This three-volume set is the most comprehensive and up-to-date treatment of hydrogeochemistry that is available. The first volume lays the foundation of the composition, chemistry, and testing of groundwater, while volume two covers practical applications such as mass transfer and transport. Volume three, which completes the set, is an advanced study of the environmental analysis of groundwater and its implications for the future. This third volume focuses more deeply on the analysis of groundwater and the practical applications of these analyses, which are valuable to engineers and scientists in environmental science, groundwater remediation, petroleum engineering, geology, and hydrology. Whether as a textbook or a reference work, this volume is a must-have for any library on hydrogeochemistry.
