How hard is the water in Okeechobee County, FL?

18.1 grains per gallon

The median hardness measured in Okeechobee County, FL is 310 mg/L as calcium carbonate, which is 18.1 gpg. That is very hard on the USGS scale. It comes from 8 samples at 6 sites between 1990 and 2019, 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 16.3 and 20.3 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: medium (how it is measured).

What to do next

At 18.1 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.

From 9.9 to 60.2 gpg

The softest single sample on record in Okeechobee County was 170 mg/L and the hardest 1,030 mg/L, a 6-fold gap. The top quarter of sites read above 20.3 gpg and the bottom quarter below 16.3 gpg.

Wells 18.1 gpg, rivers and lakes 6.7 gpg

8 groundwater samples from 6 wells put the median at 309.5 mg/L. 430 surface samples from 80 sites put it at 115 mg/L. In Okeechobee County the wells come out 11.4 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. 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 395 lb of salt a year (10 bags of 40 lb, about $71), 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 $171 a year.
