Water comes from Montara Water and Sanitary District
Montara Water and Sanitary District supplies Moss Beach: about 93% of residents live in its service area. Coastside County Water District serves another 7%. About 4% 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 6,078 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 80% of the 5,012 systems serving 3,301–10,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2024–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.
