How does Historic Pines Ranch compare with other water systems in Custer County?

By EPA's size categories, Historic Pines Ranch is a very small system (500 people or fewer). Custer County has 17 active public water systems. Its population served is well below the county average of 245 people per system, and accounts for 0.9% of the 4,164 people reported by systems filed under the county.

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. Colorado has 956 active transient non-community water systems, 43% 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 Historic Pines Ranch?

EPA lists Historic Pines 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. 8 of the 17 active systems in Custer County (47%) are also privately owned.

Does Historic Pines 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 January 2024. The violations listed here began between March 2021 and January 2024. By type: 9 monitoring and reporting, 2 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is E. coli (6 of them). EPA lists 9 as resolved, 2 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.
