By regression analysis of 1949‐51 data with average hardness varying from 17 to 299: ppm, this study has established the statistical significance of the relationship between water hardness and the death rate of white males aged 45‐64 to be greater than 99.9 per cent. It therefore appears, both on a national as well as on a local scale, that the presence of calcium or magnesium, or other substances normally present or absent when calcium or magnesium is present, are responsible for substantial reductions in the death rates from cardiovascular disease.
