Modelled boundary. EPA estimated this service area (Random Forest) rather than tracing a utility-supplied map; treat the edge as approximate. About 1 km².
Where the water comes from

| CASS WELL | Well | Groundwater |
| WATER FROM MCCLAVE CO0106500 | Consecutive connection (purchased) | Groundwater · from MCCLAVE WA INC |
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 10 of the last 12 quarters. In violation for, in EPA's words: 4010=Combined Radium (-226 and -228); 5000=Lead and Copper Rule. Currently: 4010=Combined Radium (-226 and -228); 5000=Lead and Copper Rule.

What the regulator did about it
84 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 0.01 mg/L (sampling period ending 2026-06-30) against an action level of 0.015 mg/L, below it. 19 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.
