How hard is the water in Parmer County, TX?

11.7 grains per gallon

The median hardness measured in Parmer County, TX is 200 mg/L as calcium carbonate, which is 11.7 gpg. That is very hard on the USGS scale. It comes from 3 samples at 3 sites between 2001 and 2016, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 8.8 and 13.8 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: low (how it is measured).

What to do next

At 11.7 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. Because Parmer County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

What a softener would cost to run

For a household of 3, a 24,000-grain unit covers a week between regenerations. Expect about 255 lb of salt a year (7 bags of 40 lb, about $46), 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 $146 a year.
