Causes Of Hardness Of Water. While hard water is not a health risk, many home and business owners do find it to be a nuisance. Hardness in water occurs when water comes into contact with mineral deposits in the earth, and some of the minerals are dissolved into the water.
Water is a great solvent for calcium and magnesium, so if the minerals are present in the soil around a water-supply well, hard water may be delivered to homes.
A strange odor or taste to drinking water is often one of the first clues you have a water conditioning problem.
These deposits can make hard water unsuitable for many uses, and so a variety of means have been developed to "soften" hard water; i.e. Hard water causes scale to accumulate in pipe systems and equipment. The lime scale can build up on the inside of the pipe restricting the flow of water or causing a blockage. Hard water in Industry: It will cause build up of limescale in pipes causing reduced flow and cause pipes to need to be replaced. The presence of soluble salts of calcium and magnesium, i.e., sulphates and chlorides of calcium and magnesium cause permanent hardness in water. The hardness of water is determined primarily by the amount of calcium and magnesium it contains.
Hard water, water that contains salts of calcium and magnesium principally as bicarbonates, chlorides, and sulfates. The lime scale can build up on the inside of the pipe restricting the flow of water or causing a blockage. Temporary hardness - caused by the presence of bicarbonate salts; this can be removed by either boiling the water, which causes the salts to decompose into. Hard water causes scale to accumulate in pipe systems and equipment. Groundwater that has been in contact with porous rocks containing deposits of minerals like limestone or dolomite will be very hard. Permanent hardness in water is hardness due to the presence of the chlorides, nitrates and sulphates of calcium and magnesium, which will not be precipitated by boiling.

Rainwater and distilled water are soft. Hard water causes scale to accumulate in pipe systems and equipment. This hardness is largely due to groundwater that flows over or through limestone.
