A chief goal of this book is to help the reader understand controls on the chemical quality of surface and subsurface-waters, both pristine and polluted. The focus is on inorganic processes and on the chemistry of soil and ground waters, with less said about the chemistry of precipitation, surface waters, or the ocean. The book leans heavily on the principles of chemical thermodynamics and the concept of chemical equilibrium. Chemical equilibrium, whether attainable or not, represents the reference state for purposes of explaining the concentrations of aqueous species in the hydrosphere. Concepts of chemical kinetics are introduced when they are known and seem applicable.
The book is intended for students who have taken at least one course dealing with chemical thermodynamics and solution chemistry, as well as an introductory course in physical geology that includes basic mineralogy. Professionals who have absorbed equivalent prerequisite knowledge should also benefit from the book. The full book contents were designed to comprise the background reading for two, three-credit courses. Many chapters have been written in such a way that their initial sections can serve as reading for the first course, with later chapter topics to be covered in the second course.
At the end of each qhapter are study questions intended to examine a reader’s understanding of important cha ter conc pts. These can generally be answered without performing calculations. If the book is used sate ,the study questions can be considered course objectives. In each chapter the study questions followed by a collection of problems designed to illustrate the use and application of chapter materials. Detailed solutions to these problems, many of which require the use of geochemical computer models such as MINTEQA2 (Allison et al. 1991), PHREEQC (Parkhurst 1995)’+ or SOLMINEQ.88 (Kharaka et al. 1988), are available from the publisher in a companion volume to this text, titled Solutions Manual – Aqueous Environmental Geochemistry. The worked problems should be especially useful for teaching purposes.
