How hard is the water in Kaufman County, TX?
7.8 grains per gallon
A softener is worth it here.
The median hardness measured in Kaufman County, TX is 133 mg/L as calcium carbonate, which is 7.8 gpg. That is hard on the USGS scale. It comes from 227 samples at 4 sites between 1990 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 7.6 and 7.8 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: medium (how it is measured).
What to do next
At 7.8 gpg a softener is worth getting, mainly to protect the water heater and cut soap use. Get at least two quotes, ask each installer what grain capacity they are fitting, and check it against the sizing table below.
