As water evaporates, the concentration of minerals increases and creates saturated water, forming scale. Since more than 80 percent of geographic locations in the United States have hard water, according to the U.S. Geological Survey, many homeowners and landlords look into installing water softeners to protect their homes and appliances from the damaging effects of scale buildup.
