<p/><br></br><p><b> About the Book </b></p></br></br>"Groundwater known as the least contaminated source of freshwater on the Earth. It is excessively being used in different sectors for diverse purposes such as drinking, agriculture, industrial use and fish culture. Approximately 1.5 billion population is dependent on the underground source of water. Groundwater quality is greatly affected by Sub-surface geology, topography, climate change, and natural events such as earthquake, flood and landslide. This chapter presents a holistic approach about the geogenic pollutants, including their mineralogical sources, remedial measures and impact on the human health in different geographical regions of India. The geogenic pollutant is defined as the surpassing of certain thresholds regarding drinking water recommendations in sub-surface water system devoid of direct or indirect anthropogenic intervention. Longer residence time, often combined with favourable geologic conditions and mineralogy of the aquifer, leading to groundwater pollution by geogenic contaminants. The commonly known geogenic pollutants are Arsenic (As), Fluoride (F), Iodine (I), Uranium (U), Sodium (Na), Chloride (Cl), Sulphate (SO4), and trace element such as iron (Fe), Manganese (Mn), Chromium (Cr), selenium (Se) etc. As and F are widely studied geogenic pollutants in various geographical regions. The mechanism behind the As mobilization under alkaline and reducing conditions are identified as reductive dissolution of As-bearing Fe minerals, reductive desorption of As(V) and formation of readily mobile complexes. Whereas, F enrichment is affected by the solubility of F bearing minerals, restriction of groundwater conditions, and the presence of precipitating or complexing ions."--<p/><br></br><p><b> Book Synopsis </b></p></br></br><p>This book contains both practical and theoretical aspects of groundwater resources relating to geochemistry. Focusing on recent research in groundwater resources, this book helps readers to understand the hydrogeochemistry of groundwater resources. Dealing primarily with the sources of ions in groundwater, the book describes geogenic and anthropogenic input of ions into water. Different organic, inorganic and emerging contamination and salinity problems are described, along with pollution-related issues affecting groundwater. New trends in groundwater contamination remediation measures are included, which will be particularly useful to researchers working in the field of water conservation.
