Erik Rosenfeldt Named Director of Drinking Water Process Technology
(RALEIGH, NC – September 17, 2015) – Hazen and Sawyer has named Erik Rosenfeldt, PhD, PE, the firm’s Director of Drinking Water Process Technology.
Dr. Rosenfeldt specializes in treatment and prevention strategies for traditional and emerging contaminants in drinking water and reuse applications, including endocrine disruptors, pharmaceuticals and personal care products, pathogens, algal toxins, groundwater pollutants, and traditional and emerging DBPs like THMs, HAAs, and nitrosamines. Dr. Rosenfeldt has worked with many others in the firm’s Drinking Water Practice Group and through collaborations outside the firm to lead efforts in developing Hazen’s expertise in several key process and water quality areas, including ozone, advanced oxidation, aeration for THM reduction, hybrid GAC implementation strategies, drinking water biofiltration optimization, and holistic control of algae, cyanotoxins, and taste and odor.
“In the last few years, Erik has been at the forefront of several issues facing drinking water utilities, including DBPs and algal toxin mitigation,” said Charlie Hocking, President of Hazen and Sawyer. “In this new role, he can apply his expertise to assist utilities nationwide.”
“Erik is a nationally recognized expert in drinking water quality and in physical chemical treatment processes. His previous experience in academics gives him insight that many others in the consulting field do not have. This new position will allow him to continue his leadership in the drinking water field,” added William Becker, Hazen’s Corporate Drinking Water Practice Leader.
Dr. Rosenfeldt has been with the firm for over five years, and has served as technical lead and/or project manager on numerous research, evaluation, and design projects. He also serves the drinking water industry as a member of the AWWA Organic Contaminants Research Committee, a member of the AWWA Technical Advisory Workgroups on Disinfection Byproducts and Cyanotoxins, chair of the Virginia AWWA Drinking Water Quality and Research Committee, an invited member of an Eastern Virginia Groundwater Management Commission work group and has served on the Board and Executive Operating Committee of the International Ultraviolet Association. Dr. Rosenfeldt also volunteers with the Community Engineering Corps, with the mission to help underserved communities in the United States meet their infrastructure needs.
