By EPA's size categories, Autumn Fields is a very small system (500 people or fewer). Kewaunee County has 72 active public water systems.

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.
Who owns and regulates Autumn Fields?
EPA lists Autumn Fields 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. 60 of the 72 active systems in Kewaunee County (83%) are also privately owned.
Does Autumn Fields have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in June 2011. The violations listed here began between October 2004 and June 2011. By type: 6 contaminant level above the legal limit, 4 public notice, recordkeeping or other and 2 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 9 as resolved and 3 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.
