Does Kinneloa Irrigation Dist. have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in October 2023. The violations listed here began between March 1985 and October 2023. By type: 7 contaminant level above the legal limit, 3 monitoring, 1 reporting and 1 monitoring and reporting. The contaminant or rule involved most often is Fluoride (7 of them). EPA lists 7 as archived and 5 as resolved. 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. 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.
