How hard is the water in Gilchrist County, FL?
12.6 grains per gallon
A softener will pay its way here.
The median hardness measured in Gilchrist County, FL is 216 mg/L as calcium carbonate, which is 12.6 gpg. That is very hard on the USGS scale. It comes from 137 samples at 23 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 9.9 and 14.9 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
At 12.6 gpg a softener pays its way here. Before you buy, check the quoted unit's grain capacity against the sizing table below, and ask whether it regenerates on demand, which uses less salt than a timer. Call your utility for its own report if you are on city water. Because Gilchrist County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 7.4 to 20.4 gpg
The softest single sample on record in Gilchrist County was 126.3 mg/L and the hardest 348.5 mg/L, a 3-fold gap. The top quarter of sites read above 14.9 gpg and the bottom quarter below 9.9 gpg.
Wells 12.6 gpg, rivers and lakes 7.9 gpg
137 groundwater samples from 23 wells put the median at 216 mg/L. 115 surface samples from 22 sites put it at 134.6 mg/L. In Gilchrist County the wells come out 4.7 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 276 lb of salt a year (7 bags of 40 lb, about $50), 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 $150 a year.
