How hard is the water in Monongalia County, WV?

8.5 grains per gallon

The median hardness measured in Monongalia County, WV is 145 mg/L as calcium carbonate, which is 8.5 gpg. That is hard on the USGS scale. It comes from 71 samples at 14 sites between 1991 and 2012, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 7 and 17.1 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: high (how it is measured).

What to do next

At 8.5 gpg a softener is worth getting, mainly to protect the water heater and cut soap use. Get at least two quotes, ask each installer what grain capacity they are fitting, and check it against the sizing table below. Because Monongalia County straddles a decision line, check your own tap with a $10 test strip before you spend anything.

From 3.1 to 63.7 gpg

The softest single sample on record in Monongalia County was 53.8 mg/L and the hardest 1,090 mg/L, a 20-fold gap. The top quarter of sites read above 17.1 gpg and the bottom quarter below 7 gpg. So even here some sites draw water soft enough to need nothing at all.

Wells 15.9 gpg, rivers and lakes 8.4 gpg

3 groundwater samples from 3 wells put the median at 272 mg/L. 68 surface samples from 11 sites put it at 143.5 mg/L. In Monongalia County the wells come out 7.5 gpg harder. Groundwater sits in contact with rock for years and picks up calcium and magnesium as it goes, so wells usually read harder. A utility here that draws from the river 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 185 lb of salt a year (5 bags of 40 lb, about $33), 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 $133 a year.
