| Abstract: | "Bioretention cells are a stormwater management technology intended to reduce the quantity of water entering receiving bodies. They are also used to reduce contaminant releases, but their performance is unclear for hydrophilic persistent and mobile organic compounds (PMOCs). We developed a novel eight-compartment one-dimensional (1D) multimedia model of a bioretention cell ('Bioretention Blues') and applied it to a spike and recovery experiment conducted on a system near Toronto, Canada, involving PMOC benzotriazole and four organophosphate esters (OPEs). Compounds with (log?ª+D(OC)) (organic carbon-water distribution coefficients) < approximately 2.7 advected through the system, resulting in infiltration or underdrain flow. Compounds with log?ª+D(OC) > 3.8 were mostly sorbed to the soil, where subsequent fate depended on transformation. For compounds with 2.7 |
