Is 
                Hard Water Bad For You?
              While 
                the effects on one's health are fairly limited Hard Water does 
                have negative impacts on the home and industry. The mineral build-up 
                on plumbing, and heating elements of household products affects 
                their performance and service life. However, the calcium and magnesium 
                in drinking water is actually beneficial to us.
                
                Many people in the USA and other countries need to soften their 
                water. Standard salt fed "ionic exchange" or "reverse 
                osmosis" water softener systems remove these beneficial minerals 
                and add potentially unhealthy sodium to the water from salt. The 
                Eddy electronic water treatment device, however, does not remove 
                the healthy calcium from drinking water, nor does it add any chemicals 
                to the water.
                
                The National Research Council proclaims that drinking hard water 
                can partly satisfy ones calcium and magnesium dietary needs. It 
                also states that in instances where calcium and magnesium concentrate 
                are very high, this can be the primary magnesium and calcium contributor 
                to the human diet.
                
                Researchers are forever studying the relationship between the 
                hardness of water and mortality rates as a result of cardiovascular 
                disease. Such studies have been 'epidemiological studies,' 
                
                There are some studies which suggest a definite relationship between 
                hard water and lower cardiovascular disease mortality. However 
                others do not suggest a relationship. The National Research Council 
                deems results at this time to be inconclusive.
