Santa Clara water measures 19 mg/L (1.1 gpg) of hardness, soft by USGS standards. The number comes from Eugene Water & Electric Board, dated September 2025.
At 19 mg/L, Santa Clara is close to the typical Oregon figure of 24 mg/L. Of the 10 nearest cities we track, 4 have softer water and 4 have harder. The range nearby runs from 16 mg/L in Salem to 95 in Keizer.
What 19 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 19 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.
