Hard water - Wikipedia

Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is
