How hard is the water in Hardee County, FL?
6 grains per gallon
Optional: a softener helps, but plenty of homes skip it.
The median hardness measured in Hardee County, FL is 102 mg/L as calcium carbonate, which is 6 gpg. That is moderately hard on the USGS scale. It comes from 23 samples at 11 sites between 1990 and 2017, 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 1.1 and 16.4 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 6 gpg this is your call. Look for white film on glasses and crust on the shower head: if you see little of either, you can live without one. If you do want one, a 24,000-grain unit is enough, so ask for that size rather than a bigger one. Because Hardee County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 0.4 to 22.1 gpg
The softest single sample on record in Hardee County was 6.4 mg/L and the hardest 378 mg/L, a 59-fold gap. The top quarter of sites read above 16.4 gpg and the bottom quarter below 1.1 gpg.
Wells 6 gpg, rivers and lakes 7.1 gpg
23 groundwater samples from 11 wells put the median at 102 mg/L. 140 surface samples from 31 sites put it at 121 mg/L. In Hardee County the rivers and lakes come out 1.1 gpg harder. Here the surface water reads harder than the wells, which often points to streams fed by limestone springs or irrigation return flow. The two sources are close, so the county figure should hold whichever one your tap is on.
What a softener would cost to run
For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 130 lb of salt a year (4 bags of 40 lb, about $23), 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 $123 a year.
