Bioretention cells are commonly used green infrastructure in urban stormwater management systems. They show promising performance in managing stormwater and mitigating a multitude of pollutants. In urban catchments, they have been shown to favorably reduce the ‘flashiness’ and overall volume of surface flow resulting from storm events by promotion of storage, groundwater infiltration, and evapotranspiration. Previous studies have shown highly variable phosphorus (P) removal impacts for bioretention cells, establishing a need for more comprehensive understanding of P biogeochemistry within bioretention systems to identify the processes that are responsible. In this study, a sequential extraction (SEDEX) method was used to analyze concentrations of six P fractions in filtration media samples collected from a set of 12-year-old interconnected bioretention cells in Mississauga, Ontario, Canada.
