'The Magnesium Factor' by Drs. Seelig and Rosanoff details the huge health consequences of dietary calcium excess when combined with dietary magnesium deficiency. It is known that Ca and Mg contents in one's water will strongly influence the total dietary intake ratio between the two minerals. A table in the book shows Ca and Mg content for water in various U.S. cities. For Denver, where I live, the ratio is about 4 to 1, Ca to Mg. Startling! Was this accurate? Could this be the reason I developed a-fib only after living in Denver for 10 years, when my first 6o odd years had been without a quiver? Why my 'cure' came largely from overcoming a Mg deficiency? I went to denverwater.org for facts. (By the way, a graph in the book shows 4:1 dietary Ca:Mg correlating with the world's highest death rate from ishemic heart disease.)

Denver domestic water is largely 'surface runoff' from mountain snow and rain. There are three treatment plants delivering water to the 'taps'. The following numbers for Ca and Mg are from
