Water comes from Yosemite Spring Park Util Co
Yosemite Spring Park Util Co supplies Yosemite Lakes: about 96% of residents live in its service area. About 4% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws ground water and serves 5,300 people in all.
5 health-based violations reported to EPA in the five years to October 2026: fluoride ×4, a lead and copper treatment requirement (Lead and Copper Rule Revisions), the latest beginning Oct 2024. 80% of the 5,012 systems serving 3,301–10,000 people had none. 1 older violation is still open, since 2024: a lead and copper treatment requirement (Lead and Copper Rule Revisions), per EPA’s records.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2026–Dec 2028, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 8.4 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
