Bioretention

 Transport and Capture of Pathogens from Urban Stormwater Runoff using Bioretention

This research study began in Fall, 2005 and is sponsored by the Cooperative Institute for Coastal and Estuarine Environmental Technology.  Column and field studies will be employed to investigate E. coli transport, capture, and dieoff in bioretention media.  The capability of both traditional sand and soil layers, as well as novel engineered media layers (iron oxide-coated sand) will be systematically evaluated in laboratory studies for their capacity to capture pathogens. 

Co-Investigators on the project are Prof. Eric Seagren and Dr. Jeff Karns of the U.S. Department of Agriculture, Beltsville Agricultural Research Center.

This work is being completed by Doctoral student Lan Zhang.
