Building on the success of its 1993 predecessor this second edition of Geochemistry Groundwater and Pollution has been thoroughly re written updated and extended to provide a complete and authoritative account of modern hydrogeochemistry Offering a quantitative approach to the study of groundwater quality and the interaction of water minerals gases pollutants and microbes this book shows how physical and chemical theory can be applied to explain observed water qualities and variations over space and time Integral to the presentation geochemical modelling using PHREEQC code is demonstrated with step by step instructions for calculating and simulating field and laboratory data Numerous figures and tables illustrate the theory while worked examples including calculations and theoretical explanations assist the reader in gaining a deeper understanding of the concepts involved A crucial read for students of hydrogeology geochemistry and civil engineering professionals in the water sciences will also find inspiration in the practical examples and modeling templates
