How hard is the water in Randall County, TX?
19.2 grains per gallon
A softener will pay its way here.
The median hardness measured in Randall County, TX is 328 mg/L as calcium carbonate, which is 19.2 gpg. That is very hard on the USGS scale. It comes from 2 samples at 2 sites between 2001 and 2001, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 17.3 and 21 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: low (how it is measured).
What to do next
At 19.2 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.

What a softener would cost to run
For a household of 3, a 32,000-grain unit covers a week between regenerations. Expect about 418 lb of salt a year (11 bags of 40 lb, about $75), 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 $175 a year.
