This volume discusses climate change impacts on groundwater quality in arid and semi-arid regions, and provides human health risk assessments due to pollution of surface and groundwater. The book presents recent trends in monitoring groundwater management and implementing pollution mitigation strategies, including practices involving remote sensing and GIS techniques, entropy water quality index, weighted arithmetic water quality index, fuzzy logic applications, and improved irrigation methods. The book also outlines hydrological processes in arid and semi-arid regions and hydrochemical properties of surface and groundwater as a necessary background for understanding how pollution impacts groundwater quality and resources, and how geographical modeling of hydrological processes can aid in human health risk assessments. The book is intended for academics, administrators, policymakers, social scientists, and professionals involved in the various aspects of climate change impact on groundwater quality, hydrological process, pollution mitigation strategies, sustainable development, and environmental planning and management.
