Water systems
Every public water system with a published record in WaterQualityLens. Each entry links to the contaminants that utility reported to the EPA Safe Drinking Water Information System, shown with full provenance — sample date, testing agency, unit, and the legal maximum contaminant level.
Coverage is expanding. If your utility is not listed yet, a lookup by address can still resolve your system from the federal registry.

What this directory does not cover
Utility data is aggregated at the water-system level and cannot account for plumbing-specific contamination such as legacy household lead service lines. A point-of-use lab test is the only way to verify contamination introduced by your home's plumbing.
