Superfund Alternative Approach indicator
Whether a site is managed under EPA’s Superfund Alternative Approach.
Sources that carry it
2 sourcesEPA's PFAS Analytic Tools Superfund layer identifies National Priorities List sites with reported PFAS detections. The integrated product filters the ArcGIS layer to NPL_Site=Yes and emits 464 site records with EPA identifiers, names, addresses, coordinates, NPL status, site type, program context, and profile links. It preserves the 18 fetched ArcGIS attributes and adds seven normalized location and PFAS indicator columns.
EPA's SEMS Archived Site Inventory identifies former CERCLIS-NFRAP sites removed from active Superfund tracking where no further federal remedial action is planned unless new information changes that determination. The integrated Envirofacts API product emits nationwide site identifiers, names, address and jurisdiction fields, limited coordinates, NPL and non-NPL status, federal-facility and Superfund Alternative Approach indicators, archive dates, standardized address columns, and a SEMS_ARCHIVE flag.
