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 Seaforth?

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. 15 of the 30 active systems in Redwood County (50%) are also owned by a local government.
Does Seaforth have drinking water violations?
EPA's records list 10 violations for this system; none is health-based, and the most recent began in October 2024. The violations listed here began between January 2012 and October 2024. By type: 9 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Chlorine (6 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.
