Does Mountain Haus have drinking water violations?
EPA's records list 10 violations for this system; none is health-based, and the most recent began in July 2018. The violations listed here began between October 2002 and July 2018. By type: 9 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 9 as resolved and 1 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.
