EPA PFAS Analytic Tools 'Industry Sectors' layer (PAT_Industry_Sectors, layer 3 of the public PFAS_Analytic_Tools_Layers ArcGIS FeatureServer) -- facilities with federal CAA/CWA/RCRA permits operating in industry sectors that literature review indicates may handle or release PFAS, per EPA's ECHO methodology. This is the live feed backing the interactive PFAS Analytic Tools dashboard's Industry Sectors tab. 714 facilities as of 2026-08-12, dominated by Part 139 airports (536) plus smaller NAICS/SIC-driven categories (waste management, chemical manufacturing, printing, metal coating, etc.). Note: this live layer is significantly narrower than the ~120,000-facility figure cited in EPA's marketing description of the tab's methodology -- see the Source .md for full reconciliation.
