💧 New York, NY Water Quality at a Glance
NYC's unfiltered Catskill/Delaware watershed water is one of the world's great municipal water systems. Soft, well-managed, and consistently well-rated.
Is New York Water Hard or Soft?
At 1.4 GPG (23 PPM), New York tap water is soft — no softener needed. You're in good shape for appliances, though a carbon filter can improve taste.
Water hardness is measured in grains per gallon (GPG) or parts per million (PPM). The EPA's informal guidance considers water above 7 GPG (121 PPM) "hard," and above 10 GPG (171 PPM) "very hard." Here's where New York falls:
| Classification | GPG | PPM | New York Status |
|---|---|---|---|
| Soft | < 1 | < 17 | ← New York is here |
| Moderately Hard | 3.5–7 | 61–120 | — |
| Hard | 7–10 | 121–171 | — |
| Very Hard | > 10 | > 171 | — |
What Contaminants Are in New York Water?

- Total Trihalomethanes
- Haloacetic acids
- Manganese

How Does New York Water Taste?
Famously clean, mild, slightly mineral — historically one of the best in the US. Soft water at 24 PPM is clean and pleasant with little mineral character. For coffee and tea, filtered water will improve flavor extraction.
What's the Best Water Filter for New York?
Recommendation: Brita/carbon pitcher sufficient for most uses; certified lead filter for older buildings.
Here's how to think about filtration in New York:
- For scale/hardness (24 PPM): Hardness is low enough that a softener isn't urgent. A simple carbon filter handles most taste concerns.
- For drinking water quality: A pitcher or faucet-mount carbon filter is sufficient for taste improvement. Brita, ZeroWater, or Pur are popular choices.
- For PFAS: PFAS has not been detected in New York's main supply — standard carbon filtration is adequate.
- For lead: Lead at 5.0 ppb indicates some risk, especially in older homes with lead service lines. Use an NSF/ANSI 53-certified lead reduction filter — not all filters remove lead.
