Where the water comes from

| CRUMP NO 2 | Well | Groundwater |
| CRUMP NO 3 | Well | Groundwater |
| MAURICIO WELL | Well | Groundwater |
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 2026-09-09 · 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 2026-09-09 · 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 12 of the last 12 quarters. In violation for, in EPA's words: 0700=Groundwater Rule; 0999=Chlorine; 8000=Revised Total Coliform Rule. Currently: 0700=Groundwater Rule.

What the regulator did about it
37 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 0.002 mg/L (sampling period ending 2025-06-30) against an action level of 0.015 mg/L, below it. 13 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.
