Hydrohistorian
Modelled boundary. EPA estimated this service area (Random Forest) rather than tracing a utility-supplied map; treat the edge as approximate. About 17 km².

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

Compliance record

EPA's summary: violations in 2 of the last 12 quarters; not a serious violator. Contaminants in violation in the last three years, in EPA's words: 0200=Surface Water Treatment Rule; 0300=Interim Enhanced Surface Water Treatment Rule; 0999=Chlorine.
No health-based or open violation on the federal record for this system.
Lead and copper: the latest 90th-percentile lead result is 0.007 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.
