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 Steen?

Does Steen have drinking water violations?

EPA's records list 6 violations for this system; none is health-based, and the most recent began in July 2025. The violations listed here began between July 1997 and July 2025. By type: 5 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Lead and Copper Rule (2 of them). EPA lists 5 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.
