How does Whiskeys compare with other water systems in Rock County?
By EPA's size categories, Whiskeys is a very small system (500 people or fewer). Rock County has 156 active public water systems.

Nationally, the average active transient non-community water system reports serving 144 people, so Whiskeys is well below that figure.

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 Whiskeys?

Does Whiskeys have drinking water violations?
EPA's records list 3 violations for this system; 2 are health-based, and the most recent began in January 2013. The violations listed here began between January 1996 and January 2013. By type: 2 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Nitrate (2 of them). EPA lists 2 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.
