Abstract/Description: Colloid transport is believed to be controlled by their interactions with the porous media. The dominating forces are the electrostatic interactions that are determined by colloid surface charge density. Although it is well accepted that electrostatic interactions between colloids and the surrounding environment play a very important role in controlling colloid retention in porous media, it is not clear how pH and ionic strength impact the electrostatic forces and the subsequent colloid transport. To have a better understanding of the impact, column colloid transport experiments were conducted under variable pH and ionic strength conditions. Based on the column experiments, colloid deposition and transport were quantified using the advection-dispersion equation and linked to solution pH and ionic strength. Finally, the repulsive electrostatic interactions between the colloids and the sediments were evaluated for different pH and ionic strength conditions, which were related to colloid transport observations. Results of this research are of importance to advancing the understanding of colloid facilitated heavy metal and organic contaminant transport in the subsurface.
