Basic Environmental Technology offers a pragmatic introduction to the topics of municipal water supply, waste management, and pollution control. The book is designed primarily for use by students in civil/construction technology programs and related disciplines in community colleges and technical institutes. It can also be useful in baccalaureate engineering and technology programs when a practical but elementary course of study is desired, or for independent study by individuals who wish to explore the rudiments of environmental quality control and public health protection. Experienced technicians, engineers, scientists, and others in different disciplines who may become involved in environmental work for the first time will also find this book of value as an initial reference.
The qualities that continue to distinguish this book in its fourth edition are its clear, easy-to-read style and its logical and systematic treatment of the subject. Since the field of environmental technology is multidisciplinary and very broad in scope, review or primer sections are included so that readers with little or no experience in biology, chemistry, geology, and hydraulics can comprehend and use the book. Mathematical topics are presented at a relatively basic level; to understand all the numerical examples in the book, some knowledge of algebra and geometry will be useful.
Hundreds of example problems, diagrams, and photographs are used throughout to illustrate and clarify important topics. Numerous review questions and practice problems follow each chapter; answers to the practice problems are presented in Appendix G. SI metric as well as U.S. Customary units are used,since students and practitioners in the United States must still be familiar with both systems. A separate Instructor's Manual is available with worked-out solutions for the end-of-chapter practice problems and with supplementary problems that can be used for additional homework assignments or test questions.
The first chapter of the book provides an overview of environmental technology, including elements of public health, ecology, geology, and soils. The next nine chapters focus on water and wastewater topics, including hydraulics and hydrology, water quality and water pollution, drinking water treatment and distribution, sewage collection, sewage treatment and disposal, and stormwater management. Municipal solid waste, hazardous waste, air pollution, and noise pollution are covered in Chapters 11 through 14. Finally, appendixes covering environmental impact statements and audits; the employment of technicians; technologists, and engineers; basic mathematics; units and conversions; selected references; an extensive glossary; and a color photo insert (at the back of the book) are included.
There is more than ample material in this book for a typical one-semester course. Chapters 1 through 10 should suffice for introductory courses that focus mostly on water and wastewater topics. In courses where air quality, solid and hazardous waste, and noise pollution are also part of the syllabus, the instructor will probably find it necessary to be selective in coverage of topics from the first ten chapters to allow time for discussion and study of the last four chapters. In such circumstances, less time could be spent on the quantitative parts of the text (for example, hydraulics) and more time spent on the descriptive and qualitative aspects of environmental technology. Another option could be to focus in lectures on the first ten chapters for most of the semester, and allow students to select topics of special interest to them from those among the last four chapters for a term paper and/or oral presentation to the whole class. In this way, students get some exposure to those topics as well as practice in communication skills.
In this fourth edition, the text has been updated where necessary and some new topics have been added. These topics include nonuniform open channel flow, the rainfall severity index, mass balance, sewer plan and profile details, Geographic Information System (GIB) applications, description of software applications such as SPINET and HydroCAD, best management practices for stormwater quality control, and new water/wastewater treatment technologies. The book now includes a primer of basic mathematics as well as an expanded discussion of units and unit conversions in Appendix C. The number of case studies has been increased by about 50 percent, the number of relevant Web sites has been increased by about 30 percent, and many new terms have been added to the glossary in Appendix E.
This textbook addresses a wide range of environmental subjects. Every effort has been made to maintain a balance between thoroughness and practicality in covering the material to ensure that the book will continue to be a useful learning tool for students. The topics included here are covered in greater depth and detail in other, more narrowly specialized and advanced texts; they are presented here in a form that is more readily accessible to undergraduates and others who may have occasion to use the book. It is hoped that this book will motivate as well as prepare readers to study the discipline of environmental engineering or technology at a more advanced level.
