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 ↗
No open violation and no health-based violation on EPA's federal record for this system at the last monthly fetch. That is a record of reported compliance, not a test result: SDWIS carries violations, not routine sample values.
EPA's own summary: violations in 0 of the last 12 quarters.
No health-based or open violation on the federal record for this system.
What the regulator did about it
31 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 0.0051 mg/L (sampling period ending 2025-12-31) against an action level of 0.015 mg/L, below it. 10 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.
PFAS and lithium: EPA's UCMR 5 monitoring, 2023–2025
Source Register of another agency · fetched 2026-10-09 · verify at EPA UCMR occurrence data ↗
5 samples, 120 results, 2024-01-29 to 2024-11-04. No PFAS was detected at the reporting limits; lithium was not detected.
| Contaminant | Results | Detected | Highest, µg/L | Reporting limit |
|---|---|---|---|---|
| HFPO-DA | 4 | 0 | < 0.005 | 0.005 |
| PFHxS | 4 | 0 | < 0.003 | 0.003 |
| PFNA | 4 | 0 | < 0.004 | 0.004 |
| PFOA | 4 | 0 | < 0.004 | 0.004 |
| PFOS | 4 | 0 | < 0.004 | 0.004 |
| lithium | 4 | 0 | < 9.0 | 9.0 |
Rows shown: every detected contaminant plus the regulated PFAS and lithium; the rest were below their reporting limits. These are UCMR monitoring samples, not compliance samples. EPA's April 2024 rule set 4.0 ng/L (0.004 µg/L) for PFOA and PFOS, the same as UCMR 5's reporting limit, so any detection of either is at or above it; the rule's compliance date and its other limits have been under revision since 2025 and are not applied here. State PFAS sampling is on CDPHE's pages ↗.
