- Utility report
Tap water in Circleville has about 46 mg/L of hardness, which is 2.7 grains per gallon. On the USGS scale that counts as soft. The number comes from Twin Pines MHP, dated December 2022. Reports for this system disagree, with values from 4 to 46 mg/L.
At 46 mg/L, Circleville is 67 mg/L below the typical Ohio figure of 113. None of the 10 nearest cities we track has softer water. The range nearby runs from 97 mg/L in Groveport to 276 in Chillicothe.
What 46 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 46 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.
