Particle transport and geochemical impact



Current research to understand the fate and transport of particulate contaminants in subsurface environments is being conducted from a variety of perspectives. The physical and chemical factors that control microbial movement, the transport of particulate organic material in aquifers, and the mobilization of radionuclides, trace metals, and hydrophobic organic contaminants by colloidal transport are among the many topics being investigated. The transport processes influencing particulates are not limited to physical hydrology; the geochemistry and microbiology of these systems fundamentally influence the transport properties. Because of the recent intense activity in these topics, the special session, “Particle Transport in the Subsurface and its Geochemical Impact,” was convened at the 1990 AGU Spring Meeting held in Baltimore, Md., May 29–June 1.
