Preface
For the past fifteen years I have been involved in educating undergraduate and graduate students in the field of soil/water chemistry. Early in my teaching/research career students in the colleges of agriculture in the field of soils had primarily a farming background. With the passing of time, however, this type of student declined dramatically in numbers and most universities and Colleges across the country established environmental science units in some form or another. Some of these units represented reorganization of Soil Science Departments, Forestry Departments, etc., while others represented independent Environmental or Natural Resources Departments. Similar reorganization took place or is currently taking place in Geology and Engineering schools. This field reorganization created a need for new textbooks with new emphasis in examining soil and water as natural resources. In my view, as of now we have not succeeded in introducing an appropriate textbook on the subject of soil and water chemistry to cover the needs of this new type of student.
This book is designed to serve as a beginning Textbook for college seniors and beginning graduate students in environmental sciences tailored specifically for the disciplines of Soil Science, Environmental Science, Agricultural Engineering, Environmental Engineering and Environmental Geology.
The textbook contains reviews of all the necessary fundamental principles of chemistry required for understanding soil/water chemistry/quality and soil/water treatments of chemically polluted soils and waters, e.g., heavy-metal contaminated soil/water, acid drainage, revegetation of disturbed lands, restoration of sodic soils and brackish waters, etc. The purpose of the book is to educate college seniors and beginning graduate students in the toxicity, chemistry and control of pollutants in the soil/water environment and on application of such knowledge to environmental restoration. Special emphasis is placed at the educational level at which the book is written so that it is understood by seniors and beginning graduate students majoring in environmental science.
The book consists of two major sections, principles and application. Each section covers several major subject areas. The principles section covers the subject areas of I. WATER CHEMISTRY AND MINERAL SOLUBILITY, II. SOIL MINERALS AND SURFACE CHEMICAL PROPERTIES and III. ELECTROCHEMISTRY AND KINETICS. The application section covers the subject areas of IV. AGRICULTURAL CHEMICAL POLLUTION AND ITS CONTROL, V. COLLOIDS AND TRANSPORT PROCESSES IN SOILS, VI. LAND DISTURBANCE POLLUTION AND ITS CONTROL, VII. USES OF ANTHROPOGENIC/INDUSTRIAL BYPRODUCTS and VIII. SOIL AND WATER: QUALITY AND TREATMENT TECHNOLOGIES. Each subject area contains one to three chapters.
