Water comes from Derry Water Dept
Derry Water Dept supplies Derry: about 61% of residents live in its service area. Drew Woods serves another 9%. About 21% 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 Manchester Water Works as seller) and serves 17,370 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 2021–Dec 2023, 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.
