Othello water measures 33 mg/L (1.9 gpg) of hardness, soft by USGS standards. TapWaterData worked it out from the calcium and magnesium levels the local utility reports (August 2022).
At 33 mg/L, Othello is close to the typical Washington figure of 36 mg/L. None of the 10 nearest cities we track has softer water. The range nearby runs from 33 mg/L in West Richland to 268 in Pasco.
What 33 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 33 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.
