Building on the success of its predecessor, this second edition has been thoroughly re-written and extended into a complete account of modern hydrogeochemistry. Offering a quantitative approach to studying 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. Integral to the presentation, geochemical modeling using PHREEQC code is demonstrated, with step-by-step instructions for calculating and simulating field and laboratory data....
