Jonesboro water measures 60 mg/L (3.5 gpg) of hardness, soft by USGS standards. TapWaterData worked it out from the calcium and magnesium levels the local utility reports (September 2024).
At 60 mg/L, Jonesboro is 21 mg/L above the typical Arkansas figure of 39. Of the 10 nearest cities we track, 6 have softer water and 4 have harder. The range nearby runs from 12 mg/L in Paragould to 310 in Forrest City.
What 60 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 60 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.
