How does Iona compare with other water systems in Murray County?
By EPA's size categories, Iona is a very small system (500 people or fewer). Murray County has 27 active public water systems. Its population served is about 21% below the county average of 206 people per system, and accounts for 2.9% of the 5,571 people reported by systems filed under the county. Across Minnesota, the 6,465 active systems average 820 people each. Nationally, the average active community water system reports serving 6,703 people, so Iona is well below that figure.
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 Iona?
EPA lists Iona 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. 11 of the 27 active systems in Murray County (41%) are also owned by a local government.
Does Iona have drinking water violations?
EPA's records list 5 violations for this system; 1 is health-based, and the most recent began in October 2014. The violations listed here began between October 1999 and October 2014. By type: 3 monitoring and reporting, 1 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 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.
