Textbook in PDF format Numerous new technologies and approaches have been developed since the first publication of Fundamentals of Environmental Engineering. This newly revised and updated edition continues to have a focus on fundamental concepts and on mass and energy material balances, but it eliminates some of the least-used concepts and allows space for new and more common aspects of environmental engineering practice. Expanding its use at the junior level, the author explains current environmental engineering issues including emerging contaminants and management of air, water, soil, and sediment pollution
