GroundTruth

Check any US address against the public record before you rent, buy, or sign. One search runs the checks a careful buyer or renter would run: school quality, flood/fire/earthquake zones, groundwater contamination, highway noise, walkability, the internet providers and advertised speeds the FCC lists for the block, the federal environmental records near the point -- Superfund cleanup sites, factories that report toxic chemical releases (the Toxics Release Inventory, TRI), facilities the EPA currently flags for significant noncompliance -- and the drinking-water systems serving the area. Records with dates and distances, never a "safety score."

Coverage is strongest in California (deepest in the Bay Area); school scores use state test results from all 50 states and DC (2023-2025 results). Where a check has no data for your location it SAYS so -- an honest "no data" beats a made-up score. And absence of records is never a clean bill of health.

Indexed: 1840 Superfund sites, 21482 TRI facilities, 24421 flagged facilities, 49378 water systems (snapshots of 2026-10-05). Snapshots refresh monthly; EPA updates the underlying datasets on their own schedules.
