Does Beaver Water System have drinking water violations?

By type: 7 monitoring and reporting and 5 monitoring. The contaminant or rule involved most often is Chlorine (7 of them). EPA lists 6 as archived and 6 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.
