DWR structures that name this system
Source Probable join · fetched 2026-09-09 · matched on DWR's recorded contact or an EPA intake name; verify on the dossier
No DWR structure on file records this system as its contact, and none of its EPA intakes matches a structure name in its districts. DWR records a contact on only a fraction of structures, and only for districts fetched from its live service, so this is absence of a record, not evidence of no rights.
Compliance record
Source Register of another agency · fetched 2026-09-09 · verify at EPA ECHO ↗
3 violations open now, none health-based. These are monitoring, reporting or notice requirements — a sample not taken, or a result not filed on time. They are real obligations, but they are not a finding about the water itself.
EPA's own summary: violations in 12 of the last 12 quarters, significant non-compliance in 1. In violation for, in EPA's words: 2456=Total Haloacetic Acids (HAA5); 2950=TTHM; 5000=Lead and Copper Rule; 7000=Consumer Confidence Rule; 7500=Public Notice. Currently: 5000=Lead and Copper Rule; 7000=Consumer Confidence Rule; 7500=Public Notice.

What the regulator did about it
79 enforcement actions on this system's federal record. In Colorado the state is the primacy agency, so most actions are the state's; EPA acts directly on tribal systems and when it steps in.

Lead and copper
The latest 90th-percentile lead result is 0.0003 mg/L (sampling period ending 2024-12-31) against an action level of 0.015 mg/L, below it. Copper 2.25 mg/L against 1.3 mg/L, above it. 16 results on file.
The action level is not a health limit: it is the level at which the rule requires a system to act (corrosion control, public education, and in some cases replacing lead service lines). Lead mostly enters water from household plumbing, so a system-wide percentile does not tell you what comes out of one tap.
Violation, enforcement and lead/copper records are EPA SDWIS federal reporting, fetched monthly; the summary is EPA ECHO. Code names come from EPA's own REF_CODE_VALUE table. SDWIS carries violations, not routine sample results — nitrate, disinfection by-product and PFAS values are not in it, and a clean record here means nothing was reported as a violation, not that nothing was ever detected. For what was measured, ask the system for its Consumer Confidence Report.
