How does Eau Claire Energy Cooperative compare with other water systems in Eau Claire County?

What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Wisconsin has 891 active non-transient non-community water systems, 8.1% of the state's 11,056 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 10,978 Wisconsin systems (99%) list groundwater as their primary source.

EPA lists Eau Claire Energy Cooperative as privately owned. The WI state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 90 of the 111 active systems in Eau Claire County (81%) are also privately owned.
Does Eau Claire Energy Cooperative have drinking water violations?
EPA's records list 10 violations for this system; 1 is health-based, and the most recent began in June 2022. The violations listed here began between July 1995 and June 2022.
