An application of geochemical modeling to environmental problems, illustrated with case studies of real-world environmental investigations.Geochemical modeling is a powerful tool for characterizing environmental site contaminations and predicting environmental impacts. This book discusses the application of geochemical models to environmental practice and studies, through the use of numerous case studies of real-world environmental problems. It will serve as an advanced textbook for courses in environmental geochemistry, and as an indispensable reference for professional hydrogeologists, geochemists, engineers, and regulators, working within the environmental sphere. Support material for the book, including program codes, input files and exercise problems, is also available on the Internet.Geochemical modeling is a powerful tool for characterizing environmental site contaminations and predicting environmental impacts.

In each example the authors clearly define the environmental threat in question; explain how geochemical modeling may help solve the problem posed; and advise the reader how to prepare input files for geochemical modeling codes and interpret the results in terms ofl3P
