Water comes from Exeter Water Department

About 10% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws surface water and serves 12,236 people in all.
1 health-based violation reported to EPA in the five years to October 2026: disinfection byproducts (TTHM), beginning Oct 2025. 83% of the 3,525 systems serving 10,001–50,000 people had none.
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.
