Crozier Expands Research Program Tackling Stormwater Pollution



As concerns about water pollution continue to escalate, we are committed to improving the future of stormwater management through research partnerships with universities.

In this regard, we are thrilled to announce that Crozier & Associates has partnered with the University of Western Ontario on a research project directly related to low impact development (LID) techniques. Our research is being supported by the Ontario Centres of Excellence and the Natural Sciences and Engineering Research Council of Canada. Our team will assess water quality treatment of urban stormwater runoff in bioretention cells, both in the field and in the lab.

The research project examines how aging bioretention soil media removes contaminants when exposed to real-world stormwater compositions. Following an evaluation of existing bioretention systems, our team plans to develop new media compositions to address deficiencies noted in the field study. These compositions will be tested in the lab to compare their contaminant removal performance to those studied in the field. We anticipate that developing optimized compositions will help reduce the negative environmental impacts of stormwater contaminants on surrounding ecosystems.

“We are excited to undertake this research with the University of Western Ontario. We expect the results will help optimize bioretention system design and better inform the land development industry.”

Our research partner at Western is Dr. Clare Robinson, P.Eng., an Associate Professor and a Canada Research Chair in Water Quality. Dr. Robinson is an expert in water quality investigations related to contaminant transport and LID stormwater technologies.

Water quality sampling is occurring at six sites across the GTA and Southwestern Ontario, and will continue through early 2020.
