How hard is the water in Liberty County, GA?
3 grains per gallon
You do not need a softener here.
The median hardness measured in Liberty County, GA is 51 mg/L as calcium carbonate, which is 3 gpg. That is soft on the USGS scale. It comes from 232 samples at 28 sites between 1997 and 2020, 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 and 44.1 gpg. That spread crosses a decision line, so some homes here land on a different answer. A $10 test strip on your own tap settles it. Confidence in the county figure: high (how it is measured).
What to do next
You can skip the softener. At 3 gpg the most a softener would fix is the odd water spot. If a salesperson in Liberty County says otherwise, ask to see their reading in grains per gallon and compare it with this one. Because Liberty County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 0.6 to 260.0 gpg
The softest single sample on record in Liberty County was 9.9 mg/L and the hardest 4,450 mg/L, a 449-fold gap. The top quarter of sites read above 44.1 gpg and the bottom quarter below 1 gpg. So even in a soft county, a handful of wells here produce water hard enough to scale a heater.
Wells 4.8 gpg, rivers and lakes 2.4 gpg
4 groundwater samples from 4 wells put the median at 81.5 mg/L. 228 surface samples from 24 sites put it at 40.5 mg/L. In Liberty County the wells come out 2.4 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. The two sources are close, so the county figure should hold whichever one your tap is on.
