    Hard water is water that has a high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, [1] which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Drinking hard water may have moderate health benefits.

  6. Water hardness is measured in terms of a unit called “parts per million” (ppm) or “milligrams per liter” (mg/L). There are two main methods of measuring water hardness: titration and test strips.
