Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,261 Minnesota systems (97%) list groundwater as their primary source.
Who owns and regulates Barnum?

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. 11 of the 75 active systems in Carlton County (15%) are also owned by a local government.
Does Barnum have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2022. The violations listed here began between April 2000 and October 2022. By type: 11 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Lead and Copper Rule (2 of them). EPA lists 10 as resolved and 2 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.
