Drinking water in California, Maryland is delivered through 28 EPA-regulated community water systems serving an estimated 59,957 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 0 violation records across the 28 active community systems shown here. Monitoring and reporting records are not present in the extract. No contaminant code appears in the health-based records.

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