- Calculated from utility data
Tap water in Kennett has about 57 mg/L of hardness, which is 3.3 grains per gallon. On the USGS scale that counts as soft. TapWaterData worked it out from the calcium and magnesium levels the local utility reports (December 2020).
At 57 mg/L, Kennett is 64 mg/L below the typical Missouri figure of 121. Of the 10 nearest cities we track, 1 has softer water and 9 have harder. The range nearby runs from 21 mg/L in Caruthersville to 565 in Park Hills.
What 57 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 57 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.
