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.4.4 EQUILIBRIUM CALCULATIONS WITH PHREEQC Manual calculations are useful to gain a basic understanding of ... to try things out and to gain an understanding how concentrations are affected by chemical processes and transport. ... To do a spe- ciation calculation, we use the keyword SOLUTION followed by the water composition, and PHREEQC ... 4.4.2 The PHREEQC database The database of PHREEQC contains the Equilibrium calculations with PHREEQC 135 LXII LXIII.
