WATER STEWARDSHIP INFORMATION SERIES Hardness in Groundwater February 2007 What is water hardness? Water hardness is primarily the amount of calcium and magnesium‚ and to a lesser extent‚ iron in the water. Water hardness is measured by adding up the concentrations of calcium‚ magnesium and converting this value to an equivalent concentration of calcium carbonate (CaCO 3 ) in milligrams per litre (mg/L) of water. The Guidelines for Canadian Drinking Water Quality Hardness divide hardness
