Drinking water in Grand Blanc, Michigan is delivered through 5 EPA-regulated community water systems serving an estimated 29,478 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 25 violation records across the 5 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 3 distinct EPA contaminant codes: LEAD AND COPPER RULE REVISIONS, Lead and Copper Rule, Arsenic.

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.
