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.

12 of 35 shown; the rest are on the ECHO report.
Lead and copper: the latest 90th-percentile lead result is 0.0017 mg/L (sampling period ending 2025-12-31) against an action level of 0.015 mg/L; 7 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.

EPA did not sample this system under UCMR 5 (the rule covered every system serving more than 3,300 people and a drawn sample of smaller ones).
