Drinking water in Sedalia, Missouri is delivered through 9 EPA-regulated community water systems serving an estimated 22,360 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 22 violation records across the 9 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, Revised Total Coliform Rule, Stage 1 Disinfectants and Disinfection Byproducts Rule. 18 TRI-reporting industrial facilities are also located within the city limits.

All records above reflect federal EPA SDWIS data and are not independently verified against state databases.
