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 SDWIS record for Rockville shows 27 total violations across all 165 systems, of which 27 are health-based, meaning either a Maximum Contaminant Level (MCL) was exceeded or a required treatment technique was not followed.

For current water-quality status and treatment practices, review your local utility's most recent Consumer Confidence Report or contact the Virginia drinking water program. All records above reflect federal EPA SDWIS data and are not independently verified against state databases.

About This Data

Water system data comes from the EPA's Safe Drinking Water Information System (SDWIS). Violations are reported by state agencies to EPA and include both health-based (MCL exceedances) and monitoring/reporting violations.

A reported violation does not necessarily mean water is currently unsafe to drink. Many violations are resolved quickly, and public water systems are required to notify customers of significant issues. For current water quality, contact your local water utility.

TRI facility data comes from the EPA Toxic Release Inventory. Facilities shown are those that self-report to the TRI program. PlainEnviro presents this data without advocacy framing.
