Water comes from City of Cedar Hill water system
The City of Cedar Hill water system supplies Cedar Hill: about 89% of residents live in its service area. About 9% 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 Dallas Water Utility as seller) and serves 50,904 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 90% of the 597 systems serving 50,001–100,000 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 0.4 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
The system’s full record: EPA ECHO report
EPA SDWIS via Envirofacts (violations pulled Oct 9, 2026) and ECHO (lead samples, 2026Q3); service area: EPA Community Water System Service Area Boundaries v3.0. Violations are counted by the start of their compliance period. TX0570036.
