How hard is the water in Potter County, TX?

22.7 grains per gallon

The median hardness measured in Potter County, TX is 388 mg/L as calcium carbonate, which is 22.7 gpg. That is very hard on the USGS scale. It comes from 227 samples at 2 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 19.7 and 25.7 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: low (how it is measured).

What to do next

At 22.7 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 16.6 to 28.7 gpg

The softest single sample on record in Potter County was 285 mg/L and the hardest 491.5 mg/L, a 2-fold gap. The top quarter of sites read above 25.7 gpg and the bottom quarter below 19.7 gpg.

What a softener would cost to run

For a household of 3, a 32,000-grain unit covers a week between regenerations. Expect about 495 lb of salt a year (13 bags of 40 lb, about $89), 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 $189 a year.
