New York Water Quality (2026)
Last updated: June 2026

Catskill / Delaware surface water serves NYC; older buildings statewide still have legacy lead service lines.
Our New York coverage focuses on the 5 metros below. Each city page lists the utility's water source, hardness in grains per gallon, contaminants flagged above EWG's stricter health guideline, and the whole-house system that fits that specific profile, not a generic recommendation copied across the state.
Common contaminants flagged across New York
Across the New York cities we cover, these are the contaminants most often reported above EWG's health guideline. None exceed federal EPA legal limits.
- disinfection byproducts
- lead service lines
- Chromium-6 (~2x EWG guideline)
- Lead in some older service lines
- lead service lines (older homes)

Recommended systems for New York
Most New York homes benefit from a layered setup: whole-house carbon for chlorine and taste, a softener if your CCR shows hardness above 7 gpg, and a certified under-sink RO at the kitchen tap if lead, PFAS, nitrate or arsenic are flagged.

+Is New York tap water safe to drink?
Yes, by federal standards: the cities on this page all meet every EPA legal limit. The contaminants we flag sit above EWG's stricter, non-enforceable health guideline, which is the benchmark most homeowners use when deciding whether to filter further at home.
+Why is New York water hard?
Hardness comes from calcium and magnesium picked up as water moves through local geology. In New York, the values vary city by city, see the table above for your metro. Anything above 7 grains per gallon is considered hard and is where a softener starts to make a noticeable difference.
+Do I need a softener or a filter in New York?
Different problems, different tools. A whole-house carbon filter handles chlorine, chloramine and taste. A softener handles scale from hard water. Many New York homes benefit from both, and a kitchen-tap RO if lead, PFAS or nitrate appear on your CCR.
