Marlboro has no town government of its own, so Ulster County runs its elections and most services, and its children attend Marlboro Central School District. Tap water in most of Marlboro comes from Marlborough Water District, which has a clean five-year EPA record (about 22% of systems its size had a health-based violation) and a latest lead result below detection.

Water comes from Marlborough Water District
Marlborough Water District supplies Marlboro: about 54% of residents live in its service area. About 46% 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 Newburgh Consolidated WD as seller) and serves 3,248 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 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.
