Both colloids and organic matter are ubiquitous in the environment and strongly influence water quality and public health.  However, the interaction of these materials, although qualitatively acknowledged for some time, has yet to be adequately quantified.  This laboratory-based research aims to quantify the role that natural organic matter plays in promoting/inhibiting colloidal transport through porous media.  Results have important implications in processes ranging from the efficiency of water filters to enhanced transport of colloids in contact with humic-rich waters, and the potential use of organics/colloids in enhancing contaminated site remediation.
