Davis and Cornwell's Introduction to Environmental Engineering is one of the most comprehensive resources on the multiple aspects of environmental engineering, from solid waste disposal to air and noise pollution. Pedagogically oriented toward engineers, the text places a much-needed emphasis on fundamental concepts, definitions, problem-solving, and design, while providing numerous homework problems and discussion questions in each chapter. The 4th edition features completely up-to-date coverage of environmental laws, regulations, and standards, as well as the addition of a new chapter on materials and energy balances, and end of chapter computer application problems. A discussion on environmental ethics complete with case studies and homework problems presents the legal framework that governs environmental engineering design.
