Water comes from Missouri West Water System
Missouri West Water System supplies Mandan: about 52% of residents live in its service area. About 48% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It buys treated surface water (EPA lists Omnd Water Treatment Plant and City of Mandan as sellers) and serves 4,303 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 2022–Dec 2024, 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.
