This powerpoint presentation begins by providing background information on nanoparticles, risks posed by nanomaterials, and their impacts on water treatment. Nanoparticle aggregation, mobility in porous media, filtrate composition, and SEM imagery of effluent materials are outlined with conclusions being that: nanoparticles are present in filtrate fromconventional granular media filters atwater treatment systems;nanoparticles do aggregate underconditions typical of many aqueoussystemsdependent on surface chemistry, unknown aggregation efficiency, andgeneration of nanoparticles following filtration; and, nanoparticles are not inherently moremobile in porous media. Includes tables, figures.
