Water comes from San Juan Water District
San Juan Water District supplies Granite Bay: about 76% of residents live in its service area. Placer Cwa - Foothill serves another 22%. About 8% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws surface water and serves 29,598 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 83% of the 3,525 systems serving 10,001–50,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2022–Dec 2024, was 0.0 ppb, below the 15 ppb action level that applied. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
