How does Dp Properties compare with other water systems in Ozaukee County?

By EPA's size categories, Dp Properties is a very small system (500 people or fewer). Ozaukee County has 249 active public water systems. Its population served is well below the county average of 371 people per system, and accounts for less than 0.1% of the 92,392 people reported by systems filed under the county. Across Wisconsin, the 11,056 active systems average 469 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Dp Properties is about half of that figure.

What does “transient non-community water system” mean?

A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Wisconsin has 9,112 active transient non-community water systems, 82% 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 Dp Properties?

EPA lists Dp Properties 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. 218 of the 249 active systems in Ozaukee County (88%) are also privately owned.

Does Dp Properties have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2004. The violations listed here began between January 1996 and October 2004. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (4 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.
