How to read a result
Every system gets one of three statuses, plus a health flag when it applies
No violations reported to EPA in the past three years.
At least one violation on record. Many are monitoring or reporting lapses rather than contamination; the system page lists which rules were involved.
EPA's designation for systems with unresolved serious, multiple, or continuing violations, also called an enforcement priority.
At least one open health-based violation: a maximum contaminant level, residual disinfectant level, or treatment technique. Monitoring and reporting lapses do not raise this flag.
What this site shows
Compliance records for every public water system in the EPA Safe Drinking Water Information System: violations in the past three years, which rules and contaminants were involved, serious-violator and health-flag designations, population served, water source, and a link to the EPA facility report.
What it does not show
Measured contaminant levels, private wells, or the exact utility for a single address. Results are matched to your county; the largest community water system in a county is usually the city or town utility. For your own tap, see your utility's annual Consumer Confidence Report.
