Robert Gillham is one of Waterloo's most recognised research scientists in the field of groundwater remediation. His invention of the reactive permeable barrier is used worldwide today.
John Spoelstra explores the impact of human activities and climate change on water quality in a variety of landscapes including urbanized watersheds, forested catchments and wetlands.
He uses novel geochemical tools such as artificial sweeteners and stable isotopes to trace wastewater and other human impacts on watersheds across Canada.
Since joining the University of Waterloo in 1971, there is no doubt John Cherry has had a profound and sustained impact internationally on the field of hydrogeology.
A world expert on quantitative and integrated hydrosystem modelling, Ed Sudicky is a Fellow of both the Royal Society of Canada and the Canadian Academy of Engineering.
Will Robertson studies the physical hydrogeology and geochemistry of contaminated groundwater.
His current research interests include assessment of groundwater impacts from septic systems and mine tailings, innovative remediation techniques, groundwater age dating tools.
Alan Morgan was an international expert in Quarternary geology, mapping and studying past permafrost structures in Britain and Canada. He also specialized in Quarternary entomology, the study of fossilised beetles as a way to reconstruct past climate conditions.
Jim Barker's research focuses on groundwater contamination by organic chemicals, especially petroleum hydrocarbons and industrial chemicals.
A faculty member at the University of Waterloo since 1979, he retired in 2010.
