How to Measure Water Hardness Pelican Water
Just because test results indicate hard water doesn't mean you have to live with the damage water hardness causes. Traditionally, salt-based water softeners have been used to treat hard water by replacing hard water mineral ions with sodium ions. While effective, salt-based systems discharge significant amounts of briny wastewater, which has a negative effect on the environment and local

Water Hardness - Department of Chemistry
2014-9-29 · This precipitate, known as scale, coats the vessels in which the water is heated, producing the mineral deposits on your cooking dishes. In small quantities, these deposits are not harmful, but they may be frustrating to try to clean. As these deposits build up, however, they reduce the efficiency of heat transfer, so food may not cook as evenly or quickly in pans with large scale deposits.
