Arapahoe has no town government of its own, so Cheyenne County runs its elections and most services, and its children attend Cheyenne County School District RE-5. Tap water in most of Arapahoe comes from the Arapahoe Wc water system, which has a clean five-year EPA record (about 22% of systems its size had a health-based violation) and a latest lead result below detection.

Water comes from Arapahoe Wc water system
The Arapahoe Wc water system supplies Arapahoe: 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 99 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 78% of the 11,392 systems serving <=100 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2023–Dec 2025, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 0.5 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
