How does Town of Genoa compare with other water systems in Lincoln County?
By EPA's size categories, Town of Genoa is a very small system (500 people or fewer). Lincoln County has 6 active public water systems, and Town of Genoa is the 5th-largest of them by population served. Its population served is well below the county average of 1,288 people per system, and accounts for 2% of the 7,725 people reported by systems filed under the county. Across Colorado, the 2,207 active systems average 3,400 people each. Nationally, the average active community water system reports serving 6,703 people, so Town of Genoa is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Colorado has 1,068 active community water systems, 48% 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 Town of Genoa?
EPA lists Town of Genoa as owned by a local government. 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. 4 of the 6 active systems in Lincoln County (67%) are also owned by a local government.
Does Town of Genoa have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between February 2025 and January 2026. By type: 7 monitoring and reporting, 2 public notice, recordkeeping or other, 1 reporting, 1 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (2 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.
