How hard is the water in Henry County, GA?

1.9 grains per gallon

You do not need a softener here.

The median hardness measured in Henry County, GA is 33 mg/L as calcium carbonate, which is 1.9 gpg. That is soft on the USGS scale. It comes from 462 samples at 18 sites between 1999 and 2026, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 1.1 and 2.3 gpg. The whole middle of that range gives the same answer, so a test of your own tap is unlikely to change it. Confidence in the county figure: high (how it is measured).

What to do next

You can skip the softener. At 1.9 gpg the most a softener would fix is the odd water spot. If a salesperson in Henry County says otherwise, ask to see their reading in grains per gallon and compare it with this one.
