What is Hard Water?

All water begins as soft water. As it falls through the atmosphere and filters through rocks and soil, water picks up invisible minerals. The presence of these minerals in water makes household cleaning tasks more difficult. In fact, the phrase, “hard water” was coined to describe this water which is “hard” to use.

According to the Kent County Health Department, water over 250 milligrams per liter (15 grains per gallon) will cause build up of lime on fixtures, soap scum and some corrosion.

Iron content over .5 will cause staining, cloudy water along with taste and odor concerns.

Most people, see water issues build up starting at 10 grains per gallon and .3 parts of iron. Well water in Western Michigan is generally of a quality that benefits the home owner to condition with water treatment equipment.

Many commercial and industrial applications, even on municipal water, cannot tolerate hardness in the 6-8 grain per gallon level and benefit from water treatment equipment.

Local municipalities hardness levels:

  • Grand Rapids: 6-8 grains
  • Plainfield Township: 8-10 grains
  • City of Caledonia: 20-24 grains
  • City of Rockford: 20-25 grains
