What is hard water ?

                                     What is hard water ?

Water described "hard" is high in dissolved minerals especially Calcium and Magnesium . Hard water is not only a health risk but also a nuisance because of mineral build up on fixtures and poor soap and detergent performance as it is hard to get foam.
Water is a good solvent and picks up impurities quickly . As water moves through soil and rock , it dissolves small amount of minerals and holds them in solution. Calcium and Magnesium sulphates are the two most common minerals that make water "hard" .
The degree of hardness becomes greater as the calcium and magnesium content increases. We can add washing soda ( Sodium Carbonate ) to make it to lose its hardness.
