How does Wilkinson Pioneer Park compare with other water systems in Cerro Gordo County?
By EPA's size categories, Wilkinson Pioneer Park is a very small system (500 people or fewer). Cerro Gordo County has 34 active public water systems.

Across Iowa, the 1,828 active systems average 1,718 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Wilkinson Pioneer Park is well below that figure.
What does “transient non-community water system” mean?

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,502 Iowa systems (82%) list groundwater as their primary source.
Who owns and regulates Wilkinson Pioneer Park?

The IA 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 34 active systems in Cerro Gordo County (32%) are also owned by a local government.
Does Wilkinson Pioneer Park have drinking water violations?
EPA's records list 8 violations for this system; 5 are health-based, and the most recent began in July 2013. The violations listed here began between July 1985 and July 2013. By type: 5 contaminant level above the legal limit and 3 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 7 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.
