST, CURRENT_DA, PHASE, and RAO_CLASS fields keyed by RTN. Preserve raw MassDEP meanings and do not infer remedy effectiveness, liability, or current contamination.

MassDEP describes more than 40,000 reported oil or hazardous-material releases and publishes RTN-keyed primary release information with linked chemical, location-type, and release-source files. Harvested primary fields also identify notification, category or classification, and the oil-or-hazardous-material indication. This is reported-release evidence; preserve notification basis and do not infer confirmed causation, exact quantity, or response outcome where absent.
