How hard is the water in Hutchinson County, TX?

18.4 grains per gallon

The median hardness measured in Hutchinson County, TX is 315 mg/L as calcium carbonate, which is 18.4 gpg. That is very hard on the USGS scale. It comes from 40 samples at 6 sites between 1990 and 2020, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 13.4 and 20.7 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 18.4 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.

From 11.6 to 21.8 gpg

The softest single sample on record in Hutchinson County was 198.5 mg/L and the hardest 374 mg/L, a 2-fold gap. The top quarter of sites read above 20.7 gpg and the bottom quarter below 13.4 gpg.

Wells 12.5 gpg, rivers and lakes 20.7 gpg

6 groundwater samples from 3 wells put the median at 213.5 mg/L. 34 surface samples from 3 sites put it at 354 mg/L. In Hutchinson County the rivers and lakes come out 8.2 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.

What a softener would cost to run

For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 402 lb of salt a year (11 bags of 40 lb, about $72), and roughly 2,346 gallons of regeneration water. Installed, most units run $1,000 to $4,500; spread over 15 years with salt, that is about $172 a year.
