Modelled boundary. EPA estimated this service area (Random Forest) rather than tracing a utility-supplied map; treat the edge as approximate. About 2 km².
Where the water comes from
| Facility | Kind | Water |
|---|---|---|
| DOVE CREEK CANAL | Intake | Surface water |
| WELL NO 2 | Well | Groundwater under the influence of surface water |
| WELL NO 1 | Well | Groundwater under the influence of surface water |
These are EPA's facility records, not DWR structures. Which decreed rights sit behind an intake is the next phase; nothing here is inferred.

1 structure on DWR's record 1 matches 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.

Lead and copper: the latest 90th-percentile lead result is 0.0006 mg/L (sampling period ending 2025-12-31) against an action level of 0.015 mg/L; 6 results on file.
SDWIS federal reporting carries violations and lead/copper percentiles only; nitrate, disinfection by-product and PFAS sample results are not in it. Codes are EPA's (violation, contaminant, rule); the ECHO report expands them.
