What are the health effects of drinking softened water? Is it beneficial to disconnect the kitchen tap ("cold-hard" water) from the softener?

Common water softeners use an exchange media to trade sodium for the calcium, magnesium and iron that is dissolved in the supply water. Depending on the hardness of the water supply, you are adding trace to small amounts of sodium while removing the hardness. The level of sodium in the water is seldom a problem. The only time that we worry about that sodium is if someone in the household is on a sodium free diet prescribed by a doctor and the source water is extremely hard. extremely hard water is water that is over 20 grains per gallon hardness or 340 mg per liter. In those situations it may be beneficial to provide the alternative hard water for drinking and cooking.
