Identification and Treatment of Toxicants in Highway Runoff Using Green Stormwater Infrastructure, Bioassays, and Chemical Fractionation

Project Information

Project ID:
FHWA-PROJ-18-0019
Project Abstract:

The study is to be conducted by the Washington State University, University of Washington, and NOAA fisheries.  The objectives of this research study are: to understand how roadway runoff treatment technologies work with respect to acute toxicants in runoff; and chemically characterize untreated and treated runoff samples to identify toxicants and surrogate/indicator compounds that scale with water quality improvement and may be used to assess treatment performance.

Project Outputs:

The toxicological assessments of CABS performance generally agreed with the chemical assessments. Toxicity associated with influent water samples was often but not always removed by CABS treatment. Better treatment was found for the field site than the lab system (67% removal of toxicity vs 21%). This difference may be explained by the longer length, longer HRT, and greater infiltration capacity at the field site than in the lab system which was designed primarily to test the surface treatment mechanisms of the CABS.

Project Outcomes/Impact:

Impact methodology for WSDOT in designing CABS to attain treatment goals for surface flows
