Hard Water, Calcium Carbonate Levels in Indiana

Typically, Central Indiana water has levels of calcium carbonate—the term used to express water hardness—ranging from 200-350 milligrams per liter, or parts per million. This translates to about 12-20 grains per gallon (gpg), the measure often referred to in determining water softener settings.

Water hardness can vary greatly depending on location and source.

Hard water is unpleasant for many reasons—using more soaps and detergents, dingy appearance on clothes, stains and scale buildup on appliances, sinks, and tubs, and even boiler scale that causes higher utility usage and bills.
