TapWaterMap

Query US tap-water quality from the EPA's own SDWIS records: the water systems serving a city, contaminants and violations on record (with dates and whether the EPA classifies them as health-based), compare cities, and explain contaminants. Public, no-auth, read-only — ~19,000 cities across all 50 states + DC, ~1.5M EPA records. Every response reports what the EPA recorded, never a safety verdict.
