Does Moriah Wd have drinking water violations?

Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in January 2021. The violations listed here began between May 1988 and January 2021. By type: 7 contaminant level above the legal limit, 3 required treatment not met and 2 monitoring and reporting. The contaminant or rule involved most often is Haloacetic acids (HAA5) (5 of them). EPA lists 10 as resolved, 1 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
