Soft water is surface water that contains low concentrations of ions and in particular is low in ions of calcium and magnesium. Soft waternaturally occurs where rainfall and the drainage basin of rivers are formed of hard, impervious and calcium-poor rocks.

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
