A large volume of information available indicates that colloid facilitates transport of contaminants in subsurface environment. The dynamic processes of colloid deposition, release and transport etc., were dominated by a number of factors, such as colloidal surface property (hydrophilic or hydrophobic), colloidal stability, chemical composition of solution, ion strength, pH, and water flow velocity, etc. The models considering different factors were developed and used to simulate colloidal transport behavior in theory or in laboratory with column experiments. In order to work out effective strategies or to develop novel remediation technologies for preventing pollution extension or remedying pollution, attentions should be paid to colloid-facilitated transport of contaminants in fields.
