At industrial sites, PCBs have typically been removed from stormwater using active treatment, such as chitosan-enhanced sand filtration. While effective, these approaches are expensive and energy intensive. Green infrastructure, such as lined biofiltration with engineered media, represents a cheaper and more sustainable alternative. To support design of a lined biofiltration system, we conducted a pilot study to assess the PCB removal effectiveness and hydraulics of four side-by-side test cells. We conducted the testing for 2 months, during which time runoff was continuously pumped during storm events from an existing stormwater vault to the test cells. Test cell flow rates and media permeability were continuously monitored using pressure transducers and we conducted five water quality sampling events. Results indicated that all four of the test cells removed PCBs to below detection limits during all sampling events. Hydraulic data indicated that a filtration rate of 12 inches/hour limits clogging risk. These data suggest that lined biofiltration is an effective alternative for removal of PCBs from stormwater runoff.
