Stormwater exiting roadways contains elevated levels of several metals, including antimony, chromium, copper, molybdenum, and zinc as well as heavy extractable petroleum hydrocarbons. Best management practices for stormwater treatment include the development of engineered wetland systems, such as the Lost Lagoon engineered wetland located within
Stanley Park, Vancouver. KWL, a consulting engineering firm, has partnered with researchers at the University of British Columbia on this project to address challenges it faces with implementing these systems, as traditional water quality monitoring does not provide a reliable verification that the wetlands are meeting design objectives. Using the Lost Lagoon stormwater treatment wetland as a study site, this project will provide proof of concept results that will inform the development of a DNA-based genomics tool to allow KWL to monitor and validate the performance of stormwater treatment systems.
