Calcium and magnesium are abundant in groundwater, but the role of groundwater as the essential source of these important nutrients is very often neglected. Hydrogeochemical studies are focused mainly on distribution and behaviour of constituents that cause deterioration of water quality, such as: nitrate, nitrite or iron, manganese. Therefore, most recent books and papers concentrate mainly on these water components and only a small number of papers describe results of groundwater studies on valuable water components as calcium or magnesium. Calcium and magnesium are of great importance to human health and inadequate intake of either nutrient can impair health. The main objective of this IAH Selected Papers book is to present the results of the studies on calcium and magnesium in groundwater as well as their importance for human health.

Summary
Calcium and magnesium are abundant in groundwater, but the role of groundwater as the essential source of these important nutrients is very often neglected. Hydrogeochemical studies have focused mainly on the distribution and behaviour of constituents that cause deterioration of water quality, such as: nitrate, nitrite or iron and manganese. Therefore, most recent books and papers concentrate mainly on these constituents and only a small number of papers describe the results of groundwater studies on other important water components such as calcium or magnesium. Calcium and magnesium are of great importance to human wellbeing and inadequate intake of either nutrient can impair health. The main objective of this book is to present a selection of studies on calcium and magnesium in groundwater and to highlight their importance for human health.
The chapters in this book are written by hydrogeologists and hydrochemists as well as medical doctors and include: methods of investigation of calcium and magnesium in groundwaters, distribution and behaviour of calcium and magnesium in different aquifers, calcium and magnesium in bottled mineral and spring waters, and the significance of calcium and magnesium in waters for human health.

"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."
