Does Rainbow Energy Center have drinking water violations?

EPA's records list 9 violations for this system; all are health-based, and the most recent began in July 2013. The violations listed here began between July 1987 and July 2013. By type: 5 required treatment not met and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Long Term 2 Enhanced Surface Water Treatment Rule (2 of them). EPA lists 7 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.
