Water Hardness Definition Water hardness traditionally measures the capacity of water to react with soap, since hard water requires considerably more soap to produce lather.

It is not caused by a single substance but by a variety of dissolved metallic ions, mainly calcium and magnesium.

Hardness usually is expressed as milligrams of calcium carbonate per liter. One natural cause of hardness in drinking water is seepage and runoff through limestone, which contains calcium and magnesium. Effects There is no convincing evidence that hard water causes adverse health effects in humans, and no health-based guidelines for water hardness have been proposed.
