Water Chemistry An Introduction to the Chemistry of Natural and Engineered Aquatic Systems

Water Chemistry provides students with the tools necessary to understand the processes that control the chemical species present in waters of both natural and engineered systems. After providing basic information about water itself and the chemical composition of water in environmental systems, the text covers the necessary theory (thermodynamics, activity, and kinetics) and background material to solve problems. It emphasizes that both equilibrium and kinetic processes are important in aquatic systems. The book does not merely focus on inorganic constituents, but also on the fate and reactions of organic chemicals. The solving of quantitative equilibrium and kinetic problems using mathematical, graphical, and computational tools is emphasized throughout presentations on acid-base chemistry, complexation of metal ions, solubility of minerals, and oxidation-reduction reactions. The use of these problem-solving tools is then extended in the presentation of topics relevant to natural systems, including dissolved oxygen, nutrient chemistry, geochemical controls on chemical composition, photochemistry, and natural organic matter. The kinetics and equilibria relevant to engineered systems (e.g., chlorination and disinfection chemistry, sorption and surface chemistry) and organic contaminant chemistry are also discussed. Numerous in-chapter examples that show the application of theory and demonstrate how problems are solved using algebraic, graphical, and computer-based techniques are included. Examples are relevant to both natural waters and engineered systems.

Patrick L. Brezonik began his faculty career in environmental engineering at the University of Florida in 1966. He joined the faculty of the University of Minnesota in 1981 and is now professor emeritus (since 2010) of Civil Engineering. He also served as program director for Environmental Engineering at NSF from 2004 to 2007. His research areas are nutrient and trace metal chemistry, photochemistry, and remote sensing. William A. Arnold joined the faculty in the Department of Civil Engineering at the University of Minnesota in 1999, where he is now the Joseph T. and Rose S. Ling Professor. His research interests are in the areas of transformation, transport, and remediation of anthropogenic chemicals in the environment, including surface-mediated oxidation/reduction reactions, photochemistry, and partitioning.
