Metals And Bacteria Partitioning To Various Size Particles In Ballona Creek Storm Water Runoff, John Dorsey, Jeffrey S. Brown, Eric D. Stein, Drew Ackerman, Jessica Lyon, Patrick M. Carter

Civil and Environmental Engineering Faculty Works

Many storm water best management practice (BMP) devices function primarily by capturing particulate matter to take advantage of the well-documented association between storm water particles and pollutants. The hydrodynamic separation or settling methods used by most BMP devices are most effective at capturing medium to large particles; however, these may not be the most predominant particles associated with urban runoff. The present study examined particle size distribution in storm water runoff from an urban watershed in southern California and investigated the pollutant-particle associations of metals (Cu, Pb, Ni, and Zn) and bacteria (enterococci and Escherichia coli). During small storm events …
