How hard is the water in Gonzales County, TX?

1.4 grains per gallon

You do not need a softener here.

The median hardness measured in Gonzales County, TX is 24 mg/L as calcium carbonate, which is 1.4 gpg. That is soft on the USGS scale. It comes from 8 samples at 7 sites between 1996 and 2021, 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 1.1 and 5.9 gpg. That spread crosses a decision line, so some homes here land on a different answer. A $10 test strip on your own tap settles it. Confidence in the county figure: medium (how it is measured).

What to do next

You can skip the softener. At 1.4 gpg the most a softener would fix is the odd water spot. If a salesperson in Gonzales County says otherwise, ask to see their reading in grains per gallon and compare it with this one. Because Gonzales County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 0.9 to 9.5 gpg

The softest single sample on record in Gonzales County was 14.7 mg/L and the hardest 162 mg/L, an 11-fold gap. The top quarter of sites read above 5.9 gpg and the bottom quarter below 1.1 gpg.

Wells 1.4 gpg, rivers and lakes 13.5 gpg

8 groundwater samples from 7 wells put the median at 24 mg/L. 25 surface samples from 2 sites put it at 231.5 mg/L. In Gonzales County the rivers and lakes come out 12.1 gpg harder. Here the surface water reads harder than the wells, which often points to streams fed by limestone springs or irrigation return flow. A utility here that draws from the aquifer can deliver noticeably different water from a private well next door.
