How hard is the water in Wayne County, UT?
21 grains per gallon
A softener will pay its way here.
The median hardness measured in Wayne County, UT is 359 mg/L as calcium carbonate, which is 21 gpg. That is very hard on the USGS scale. It comes from 244 samples at 36 sites between 1990 and 2021, 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 15.9 and 31.5 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: high (how it is measured).
What to do next
At 21 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 4.9 to 68.6 gpg
The softest single sample on record in Wayne County was 83.3 mg/L and the hardest 1,175 mg/L, a 14-fold gap. The top quarter of sites read above 31.5 gpg and the bottom quarter below 15.9 gpg.
Wells 21 gpg, rivers and lakes 14.3 gpg
244 groundwater samples from 36 wells put the median at 359.1 mg/L. 1,122 surface samples from 61 sites put it at 245.2 mg/L. In Wayne County the wells come out 6.7 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 32,000-grain unit covers a week between regenerations. Expect about 458 lb of salt a year (12 bags of 40 lb, about $82), 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 $182 a year.
