Water comes from Greenwich Village water system
The Greenwich Village water system supplies Greenwich: about 92% of residents live in its service area. About 8% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws ground water influenced by surface water and serves 1,665 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 2021–Dec 2023, was 3.0 ppb, below the 15 ppb action level that applied. That’s higher than 82% of similar systems’ latest results.
