What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Minnesota has 987 active community water systems, 15% of the state's 6,465 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 89 Minnesota systems (1.4%) list purchased groundwater as their primary source.
Who owns and regulates Mckinley?
EPA lists Mckinley as owned by a local government. The MN state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 38 of the 356 active systems in St. Louis County (11%) are also owned by a local government.
Does Mckinley have drinking water violations?
EPA's records list 7 violations for this system; 3 are health-based, and the most recent began in January 2026. The violations listed here began between August 1992 and January 2026. By type: 4 monitoring and reporting and 3 required treatment not met. The contaminant or rule involved most often is Lead and Copper Rule (2 of them). EPA lists 4 as resolved, 2 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
