For one-term, undergraduate-level courses in Environmental Engineering, Pollution Control, Environmental Control, Human Environmental Systems, and Environmental Management.

Focused on current environmental problems, their causes, effects, and solutions, this text explores the basic nature of the natural systems. Using a technical (quantitative) approach -unusual for a book at the introductory level - it maintains a broad perspective that appeals to all students, but at the same time is useful to those proceeding further in environmental or sanitary engineering.
