Volcano has no town government of its own, so Amador County runs its elections and most services, and its children attend Amador County Unified School District. Tap water in most of Volcano comes from Volcano Community Service Dist, which has a clean five-year EPA record (about 23% of systems its size had a health-based violation) and a latest lead result below detection.

Power comes from PG&E
PG&E (Pacific Gas & Electric Co.), an investor-owned utility, serves all of Volcano. Its homes paid an average of 37.5¢ per kWh in 2025, about $174 a month (its average across California, for customers on its standard service). California lets you buy power from another supplier; 66% of PG&E’s home customers do, and PG&E still delivers it.

Water comes from Volcano Community Service Dist
Volcano Community Service Dist supplies Volcano: about 83% of residents live in its service area. About 17% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws ground water influenced by surface water and serves 103 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 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.
