Drinking water in Plano, Texas is delivered through 3 EPA-regulated community water systems serving an estimated 292,200 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 28 violation records across the 3 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 1 distinct EPA contaminant code: Groundwater Rule. 3 TRI-reporting industrial facilities are also located within the city limits.
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 Texas drinking water program. All records above reflect federal EPA SDWIS data and are not independently verified against state databases.
