GroundTruth - Environmental Records

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). FCC data as of 2025-12-31 (release D25_13oct2026). Wired and fixed wireless service comes first; satellite service is listed last, in its own section. Where a point is in no Census block with FCC data, counts are for the surrounding H3 cell. Speeds are advertised maximums reported by providers, not measured speeds. The FCC data has no street addresses, so it cannot confirm service at one house. Input is either a street address (geocoded by the US Census geocoder) or lat/lon coordinates.

Public water systems serving a US state + county and/or city, with health-based SDWA violation summaries. Matching is approximate (service boundaries are not public); the user's water bill names their actual utility.

Environmental records within a radius of a US location, from GroundTruth's monthly snapshot of three EPA datasets: National Priorities List (Superfund) sites, facilities from the newest Toxics Release Inventory (TRI) reporting year, and active facilities with a current significant-noncompliance or high-priority-violation flag in EPA ECHO. Each record carries its distance, and provenance gives each dataset's source and snapshot date (as_of). Input is either a street address (geocoded by the US Census geocoder) or 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.

Layer scores for a US location: school quality, natural hazards, groundwater contamination, Superfund proximity, air quality, highway noise, walkability, crime, and climate pleasantness (pleasant days/year). Scores are 0-1 with 1.0 = favorable; null = cannot score that layer here. The scores are model estimates drawn from public datasets, not safety ratings. no_coverage marks a layer whose number is a placeholder outside that layer's coverage: the value means no data, not a score. When a layer's number has limits the score alone does not show (a placeholder value, a proxy, partial source data), caveats.<layer> states them. The scores are not a safety assessment, and an absence of adverse signals is not a clean bill of health. Coverage: Superfund/toxic-release proximity national; air quality, groundwater, and natural hazards a San Francisco Bay Area grid (about lat 37.0 to 38.6, lon -122.8 to -121.4, which also takes in Sacramento), with no_coverage placeholders elsewhere; highway noise Bay Area; walkability California; schools all 50 states and DC (2023-2025 results); climate CONUS (gridMET 4km, 2015-2024); Alaska, the Florida Keys, Hawaii, Puerto Rico and the US Virgin Islands (Daymet V4, 2011-2020); within 40 km of 3 NOAA weather stations in American Samoa, the Northern Mariana Islands and Guam (2016-2025); null elsewhere; crime SF/Oakland/Chicago. Input is either a street address (geocoded by the US Census geocoder) or lat/lon coordinates.
