How hard is the water in Telfair County, GA?
1 grains per gallon
You do not need a softener here.
The median hardness measured in Telfair County, GA is 17 mg/L as calcium carbonate, which is 1 gpg. That is soft on the USGS scale. It comes from 134 samples at 11 sites between 1993 and 2025, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 0.9 and 2.5 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 gpg the most a softener would fix is the odd water spot. If a salesperson in Telfair County says otherwise, ask to see their reading in grains per gallon and compare it with this one.

From 0.6 to 8.9 gpg
The softest single sample on record in Telfair County was 10.4 mg/L and the hardest 152 mg/L, a 15-fold gap. The top quarter of sites read above 2.5 gpg and the bottom quarter below 0.9 gpg.
Wells 7.8 gpg, rivers and lakes 1 gpg
3 groundwater samples from 2 wells put the median at 134.3 mg/L. 131 surface samples from 9 sites put it at 16.6 mg/L. In Telfair County the wells come out 6.8 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. A utility here that draws from the river can deliver noticeably different water from a private well next door.
