Safe Drinking Water Information System (SDWIS) — Violations & Enforcement records
Federally reported Safe Drinking Water Act violations and their enforcement actions (SDWA_VIOLATIONS_ENFORCEMENT.csv, EPA SDWA 2026Q2 download). PurityMap uses the health-based violations (MCL, MRDL and treatment technique) whose non-compliance began in the 10 years before July 9, 2026 for each system's track record. A violation record describes a compliance period at the water system; it is not a measurement of the water at any household tap today.
