Drinking water in St George, Utah is delivered through 10 EPA-regulated community water systems serving an estimated 3,151 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 24 violation records across the 10 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 2 distinct EPA contaminant codes: Groundwater Rule, Revised Total Coliform Rule.
