"""I strongly recommend this book for all those interested in Ca and Mg in drinking water. It is the first book of its kind presenting these important elements. I hope that it will be followed by a new book on more global aspects."" Dr Olle Selinus Linneaus University Sweden, former Geological Survey of Sweden"
