The book is a step forward in the direction of hydro-geochemical analysis of selected hill springs. Further, the main focus of the study is the potability of the spring water. In many areas, springs water quality limits to supply of potable fresh water. Hence, to utilize and predict the change in spring water environments, it is necessary to understand the hydro-geochemistry. In this book, Hydro-geochemical characteristics of springs of state Uttarakhand, India have been investigated to identify the major ions that regulate hydro-geochemistry of springs.
