How hard is the water in Nacogdoches County, TX?

0.3 grains per gallon

You do not need a softener here.

The median hardness measured in Nacogdoches County, TX is 5 mg/L as calcium carbonate, which is 0.3 gpg. That is soft on the USGS scale. It comes from 7 samples at 7 sites between 2004 and 2015, 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 0.2 and 1.1 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

You can skip the softener. At 0.3 gpg the most a softener would fix is the odd water spot. If a salesperson in Nacogdoches County says otherwise, ask to see their reading in grains per gallon and compare it with this one.
