At 29 mg/L, Kingston is 98 mg/L below the typical Pennsylvania figure of 127. None of the 10 nearest cities we track has softer water. The range nearby runs from 29 mg/L in Wilkes-Barre to 40 in Moosic.

What 29 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 29 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.
