The question of whether there is a relationship between the quality of drinking water and cardiovascular health has not been resolved. Associations between water hardness and mortality rates found in national studies appear to be weak and inconsistent even when studied in smaller regional areas where extraneous variables are more uniform. Findings regarding the association between cardiovascular diseases and individual components of drinking water have not been consistent. There are several new areas of research which should be pursued. Research might focus on constituents of water which are suspected of having important biological effects. The exposure of individuals to these constituents and the more subtle effects that occur in individuals are areas that deserve particular attention. Much more information is needed on basic metabolism of magnesium, the contribution of various sources to human intake, and the human magnesium requirement. Methods should be developed for assessing magnesium requirement. Methods should be developed for assessing magnesium deficiency as a possible precursor to coronary heart disease. Until further studies are brought to bear on these problems, one cannot draw definitive conclusions regarding the relationship between water hardness and cardiovascular disease.
