How does Sunnyfield Acres compare with other water systems in Waukesha County?

By EPA's size categories, Sunnyfield Acres is a very small system (500 people or fewer). Waukesha County has 589 active public water systems. Its population served is about half of the county average of 549 people per system, and accounts for less than 0.1% of the 323,265 people reported by systems filed under the county. Across Wisconsin, the 11,056 active systems average 469 people each. Nationally, the average active community water system reports serving 6,703 people, so Sunnyfield Acres 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. Wisconsin has 1,053 active community water systems, 9.5% 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 Sunnyfield Acres?

EPA lists Sunnyfield Acres 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. 452 of the 589 active systems in Waukesha County (77%) are also privately owned.

Does Sunnyfield Acres have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2014. The violations listed here began between June 1999 and January 2014. By type: 8 monitoring and reporting, 3 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 11 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.
