Brian Pecson, Ph.D., P.E.

Brian Pecson, Ph.D., P.E., uses his expertise in disinfection and pathogens to address a variety of issues in water, wastewater, and recycled water treatment. Dr. Pecson is currently engaged in a number of projects related to potable and non-potable reuse, including the newly emerging paradigms of surface water augmentation and direct potable reuse. Work in this area includes the development of public health criteria for potable reuse, and the design, evaluation, and testing of reuse technologies that can reliably protect the public from both chemical contaminants and pathogenic microorganisms. Through these projects, Dr. Pecson is working with the California Division of Drinking Water to advance and expand options for the design, implementation, and permitting of innovative potable reuse systems. Dr. Pecson also has interest in residuals management, including brine streams, industrial wastes, and sludges, and how design decisions affect the carbon footprint of treatment facilities. 

Dr. Pecson has an M.S. and Ph.D. in Civil and Environmental Engineering from the University of California at Berkeley, and a B.S. and B.A. from the University of Notre Dame. Dr. Pecson is a registered engineer in the state of California with over 15 years of experience. He has authored 12 research papers on topics ranging from pathogen disinfection to public health protection.
