A softener will pay its way here.
The median hardness measured in Throckmorton County, TX is 636 mg/L as calcium carbonate, which is 37.2 gpg. That is very hard on the USGS scale. It comes from 79 samples at 1 sites between 2011 and 2023, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 37.2 and 37.2 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 37.2 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.
