GroundTruth - Environmental Records

Federal environmental records within a radius of a US location: Superfund/NPL sites, TRI toxic-release facilities, and facilities currently flagged for significant noncompliance. Pass EITHER a street address (geocoded via the US Census geocoder) OR lat/lon coordinates.

{
  "type": "object",
  "properties": {
    "address": {
      "description": "US street address incl. city/state (alternative to lat/lon)",
      "type": "string"
    },
    "lat": {
      "description": "Latitude (US)",
      "type": "number"
    },
    "lon": {
      "description": "Longitude (US, negative)",
      "type": "number"
    },
    "radius_km": {
      "description": "Search radius in km (default 10, max 50)",
      "type": "number"
    }

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.

{
  "type": "object",
  "properties": {
    "city": {
      "description": "City served (optional)",
      "type": "string"
    },
    "county": {
      "description": "County name (optional)",
      "type": "string"
    },
    "state": {
      "description": "Two-letter state code, e.g. MD",
      "type": "string"
    }
  },
  "required": [
    "state"
  ]
}

Address due-diligence 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. no_coverage flags placeholder values machine-readably; relay caveats verbatim. Coverage: Superfund/toxic-release proximity national; other environmental layers CA/Bay Area; schools all 50 states and DC (2023-2025 results); climate CONUS (no AK/HI); crime SF/Oakland/Chicago. Pass EITHER a street address (geocoded via the US Census geocoder) OR lat/lon coordinates.
