New York Water Quality (2026)

Catskill / Delaware surface water serves NYC; older buildings statewide still have legacy lead service lines.

Our New York coverage focuses on the 2 metros below: Buffalo, New York. Each city page lists the utility's water source, hardness in grains per gallon, any contaminants flagged above EWG's stricter health guideline, and the whole-house system type that matches that specific profile, not a generic recommendation copied across the state.

If your New York city is not in the list yet, the nearest covered metro is usually a reasonable proxy: regional source water and treatment plants are typically shared across nearby municipalities. Private wells in New York are a different story and need a mail-in lab panel, the utility CCR will not apply.
