Drinking water in Rock Springs, Wyoming is delivered through 11 EPA-regulated community water systems serving an estimated 30,865 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 1 violation record across the 11 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 1 distinct EPA contaminant code: LEAD AND COPPER RULE REVISIONS. 6 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.
