How hard is the water in Goshen County, WY?
11.4 grains per gallon
A softener will pay its way here.
The median hardness measured in Goshen County, WY is 195 mg/L as calcium carbonate, which is 11.4 gpg. That is very hard on the USGS scale. It comes from 35 samples at 35 sites between 1990 and 2012, 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 4.6 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: high (how it is measured).
What to do next
At 11.4 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 Goshen County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 0.4 to 24.0 gpg
The softest single sample on record in Goshen County was 7.6 mg/L and the hardest 411 mg/L, a 54-fold gap. The top quarter of sites read above 16.4 gpg and the bottom quarter below 4.6 gpg. So even here some sites draw water soft enough to need nothing at all.
Wells 11.4 gpg, rivers and lakes 14 gpg
35 groundwater samples from 35 wells put the median at 195 mg/L. 5 surface samples from 3 sites put it at 240.5 mg/L. In Goshen County the rivers and lakes come out 2.6 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 249 lb of salt a year (7 bags of 40 lb, about $45), 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 $145 a year.
