A Superfund distance runs to the nearer of the area EPA maps for the site (distance_to: epa_site_boundary, 0 with inside_site_boundary true inside it) and the one point EPA lists for the site (distance_to: epa_listed_point); each record gives both. Where EPA maps no area, a site that stretches out (a canal, a river, an underground plume) can reach closer than its point.

List FCC broadband availability for a location — Fixed broadband availability for a US location from the FCC Broadband Data Collection (BDC), counted per 2020 Census block: each provider and technology the FCC data lists in the block, with advertised maximum download and upload tiers in Mbps and how many of the block's locations each covers (residential and business-only counts). Each result's source.as_of gives the FCC data date. Wired and fixed wireless service comes first; satellite service is listed last, in its own section.

Each record carries its date, distance, and source, and provenance gives each dataset's snapshot date (as_of). Input is either a street address (geocodedviaby the US Census geocoder)ORor lat/lon coordinates. Results are records, not a safety assessment. An empty list means the snapshot holds no such record within the radius. EPA holds other records this tool does not search (Superfund sites not on the NPL, earlier TRI years, facilities without a current noncompliance flag), and an empty result does not mean the area is free of contamination.
