How does Blackwater Creek Ranch compare with other water systems in Park County?
By EPA's size categories, Blackwater Creek Ranch is a very small system (500 people or fewer). Park County has 49 active public water systems. Its population served is well below the county average of 777 people per system, and accounts for less than 0.1% of the 38,068 people reported by systems filed under the county. Across Wyoming, the 775 active systems average 838 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Blackwater Creek Ranch is well below 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. Wyoming has 352 active transient non-community water systems, 45% of the state's 775 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 585 Wyoming systems (75%) list groundwater as their primary source.
Who owns and regulates Blackwater Creek Ranch?
EPA lists Blackwater Creek Ranch as privately owned. The WY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 27 of the 49 active systems in Park County (55%) are also privately owned.
Does Blackwater Creek Ranch have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in August 2025. The violations listed here began between July 2004 and August 2025. By type: 6 monitoring and reporting, 3 monitoring and 3 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 10 as resolved 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. 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.
