Water comes from Ctwc - Shoreline Region-Guilford System
Ctwc - Shoreline Region-Guilford System supplies Old Saybrook: about 89% of residents live in its service area. About 11% 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 Ctwc - Shoreline Region-Chester System and Regional Water Authority as sellers) and serves 33,975 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–Dec 2026, was 0.0 ppb, below the 15 ppb action level that applied. The highest in five years was 3.0 ppb. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
