Water comes from Aquarion Water
Aquarion Water supplies Sandy Hook: about 15% of residents live in its service area. About 85% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws surface water (EPA lists Norwalk First Taxing District and Aquarion-Ridgefield and Aquarion-Stamford as sellers) and serves 351,756 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 86% of the 84 systems serving 250,001–500,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan–Dec 2026, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 8.0 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
