This article will look at the differences between the two types of water, as well as the pros and cons of each and what to know about water softening. The hardness of water is determined primarily by the amount of calcium and magnesium it contains. Higher levels of these and other minerals make water hard.

These deposits can make hard water unsuitable for many uses, and so a variety of means have been developed to "soften" hard water; i.

Hard water contains a high amount of minerals, and soft water contains little to none. Water accumulates dissolved solids as it moves through rocks and other substrates, like limestone, gypsum or dolomite. Calcium and magnesium are particularly soluble in water, and if these naturally occurring minerals are within the geographical area, the residents surrounding the water source will have hard water.

    Hard water is water that contains an appreciable quantity of dissolved minerals (like calcium and magnesium). Soft water is treated water in which the only ion is sodium. As rainwater falls, it is naturally soft. On the other hand, soft water tastes salty and is sometimes not suitable for drinking.
