Groundwater Geochemistry and Isotopes provides the theoretical understanding and interpretive methods for the use of geochemistry and isotopes in the practice of hydrogeology. This text simplifies the basics of aqueous geochemistry and the complementary use of environmental isotopes, using case studies to illustrate principles. This second edition includes new methods and case studies since the first publication. Accessible to consultants and practitioners as well as undergraduates and graduates, this new edition is supported by a workbook of example problems and test problems with solutions in a separate document for instructors. Additional material in the workbook is included on groundwater sampling, field measurements, testing alkalinity and routine analytical methods. Covers the basics of solutes, gases, and isotopes in water, and concentration-activity relationships and reactions. Describes tracing the water cycle, weathering, and the geochemical evolution of water quality. Explores dating groundwater as young as a few years to over hundreds of millions of years. Uses case studies to demonstrate the application of geochemistry and isotopes for contaminated groundwaters. A Groundwater Geochemistry and Isotopes workbook, including example problems, test questions with solutions and sampling and analysis guide, is freely available to instructors by request from idclark@uottawa.ca and at the website for this textbook at the link: www.routledge.com/9781032405933.
