- Utility report
Tap water in Rancho Calaveras has about 54 mg/L of hardness, which is 3.2 grains per gallon. On the USGS scale that counts as soft. The number comes from CCWD - Jenny Lind, dated April 2023. Reports for this system disagree, with values from 54 to 75 mg/L.
At 54 mg/L, Rancho Calaveras is 67 mg/L below the typical California figure of 121. Of the 10 nearest cities we track, 6 have softer water and 4 have harder. The range nearby runs from 4 mg/L in Lodi to 196 in Riverbank.
What 54 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 54 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.
