- Utility report
The water in Bethpage carries roughly 10 mg/L of dissolved calcium and magnesium, or 0.6 grains per gallon. That is soft water. The number comes from South Farmingdale WD, dated September 2025.
At 10 mg/L, Bethpage is 21 mg/L below the typical New York figure of 31. None of the 10 nearest cities we track has softer water. The range nearby runs from 10 mg/L in Plainedge to 54 in Plainview.
What 10 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 10 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.
