How does Monroes Monderosa compare with other water systems in Yukon-Koyukuk Census Area County?

Alaska has 689 active transient non-community water systems, 52% of the state's 1,322 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,054 Alaska systems (80%) list groundwater as their primary source.

Does Monroes Monderosa have drinking water violations?
EPA's records list 10 violations for this system; 3 are health-based, and the most recent began in June 2024. The violations listed here began between June 1986 and June 2024. By type: 6 monitoring and reporting, 3 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (4 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.
