Bioretention Design Modifications Increase the Simulated Capture of Hydrophobic and Hydrophilic Trace Organic Compounds

Timothy F. M. Rodgers,

et al.

Abstract: Stormwater rapidly moves trace organic contaminants (TrOCs) from the built environment to the aquatic environment. Bioretention cells reduce loadings of some TrOCs, but they struggle with hydrophilic compounds. Herein, we assessed the potential to enhance TrOC removal via changes in bioretention system design by simulating the fate of seven high-priority stormwater TrOCs (e.g., PFOA, 6PPD-quinone, PAHs) with log K OC values between −1.5 and 6.74 in a bioretention cell. We evaluated eight design and management … Show more

“…3 Indeed, amended bioretention media are capable of capturing increased quantities of trace organic contaminants. 123 BioSorp beads could be incorporated into new bioretention systems or amended post-construction into existing GSI systems for bioaugmentation. BioSorp beads are designed to directly address the wicked problem of hydrophilic compounds by: (1) rapidly capturing contaminants onto the black carbon materials via chemical sorption during the rapid infiltration stages and (2) encapsulating and bioaugmenting contaminant degrading microorganisms in GSI systems.…”
