How does Roundup River Ranch compare with other water systems in Eagle County?

By EPA's size categories, Roundup River Ranch is a very small system (500 people or fewer). Eagle County has 46 active public water systems. Its population served is well below the county average of 2,242 people per system, and accounts for 0.2% of the 103,152 people reported by systems filed under the county. Across Colorado, the 2,207 active systems average 3,400 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Roundup River Ranch is about 61% below that figure.

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

A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Colorado has 183 active non-transient non-community water systems, 8.3% of the state's 2,207 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 166 Colorado systems (7.5%) list groundwater under influence of surface water as their primary source.

Who owns and regulates Roundup River Ranch?

EPA lists Roundup River Ranch as privately owned. The CO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 28 of the 46 active systems in Eagle County (61%) are also privately owned.

Does Roundup River Ranch have drinking water violations?

Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in March 2025. The violations listed here began between July 2018 and March 2025. By type: 8 monitoring and reporting, 2 required treatment not met and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is E. coli (5 of them). EPA lists 7 as resolved, 4 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
