Professor and Canada Research Chair, University of Waterloo
Professor Mark R. Servos is the Canada Research Chair in Water Quality Protection in the Department of Biology, University of Waterloo. He is an internationally recognized researcher in the area of environmental assessment and risk of emerging contaminants of concern, including endocrine disruptors, pharmaceuticals and personal care products. Dr. Servos and his group have conducted numerous studies examining the fate, effects and remediation of emerging contaminants in a variety of sectors including extensive studies on municipal wastewaters. His research also develops innovative technologies to remove these contaminants from water and tests remedial actions to minimize their risks. He is improving frameworks to assess and remediate multiple stressors and their cumulative effects across watersheds.
Professor Servos worked as a research scientist with the Department of Fisheries and Oceans (Great Lakes Laboratory for Fisheries and Aquatic Sciences, 1988-1996) and Project Chief with Environment Canada (National Water Research Institute) (1996-2003) before he joined the University of Waterloo as a Professor of Biology in 2003. Until 2011 he served as Scientific Director of the Canadian Water Network, a national Network of Centres of Excellence, focused on innovation in the water sector. He plays an active role in international scientific societies and served as President of both the International Association of Great Lakes Research and the Society of Environmental Toxicology and Chemistry. He has led or participated in many national and international workshops, projects, committees and panels that address the risks and management of contaminants in the environment and water systems.

He is a Fellow of the Society of Environmental Toxicology and Chemistry and was recently recognized with Stephen J. Klaine Environmental Education Award for his commitment to innovative interdisciplinary teaching and outreach.
Professor and Canada Research Chair on Water Quality Modeling, Université Laval
Peter Vanrolleghem is a bio-engineer from Ghent University (Belgium), where he specialized in industrial microbiology. His PhD from the same university was a modelling methodology study for wastewater treatment. After 9 years as a professor at this university, dealing with a variety of bioprocess modelling studies, he immigrated to Canada in 2006 as holder of the Canada Research Chair in Water Quality Modelling. Most of his research has focused on the monitoring and modelling of water quality in the integrated urban wastewater system, starting from the drop coming out of a cloud or the tap, traveling through storm and combined sewer systems and the water resource recovery facility, until the impacts on lakes and rivers. Starting in the mid-90s, he been particularly interested in modelling and predicting the fate of (down-the-drain) chemicals of emerging concern and pollution associated with suspended solids.
As a modelling methodology expert with considerable field study experience, he has insights in experimental design, setting up measurement campaigns, installing sensors and data treatment methods in view of high quality modelling. The new models he develops are so-called phenomenological: they are based on bio-physicochemical mechanisms, but don’t go into the full details so as to make them manageable in terms of data needs, and keep them focused on solving the problem at hand.
In terms of the COVID-19 wastewater-based epidemiology, it is worth mentioning that Peter has collaborated with Christoph Ort (Eawag) on the back-calculation issues due to in-sewer biodegradation of a variety of drugs (ES&T, 50, 13351). He also has a good understanding of measurement and modelling uncertainties in decision-making. With the Danish Technical University, an extensive model library was developed for dynamic priority pollutant fate throughout the overall wastewater system. This model library covers most processes that may affect the fate of SARS-CoV-2 as it travels through the sewer system.
Professor and Chair of Chemical Engineering, McGill University
Dr. Yargeau is a Professor and Chair of the Department of Chemical Engineering at McGill. Her research focuses on the treatment of wastewater and the fate and effects of contaminants in the environment and engineered systems. She has contributed to creating awareness about the presence and impact of trace contaminants in water and to the development of improved wastewater treatment technologies for the protection of our water resources. She has been doing research on wastewater-based epidemiology (WBE) since 2008 and joined the European group SCORE in 2014 to contribute to the development and deployment of the WBE approach. She’s also worked in close collaboration with Statistics Canada for the design and implementation of the pan Canadian pilot project on wastewater-based monitoring of drug consumption in the context of the legalization of cannabis in October 2018.
