EPA's live site profile is authoritative for cleanup status and history.
This page states the federal record as of 2026-08-05. It is not a safety assessment: the NPL (National Priorities List) is the federal Superfund cleanup list, the status describes where a site is in that process, and "deleted from the NPL" means EPA determined cleanup was completed.
