The diffusion and sorption characteristics of a geosynthetic clay liner (GCL) are examined for a group of volatile aromatic hydrocarbon: benzene, toluene, ethylbenzene, m & p-xylene and o-xylene (BTEX) at two different temperatures. It is shown that geotextile component of a GCL significantly contributes to the sorption of these hydrocarbons. The reduction in diffusion and sorption coefficients with decreasing temperature have opposite effects in terms of the rate of contaminant movement through a GCL however it is shown that the decrease in transport due to a reduced diffusion coefficient dominates and mass transport is reduced at lower temperature.
