Water comes from Davis water system
The Davis water system supplies Davis: about 94% of residents live in its service area. About 6% 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 589 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 78% of the 5,327 systems serving 501–1,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jul–Dec 2025, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 9.8 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
