How does Buhl compare with other water systems in St. Louis County?
By EPA's size categories, Buhl is a small system (501 to 3,300 people). St. Louis County has 356 active public water systems. Its population served is about twice the county average of 505 people per system, and accounts for 0.6% of the 179,795 people reported by systems filed under the county.

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. 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 Buhl?
EPA lists Buhl 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 Buhl have drinking water violations?
EPA's records list 5 violations for this system; 2 are health-based, and the most recent began in July 2025. The violations listed here began between June 1992 and July 2025. By type: 2 monitoring and reporting, 2 contaminant level above the legal limit and 1 reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 4 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.
