Calcium presence in water supplies results from passage over deposits of limestone, dolomite, gypsum and gypsiferous shale. Its concentration may extend from 0 to several hundred milligrams per liter, depending on its source and treatment.

Calcium in water as carbonate is one of the primary components of water hardness which can cause pipe or tube scaling. The HI 758 Calcium Checker HC is extremely simple to use.
