First published in 1958, Salvato's Environmental Engineering has long been the definitive text/reference for generations of sanitation and environmental engineers. Having developed through each edition with the growth of the profession, the current book covers topics as disparate as landfills, water treatment, recreational facilities, and food handling in restaurants. Approaching its 50th year of continual publication in a rapidly changing field, the Sixth Edition has been fully reworked and reorganized into three separate, succinct volumes to adapt to a more complex and scientifically demanding field with dozens of specializations. Completely rewritten by leading experts in the field, this new edition offers succinct new case studies, new process and plant design examples, and added coverage of such subjects as urban and rural systems. Volume 1 covers water and wastewater treatment, water supply, soil and groundwater remediation and protection, and industrial waste management.

The Late Nelson L. Nemerow, PhD, was an environmental engineering and water consultant. He was a professor at the University of Miami and the former head of Environmental Engineering at Syracuse University. He published over 210 technical papers and twenty-three textbooks.

Franklin J. Agardy, PhD, is founding partner of Forensic Management Associates. As a civil engineering professor, he developed San Jose State's graduate program in sanitary engineering. He has written, coauthored, or coedited seven textbooks.

Patrick Sullivan, PhD, is founding partner of Forensic Management Associates. Prior to his forensics career, he was a senior environmental analyst at the Jet Propulsion Laboratory at the California Institute of Technology. He has written, coauthored, or coedited five textbooks.

The Late Joseph A. Salvato served as a sanitary and public health engineer consultant and assistant commissioner in the Division of Sanitary Engineering for the New York State Department of Health. He was also a Fellow of the ASCE and the APHA and adjunct associate professor at Rensselaer Polytechnic Institute.
