Source of Calcium in Water: Calcium in water is the major cause of water hardness and is usually in the range of 5-500 mg/L. When water passes through certain rocks and geographical formations, it gathers contaminants and minerals including calcium. Calcium is derived from nearly all rocks, but the greatest concentrations come from limestone and gypsum. Calcium in water occurs when water percolates through limestone or other soluble carbonate rocks; it partially dissolves the rock and then forms hard water.
Symptoms of Calcium: Calcium in water does not have adverse health affects. However, hardness or calcium in water does affect everything else in your home. Soaps and detergents will not be as effective if they are being used in hard water. Because they do not dissolve as easily, more soap and detergent will have to be used. The clothes will not get as clean because the dirt will get trapped underneath a level of soap scum. Dishes, windows, and cars washed in hard water will have spots because of the mineral deposits left behind after the water dries. Calcium and hard water will also cause scale buildups in pipes, leading to clogged and damaged plumbing. Calcium reduction is required in water used for cooling towers, metal finishing, textile operations, and boiler feed applications.
Filtration Solutions for Calcium: Calcium in water, as with all water hardness, can be removed with a water softener system. For those with health conditions that require less sodium, a reverse osmosis system will also remove 95-98% of the calcium in the water.
