Water comes from Crescent Valley Water System
Crescent Valley Water System supplies Crescent Valley: about 85% of residents live in its service area. About 15% 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 340 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 77% of the 15,074 systems serving 101–500 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2018–Dec 2026, 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.
