How hard is the water in Midland County, MI?
11.2 grains per gallon
A softener will pay its way here.
The median hardness measured in Midland County, MI is 191 mg/L as calcium carbonate, which is 11.2 gpg. That is very hard on the USGS scale. It comes from 34 samples at 2 sites between 1990 and 2007, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 9.7 and 12.6 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 11.2 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 Midland County straddles a decision line, check your own tap with a $10 test strip before you spend anything.
