Water Hardness Cause Effects and SolutionsBlue Steel
Hard water is due to the presence of calcium and magnesium and is formed when water passes through or over limestone or chalk areas and calcium and magnesium ions dissolve into the water. Hardness is given in terms of the equivalent quantity of calcium carbonate (CaCO3) in milligrams per litre (mg/L) or parts per million (PPM).
