Calcium (Ca) and water - Lenntech

Why is calcium present in water? Calcium is naturally present in water. It may dissolve from rocks such as limestone, marble, calcite, dolomite, gypsum, fluorite and apatite. Calcium is a determinant of water hardness, because it can be found in water as Ca 2+ ions. Magnesium is the other hardness determinant.
