ResumoThe effect of dissolved organic carbon (DOC) in landfill leachate on the transport of a hydrophobic organic compound through saturated aquifer material was investigated. Leachate DOC was found to be complex; attempts to characterize the organic matrix were not successful. Two hydrophobic compounds of environmental significance were evaluated for 1) their partitioning to DOC in leachate, and 2) the effects of leachate on their partitioning to aquifer material. Results showed that the leachate reacts with aquifer material to increase partitioning to the stationary phase and that the DOC in the landfill leachate enhances mobility of the hydrophobic compounds. The conclusion was that at present, we do not know how to predict the impact of a given leachate on a given aquifer material without experimental measurements.
