How hard is the water in Morgan County, IN?
17 grains per gallon
A softener will pay its way here.
The median hardness measured in Morgan County, IN is 291 mg/L as calcium carbonate, which is 17 gpg. That is very hard on the USGS scale. It comes from 384 samples at 27 sites between 1990 and 2014, drawn from every sampling site in the county, wells and surface water together.
How much it varies here
Half the sites came in between 14.8 and 18.4 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: high (how it is measured).
What to do next
At 17 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 7.6 to 23.1 gpg
The softest single sample on record in Morgan County was 130 mg/L and the hardest 395 mg/L, a 3-fold gap. The top quarter of sites read above 18.4 gpg and the bottom quarter below 14.8 gpg.
Wells 21.8 gpg, rivers and lakes 16.4 gpg
15 groundwater samples from 4 wells put the median at 372.8 mg/L. 369 surface samples from 23 sites put it at 280 mg/L. In Morgan County the wells come out 5.4 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 371 lb of salt a year (10 bags of 40 lb, about $67), 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 $167 a year.
