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. ... Hard water can take a toll on household appliances as well and use up more energy.
