Water comes from Cambria water system
The Cambria water system supplies Cambria: about 61% of residents live in its service area. The Orchards Mhc serves another 36%. About 3% 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 Rend Lake Inter-City Water System and Carterville as sellers) and serves 1,727 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 78% of the 7,966 systems serving 1,001–3,300 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. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
