These are EPA's facility records, not DWR structures. Which decreed rights sit behind an intake is the next phase; nothing here is inferred.
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

1 violation 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. In violation for, in EPA's words: 7500=Public Notice. Currently: 7500=Public Notice.
What happened
All 84 violation records on file, grouped into the 3 distinct things EPA's codes describe. Dates are the compliance period the violation is filed against.

What the regulator did about it
259 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.
| Date | Action | By |
|---|---|---|
| 2020-02-12 | St Violation/Reminder Notice | state |
| 2018-10-09 | St Compliance achieved Following installation of blending plant, system collected monthly nitrate samples at 001T, 012T, and 016 (only remaining entry points) from 2Q2018 through 3Q2018. Results ranged from 3.8 - 4.7 mg/L (001T), 5.6 - 8.5 mg/L (012T), and 6.1 - 8.2 mg/L (016). System therefore went 2 quarters without MCL violation, so per TRIC, all nitrate MCL violations can be SOX'd TIK 10/9/2018 |

Lead and copper
The latest 90th-percentile lead result is 0.0 mg/L (sampling period ending 2026-06-30) against an action level of 0.015 mg/L, below it. 19 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, 2024-05-15 to 2024-11-05. No PFAS was detected at the reporting limits; lithium was measured up to 28.0 µg/L (no federal limit).
| 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 | 4 | 28.0 | 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 ↗.
