What is the hardness of Pocatello's water?
Pocatello's water is very hard and averages 350 parts per million, which is the equivalent of 20.5 grains per gallon (water above 10 grains per gallon is considered hard). Water hardness is mainly caused by an excess of calcium and magnesium in the water. Hardness is reported as the equivalent amount of calcium carbonate (CaCO3). Scale formation and excessive soap consumption are the main concerns with hardness. Consumers may notice an increased difficulty in cleaning and laundering tasks, decreased efficiency of water heaters and other water-using appliances, and white/chalky deposits on dishes. While these problems can be frustrating, water hardness is not a safety issue. Hard water is safe for drinking, cooking, and other household uses. A water softener may address many concerns associated with hard water, but it is not recommended to drink soft water.
