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.
