Kapaau has no town government of its own, so Hawaii County runs its elections and most services, and its children attend Hawaii Department of Education. Tap water in most of Kapaau comes from the North Kohala water system, which has a clean five-year EPA record (about 20% of systems its size had a health-based violation) and a latest lead result below detection.

Water comes from North Kohala water system
The North Kohala water system supplies Kapaau: about 84% of residents live in its service area. About 16% 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 4,933 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 2019–Dec 2021, 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.
