How does Windmill Ridge Campground compare with other water systems in Washington County?
By EPA's size categories, Windmill Ridge Campground is a very small system (500 people or fewer). Washington County has 24 active public water systems. Its population served is well below the county average of 670 people per system, and accounts for 0.2% of the 16,082 people reported by systems filed under the county.

Iowa has 626 active transient non-community water systems, 34% of the state's 1,828 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,502 Iowa systems (82%) list groundwater as their primary source.
Who owns and regulates Windmill Ridge Campground?

Does Windmill Ridge Campground have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in September 2025. The violations listed here began between October 2021 and September 2025. By type: 5 monitoring and reporting, 3 public notice, recordkeeping or other, 3 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 8 as resolved, 2 as unaddressed and 2 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
