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.

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.

The first book devoted entirely to the problem of nitrate risk and behaviour in groundwater, this volume includes twenty-seven papers selected from those presented during the Euromeeting of the International Association of Hydrogeologists "Nitrate in Groundwater in Europe" held in Wisla, Poland in 2002. The problems presented and discussed in Wisla covered all aspects of nitrate pollution of groundwaters globally, while the articles describing the case studies focus on groundwater in Europe. The remaining chapters examine the main chemical and physical processes which affect nitrate in groundwater, as well as describing nitrate distribution in various aquifers, seen as an essential problem areas of groundwater protection.
