How does Garden Valley Chevron compare with other water systems in Boise County?

Does Garden Valley Chevron have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in January 2022. The violations listed here began between July 2009 and January 2022. By type: 4 public notice, recordkeeping or other, 3 required treatment not met, 2 monitoring, 2 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Groundwater Rule (4 of them). EPA lists 5 as resolved, 4 as unaddressed and 3 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
