- Calculated from utility data
Tap water in Troy has about 12 mg/L of hardness, which is 0.7 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 (May 2022). Reports for this system disagree, with values from 12 to 29 mg/L.
At 12 mg/L, Troy is 61 mg/L below the typical Alabama figure of 73. Of the 10 nearest cities we track, 1 has softer water and 9 have harder. The range nearby runs from 7 mg/L in Greenville to 173 in Headland.
What 12 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 12 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.
