PThis text offers a practical introduction to a wide range of environmental topics, focusing primarily on water and wastewater, solid and hazardous waste, and air and noise pollution control. It emphasizes fundamental concepts and basic applications so that students with little or no experience in biology, chemistry, geology, and hydraulics can comprehend this book./PH3IKey features:/I/H3ULLIclear, easy-to-read style/LILIpresentation of mathematical topics at a relatively basic level/LILIhundreds of example problems, diagrams, and photographs/LILInumerous chapter review questions and practice problems/LILIutilizes both SO metric and U.S. customary units/LILInew appendix containing a basic math review/LI/ULPIBasic Environmental Technology/Ioffers 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./PPThe 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.
