How does Blue Leaf School LLC compare with other water systems in Boulder County?

By EPA's size categories, Blue Leaf School LLC is a very small system (500 people or fewer). Boulder County has 81 active public water systems. Its population served is well below the county average of 5,397 people per system, and accounts for less than 0.1% of the 437,116 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 Blue Leaf School LLC is well 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 Blue Leaf School LLC?

EPA lists Blue Leaf School LLC 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. 53 of the 81 active systems in Boulder County (65%) are also privately owned.

Does Blue Leaf School LLC have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in April 2026. The violations listed here began between August 2025 and April 2026. By type: 9 monitoring and reporting, 2 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (9 of them). EPA lists 9 as resolved and 3 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.
