U.S. Environmental Protection Agency

Superfund Enterprise Management System Active Site Inventory

EPA's quarterly Facility Registry Service Interests download exposes the SEMS layer as an ESRI file geodatabase containing active, non-archived Superfund sites nationwide. The integrated product emits normalized address and NAD83 coordinate columns, a SEMS indicator, and the underlying facility identity, location, NPL status, federal ownership, EPA region, and program-interest metadata. It can be consumed as a complete bulk layer or queried through the documented ArcGIS FeatureServer fallback.
