Water comes from Chatham water system
The Chatham water system supplies Chatham: about 95% of residents live in its service area. About 4% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It buys treated ground water (EPA lists South Sangamon Water Commission and Springfield as sellers) and serves 16,423 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 83% of the 3,525 systems serving 10,001–50,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2025–Dec 2027, 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.
