- Utility report
Tap water in Elmsford has about 17 mg/L of hardness, which is 1.0 grains per gallon. On the USGS scale that counts as soft. The number comes from Greenburgh Consolidated WD #1, dated August 2025.
Elmsford sits 14 mg/L below the typical New York figure of 31. Of the 10 nearest cities we track, 3 have softer water and 5 have harder. The range nearby runs from 6 mg/L in Irvington to 32 in Pleasantville.
What 17 mg/L means at home
Soap and shampoo lather with very little product. Kettles and showerheads stay mostly free of white crust.
Some people notice that soap feels slow to rinse off in soft water. That slippery feel is normal and harmless.
Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.
What to do about it
Nothing, as far as hardness goes. At 17 mg/L a softener would have almost nothing to remove.
Carbon filter
If the water tastes of chlorine, a pitcher or faucet carbon filter takes care of that. It does not change hardness.
