How hard is the water in Luce County, MI?

1.9 grains per gallon

You do not need a softener here.

The median hardness measured in Luce County, MI is 32 mg/L as calcium carbonate, which is 1.9 gpg. That is soft on the USGS scale. It comes from 33 samples at 11 sites between 1990 and 2010, drawn from every sampling site in the county, wells and surface water together.

How much it varies here

Half the sites came in between 1.5 and 5 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

You can skip the softener. At 1.9 gpg the most a softener would fix is the odd water spot. If a salesperson in Luce County says otherwise, ask to see their reading in grains per gallon and compare it with this one. Because Luce County straddles a decision line, check your own tap with a $10 test strip before you spend anything.
