Does Rimrock Service Area have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2016. The violations listed here began between April 2008 and July 2016. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Nitrate (2 of them). EPA lists 10 as resolved and 2 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. 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.
