Introduction to Environmental Engineering, 4/e contains the essential science and engineering principles needed for introductory courses and used as the basis for more advanced courses in environmental engineering.

Updated with latest EPA regulations, Davis and Cornwell apply the concepts of sustainability and materials and energy balance as a means of understanding and solving environmental engineering issues. With 650 end-of-chapter problems, as well as provocative discussion questions, and a helpful list of review items found at the end of each chapter, the text is both a comprehensible and comprehensive tool for any environmental engineering course.

Standards and Laws are the most current and up-to-date for an environmental engineering text....

Principles of Environmental Engineering is intended for a course in introductory environmental engineering for sophomore- or junior-level students. This text provides a background in fundamental science and engineering principles of environmental engineering for students who may or may not become environmental engineers.

Principles places more emphasis on scientific principles, ethics, and safety, and focuses less on engineering design. The text exposes students to a broad range of environmental topics—including risk management, water quality an treatment, air pollution, hazardous waste, solid waste, and ionizing radiation as well as discussion of relevant regulations and practices.

The book also uses mass and energy balance as a tool for understanding environmental processes and solving environmetnal engineering problems.

This new edition includes an optional chapter on Biology as well as a thorough updating of environmental standards and a discussion of how those standards are created....
