Hard water is water that has high mineral content. Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates.
Why is it dangerous?
Hard water has no health risk but can cause many problems to a home or business. Hard water can lead to mineral build up inside of piping. In an industrial setting water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. Hard water lowers the effectiveness of soaps, so this causes problems in laundering clothes, washing dishes, and even bathing.
Hard water can lead to scale buildup in plumbing systems. You will notice mineral deposits, stains, or a white film on surfaces like porcelain, enamel, china, stainless steel, tile, chrome, fiberglass, and glass. You may also notice stains or build-up on bathroom fixtures, dishes, and sinks. Hard water may cause shower heads to clog, and leave high levels of “soap scum” behind. Washing clothes in hard water can make them look dingy, feel scratchy, damage the fibers, and even shorten the life of your clothes by as much as 40%. Hard water may also irritate skin and leave you hair dull and lifeless.
