A pilot study was undertaken by researchers at Fleming College in Ontario, Canada to assess the phosphorus removal performance of bioretention soil mix amended with Sorbtive Media. Five bioretention cells were constructed and filled with a soil mix comprised of sand, peat moss, and various percentages of Sorbtive Media^TM. Batches of artificial stormwater containing differing concentrations of phosphorus were used to simulate storm events on the bioretention cells. Through analysis of the influent and effluent concentrations, it was determined that the amended bioretention cells demonstrated substantial improvement in phosphorus removal. Each of the amended cells maintained removal efficiency of up to 99 % and at least 84 % for the duration of the study, even when blended into the soil mix at only 3 - 5 % volume basis.<ref>Balch G.
