DWR structures that name this system
Source Probable join · fetched 2026-10-06 · 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

2 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 5 of the last 12 quarters. In violation for, in EPA's words: 2456=Total Haloacetic Acids (HAA5); 2950=TTHM; 5200=LEAD AND COPPER RULE REVISIONS. Currently: 5200=LEAD AND COPPER RULE REVISIONS.

What the regulator did about it
46 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 0.0013 mg/L (sampling period ending 2026-12-31) against an action level of 0.015 mg/L, below it. 20 results on file, 1 lead result over the action level all time.
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.
