See also: Water softening. Soft water is surface water that contains low concentrations of ions and in particular is low in ions of calcium and magnesium. Soft water naturally occurs where rainfall and the drainage basin of rivers are formed of hard, impervious and calcium poor rocks.ecause soft water has few calcium ions, there is no inhibition of the action of soaps and no soap scum is formed in normal washing. Similarly, soft water produces no calcium deposits in water heating systems. Water that is not soft is referred to as hard water.
Furthermore, there is also no need to worry about a water softener depriving your water of its essential minerals. It will only remove minerals that can cause the water to be hard and damaging to pipes, such as magnesium, calcium, and iron.In general, there are no significant or immediate health risks that result from drinking softened water.he minerals in the water are what make it considered âhard water.â If youâve ever noticed that soap wasnât bubbling or dissolving in your water, this would be indicative hard water that was full of minerals. A water softener can improve the quality of your laundry, cleaning, bathing, and steam-powered appliances.
