Managing Reservoirs and Drinking Water Treatment Plants for Optimal Water Quality

View the workshop agenda.

Utilities that rely on reservoirs for their water supplies face unique regulatory and aesthetic water quality challenges. Managing these challenges at the source is the first step in drinking water treatment. This workshop will focus on sampling and monitoring to evaluate the water quality characteristics in reservoirs as well as the operational issues and solutions associated with reservoirs and water treatment facilities.

Registration begins at 9:00 am, Workshop begins 9:30 am and ends at 12:30 pm. Lunch will be provided and a tour of the Plant will be available after lunch.

The agenda features a keynote address by Dr. G. Dennis Cooke, Kent State University Professor Emeritus and author of the book “Restoration and Management of Lakes and Reservoirs.”


Reservoir Management for Potable Water Quality – First Steps – G. Dennis Cooke
Dr. Dennis Cooke earned his Ph.D. at the University of Iowa in 1965. After a post-doctoral at the Institute of Ecology at the University of Georgia, he joined the faculty at Kent State University, where he taught for 36 years. He is the first author of 5 books, including “ Reservoir Management for Water Quality and THM Precursor Control” (AWWARF) and “Restoration and Management of Lakes and Reservoir (Taylor and Francis). Dr. Cooke was a pioneer in the development of our understanding of eutrophication and associated lake restoration methodology, served as the inaugural president of the North American Lake Management Society, and helped develop several lake management techniques, including alum application.

Reservoir Water Quality Challenges – An Overview – Ben Stanford
Dr. Ben Stanford is the Director of Applied Research at Hazen and Sawyer. Dr. Stanford joined Hazen and Sawyer in 2009 from the Southern Nevada Water Authority in Las Vegas, NV, where he worked with Shane Snyder on a variety of drinking water, wastewater, and reuse projects. Dr. Stanford’s current work ranges from understanding the impacts of climate change on water quality to investigating advanced treatment technologies for water treatment and water reuse, among others.

Reservoir Sampling and Monitoring – Developing a Plan – Erik Rosenfeldt
Dr. Erik Rosenfeldt joined Hazen and Sawyer from the University of Massachusetts, where he was an assistant professor in the Environmental Engineering and Water Resources Program in the department of Civil and Environmental Engineering. Dr. Rosenfeldt’s work focuses on understanding advanced physical and chemical treatment technologies for emerging contaminants in drinking water and water reuse applications including sorption techniques, UV, ozone, and advanced oxidation technologies.

Improving Reservoir Water Quality for Treatment Plant Operations – Josh Weiss
Dr. Weiss specializes in water resources management and source water quality. He has extensive expertise in water supply planning and real-time management of reservoir systems to meet multiple objectives. He is also a leading expert in the use of riverbank filtration to improve source water quality. He holds a BS in Civil Engineering from Georgia Tech and an MS and PhD in Environmental Engineering from Johns Hopkins University.

Optimizing Water Plant Operations for Treating Difficult Reservoir Supplies – Jim DeWolfe
Jim DeWolfe serves as the Water Treatment Operations Leader for Hazen and Sawyer. For over 20 years he has worked with municipal clients throughout the United States evaluate and optimize treatment facilities. He specializes in developing strategies to address unique challenges induced by source water changes. These changes include algae blooms, high turbidity, low alkalinity, diurnal and seasonal changes, and taste and odor control.
