How hard is the water in Uinta County, WY?
14.5 grains per gallon
A softener will pay its way here.
The median hardness measured in Uinta County, WY is 248 mg/L as calcium carbonate, which is 14.5 gpg. That is very hard on the USGS scale. It comes from 7 samples at 7 sites between 1990 and 2014, 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 2.1 and 22.2 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 14.5 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 Uinta County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 0.4 to 126.8 gpg
The softest single sample on record in Uinta County was 7.4 mg/L and the hardest 2,170 mg/L, a 293-fold gap. The top quarter of sites read above 22.2 gpg and the bottom quarter below 2.1 gpg. So even here some sites draw water soft enough to need nothing at all.
Wells 14.5 gpg, rivers and lakes 10.2 gpg
7 groundwater samples from 7 wells put the median at 248 mg/L. 327 surface samples from 15 sites put it at 175.2 mg/L. In Uinta County the wells come out 4.3 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 316 lb of salt a year (8 bags of 40 lb, about $57), 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 $157 a year.
