How hard is the water in Coleman County, TX?
23.8 grains per gallon
A softener will pay its way here.
The median hardness measured in Coleman County, TX is 407 mg/L as calcium carbonate, which is 23.8 gpg. That is very hard on the USGS scale. It comes from 27 samples at 1 sites between 1990 and 1994, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 23.8 and 23.8 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 23.8 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.
