How hard is the water in Lee County, GA?
7.1 grains per gallon
A softener is worth it here.
The median hardness measured in Lee County, GA is 122 mg/L as calcium carbonate, which is 7.1 gpg. That is hard on the USGS scale. It comes from 26 samples at 10 sites between 1991 and 2022, drawn from groundwater wells, which is what most taps and private wells in the county draw on.
How much it varies here
Half the sites came in between 5.9 and 11.2 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: medium (how it is measured).
What to do next
At 7.1 gpg a softener is worth getting, mainly to protect the water heater and cut soap use. Get at least two quotes, ask each installer what grain capacity they are fitting, and check it against the sizing table below. Because Lee County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 3.0 to 13.8 gpg
The softest single sample on record in Lee County was 51.3 mg/L and the hardest 236 mg/L, a 5-fold gap. The top quarter of sites read above 11.2 gpg and the bottom quarter below 5.9 gpg. So even here some sites draw water soft enough to need nothing at all.
Wells 7.1 gpg, rivers and lakes 1.2 gpg
26 groundwater samples from 10 wells put the median at 121.5 mg/L. 110 surface samples from 9 sites put it at 20 mg/L. In Lee County the wells come out 5.9 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.
What a softener would cost to run
For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 155 lb of salt a year (4 bags of 40 lb, about $28), and roughly 2,346 gallons of regeneration water. Installed, most units run $1,000 to $4,500; spread over 15 years with salt, that is about $128 a year.
