Drinking water in Wilson, Wyoming is delivered through 20 EPA-regulated community water systems serving an estimated 5,278 people. Each system is tracked in the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act, which requires testing for regulated contaminants, consumer notification of violations, and publication of an annual Consumer Confidence Report.
PlainEnviro's health-based SDWIS extract shows 10 violation records across the 20 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 3 distinct EPA contaminant codes: Groundwater Rule, Lead and Copper Rule, Surface Water Treatment Rule.
A past EPA health-based registry row does not describe water delivered today or current compliance status; utilities notify customers and remediate under state primacy oversight when required. For current water-quality status and treatment practices, review your local utility's most recent Consumer Confidence Report or contact the Wyoming drinking water program. All records above reflect federal EPA SDWIS data and are not independently verified against state databases.
