AWS Topical Collections

AWWA Water Science Topical Collections

AWWA Water Science (AWS) is an interdisciplinary journal that features original, peer-reviewed research on the science, engineering, and social aspects of water.

AWWA Water Science topical collections are collections of articles on similar topics that fall under the guidance of AWS. Although review papers can also be part of a special collection, it is expected that the majority of articles published as a special collection will consist of new and previously un-reviewed material.




Topical Collection on Potable Reuse  reuse-icon

Water reuse is simply the use of water after it’s already been used for another purpose. Though the practice of water reuse has occurred historically across the globe, factors such as climate change and growing population (among others) have increased demands on traditional water systems so that more communities are now considering reuse, with particular interest in reuse for potable purposes. These challenges have raised many important questions about how to adapt technology and institutional structures to facilitate potable reuse. The purpose of this topical collection in AWWA Water Science is to capture the present state of the science on potable water reuse.

With this topical collection, we hope to provide a forum for improving our understanding of the challenges and solutions related to potable reuse. This collection aims to identify gaps in our knowledge and to chart a course for future water reuse research. Ultimately, we want to advance our understanding of water reuse issues and to catalyze exchange of data, ideas, approaches, methods, and solutions through an interdisciplinary approach. In addition to general research topics related to water reuse, there will be topics that include:

  • Source water management 
  • Reuse system operations 
  • Pathogen detection and treatment 
  • Treatment for trace organic chemicals 
  • Water quality monitoring 
  • Regulatory requirements and compliance 
  • Communications and outreach 
  • Socioeconomic aspects of water reuse

Kerry Howe, Guest Editor

Kerry has over 30 years of experience in the water treatment industry, with work spanning both the university and professional realms. His primary research focus is on the use of membrane processes in water and wastewater applications. His work includes focus on removal of contaminants of emerging concern using reverse osmosis and ozone/biofiltration for potable reuse. He also focuses on selective recovery and beneficial use of minerals from desalination concentrate; increasing water recovery in reverse osmosis by minimizing scaling; and fouling of microfiltration, ultrafiltration, and reverse osmosis membranes. 

Kerry earned his B.S. at the University of Wisconsin-Madison, his M.S. at University of Texas at Austin, and his Ph.D. at the University of Illinois at Urbana-Champaign. He is presently a professor and the director at the Center for Water & the Environment at the University of New Mexico.


Brent Alspach, Associate Guest Editor

Brent has over two decades of experience in potable and potable reuse water treatment. He is an internationally recognized authority on membrane filtration and desalination processes, co-authoring the USEPA Membrane Filtration Guidance Manual and contributing to five membrane themed AWWA Manuals of Practice. He has also contributed to the USEPA Water Reuse Action Plan and Chaired/Co-Chaired the AWWA International Symposium on Potable Reuse in 2016, 2018, and 2020. His current work is focused on PFAS treatment, enhanced recovery of NF/RO systems, and the conversion of stormwater for potable reuse. 

Brent earned both his B.S. and M.S. in Civil & Environmental Engineering from Cornell University. He joined Arcadis in 1997 and presently serves the company’s director of applied research.


Christopher Bellona, Associate Guest Editor

Chris has over 15 years of experience in potable water reuse research. His primary research focus is on the use of advanced water treatment processes for the removal of organic contaminants from various source waters. His work has included evaluating innovative membrane technologies in potable reuse treatment trains, alternative potable reuse unit treatment processes, and quantifying the fate of contaminants in membrane systems. He has worked on various research projects focusing on PFAS treatment, membrane fouling, mine water treatment, and development of innovative treatment approaches for a variety of applications. 

Chris earned his B.S. at Western Washington University, and his M.S. and Ph.D. at the Colorado School of Mines. He is presently an Assistant Professor at the Colorado School of Mines.


Julie Minton, Associate Guest Editor 

Julie Minton is the Director of Strategic Initiatives at The Water Research Foundation (formerly WateReuse and Water Environment & Reuse Foundation). Julie has been at the foundation for more than 10 years, working in different capacities in water reuse, including Director of Research and Project Management. Julie is currently the Project Director for the $4.5 million grant from the California State Water Board and responsible for fundraising to leverage this grant and expand the impact across the US and beyond. 

Julie earned her B.A. from St. Mary’s College of Maryland.


George Tchobanoglous, Associate Guest Editor 

George has more than 40 years of experience in water and wastewater treatment, and he is an international authority on wastewater treatment, management, and reuse. His research interests are in the areas of wastewater treatment, water reuse, and decentralized wastewater management. He has authored or co-authored more than 600 technical publications including 23 textbooks and 8 reference works. He has written extensively on water reuse, dating back to 1969. In 2004, he was inducted into the National Academy of Engineering. In 2017 he received two honorary Doctor of Engineering degrees from two universities in Greece. George’s work with ultraviolet radiation in the 1990s led to broader acceptance of using UV to disinfect wastewater for reuse, and his work became "the standard" U.S. resource on this topic.

George earned his B.S. degree in Civil Engineering from the University of the Pacific, his M.S. degree in sanitary engineering from the University of California at Berkeley, and his Ph.D. from Stanford University. He is currently a professor emeritus in the Department of Civil and Environmental Engineering at the University of California, Davis.

The submission window for inclusion in the topical collection is now closed.
