- Utility report
Tap water in Tucker has about 18 mg/L of hardness, which is 1.0 grains per gallon. On the USGS scale that counts as soft. The number comes from Dekalb County, dated September 2025.
Tucker sits close to the typical Georgia figure of 28 mg/L. None of the 10 nearest cities we track has softer water. The range nearby runs from 18 mg/L in Clarkston to 24 in Decatur.
What 18 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 18 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.
