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 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 Leota?

Does Leota have drinking water violations?
EPA's records list 7 violations for this system; 6 are health-based, and the most recent began in November 2011. The violations listed here began between July 1991 and November 2011. By type: 6 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 6 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.
