Does Veolia Water Idaho have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2019. The violations listed here began between January 2014 and August 2019. By type: 12 monitoring and reporting. The contaminant or rule involved most often is E. coli (2 of them). EPA lists 10 as archived and 2 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.
