| This document was prepared by Julia Kane Africa during an internship with the U.S. Environmental Protection Agency, sponsored by the Environmental Careers Organization. This paper focuses on the treatment of high molecular weight (HMW) polycyclic aromatic hydrocarbons (PAH), and the potential for bioswales and rain gardens to mitigate contamination in urban settings is discussed. This paper is designed to serve as a point of reference for planners, public officials, and ecologists interested in exploring what contribution biofiltration and phytoremediation can make to polycyclic aromatic hydrocarbon mitigation of urban run-off. |
