Does Berthusen Road Water Association have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in June 2006. The violations listed here began between October 1979 and June 2006. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 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.
