4 structures on DWR's record 4 match an EPA intake by name. A match says who DWR lists, not who owns the water: a ditch company can own the headgate while the system owns shares, and a consultant can be the contact. The dossier holds the decree.

Compliance record
Source Register of another agency · fetched 2026-09-09 · 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
1 enforcement action 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.
| Date | Action | By |
|---|---|---|

Lead and copper
The latest 90th-percentile lead result is 0.002 mg/L (sampling period ending 2025-12-31) against an action level of 0.015 mg/L, below it. 14 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

4 samples, 120 results, 2024-03-12 to 2024-12-03. 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 ↗.
