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
Source Register of another agency · fetched 2026-10-07 · verify at EPA ECHO ↗
1 health-based violation open now. A health-based violation means a measured level went over a federal limit, or a required treatment step was not carried out — not a missed form. What that means for anyone drinking the water depends on the contaminant and the dose; read EPA's own report and the system's Consumer Confidence Report rather than anything inferred here.
EPA's own summary: violations in 0 of the last 12 quarters.

What the regulator did about it
7 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.

| 2026-07-10 | St Public Notif requested | state |

| 2020-05-13 | St Compliance achieved | state |
| 2020-05-05 | St Violation/Reminder Notice | state |

No lead or copper 90th-percentile result on the federal record for this system.
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.
