Drinking water in East Helena, Montana is delivered through 18 EPA-regulated community water systems serving an estimated 6,797 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.

The records carry 3 distinct EPA contaminant codes: Revised Total Coliform Rule, Lead and Copper Rule, Arsenic. 1 TRI-reporting industrial facility is also located within the city limits.
