Drinking water in Hollister, Missouri is delivered through 12 EPA-regulated community water systems serving an estimated 5,726 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 7 violation records across the 12 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 3 distinct EPA contaminant codes: Revised Total Coliform Rule, Groundwater Rule, Coliform (TCR). 1 TRI-reporting industrial facility is 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 Missouri drinking water program. All records above reflect federal EPA SDWIS data and are not independently verified against state databases.

Many records are later resolved, and public water systems notify customers when required. For current conditions, contact your local water utility or the state drinking water program.
