How hard is the water in Panola County, TX?

2.2 grains per gallon

You do not need a softener here.

The median hardness measured in Panola County, TX is 38 mg/L as calcium carbonate, which is 2.2 gpg. That is soft on the USGS scale. It comes from 9 samples at 9 sites between 1990 and 2020, 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 0.5 and 6 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 2.2 gpg the most a softener would fix is the odd water spot. If a salesperson in Panola County says otherwise, ask to see their reading in grains per gallon and compare it with this one. Because Panola County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 0.2 to 27.7 gpg

The softest single sample on record in Panola County was 3.5 mg/L and the hardest 474 mg/L, a 135-fold gap. The top quarter of sites read above 6 gpg and the bottom quarter below 0.5 gpg. So even in a soft county, a handful of wells here produce water hard enough to scale a heater.

Wells 2.2 gpg, rivers and lakes 3 gpg

9 groundwater samples from 9 wells put the median at 38.1 mg/L. 59 surface samples from 3 sites put it at 52 mg/L. In Panola County the rivers and lakes come out 0.8 gpg harder. Here the surface water reads harder than the wells, which often points to streams fed by limestone springs or irrigation return flow. The two sources are close, so the county figure should hold whichever one your tap is on.
