What does “community water system” mean?

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 surface water means the system buys surface water from another public water system rather than drawing its own. 37 Minnesota systems (0.6%) list purchased surface water as their primary source.

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. 8 of the 8 active systems in Rock County (100%) are also owned by a local government.

Does Magnolia have drinking water violations?

EPA's records list 6 violations for this system; none is health-based, and the most recent began in July 2007. The violations listed here began between April 1993 and July 2007. By type: 6 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 5 as archived and 1 as resolved. 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. 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.
