Drinking water in Boise, Idaho is delivered through 41 EPA-regulated community water systems serving an estimated 285,978 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 SDWIS record for Boise shows 92 total violations across all 41 systems, of which 92 are health-based, meaning either a Maximum Contaminant Level (MCL) was exceeded or a required treatment technique was not followed. Contaminants cited in health-based violations include 8000, 4006, 5200, 0700, 5000 and 5 others. 10 TRI-reporting industrial facilities are also located within the city limits.
A past EPA violation does not mean the water is currently unsafe, utilities are required to notify customers and remediate under state primacy oversight. For current water-quality status and treatment practices, review your local utility's most recent Consumer Confidence Report or contact the Idaho 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.
