SIMULATION AND MODELLING OF THE FATE AND TRANSPORT OF CHEMICAL WARFARE AGENTS IN LABORATORYSCALE LANDFILLS

A terrorist attack could result in the generation of large quantities of contaminated building debris that requires disposal. This debris could be contaminated with chemical and/or biological contaminants. The development of plans for the safe disposal of large quantities of contaminated debris requires information on the behavior of such debris in landfills. This information is required to insure that the cleanup from a catastrophic event can proceed without delays attributable to concerns over the safety of a disposal alternative.

A terrorist attack could result in the generation of large quantities of contaminated building debris that requires disposal. This debris could be contaminated with chemical and/or biological contaminants. The development of plans for the safe disposal of large quantities of contaminated debris requires information on the behavior of such debris in landfills. The overall objective of this research is to develop and experimentally validate a model to describe the transport of chemical warfare agents in a simulated landfill. The fate and transport of organic chemicals in landfills is governed by several processes including volatilization, sorption/desorption, biodegradation, abiotic hydrolysis and the association of chemicals with humic matter. Initial work will be conducted in batch systems to study each fate process in isolation. Thereafter, work will be conducted in columns in which all fate processes, landfill gas production, and water flux are influencing contaminant behavior concurrently.

METAL SPECIATION IN NINE FRENCH LANDFILL LEACHATES
© IWWG International Waste Working Group (10/2007)
Several heavy metals or metalloids, that may be present in landfill leachates, are considered as priority pollutants for groundwater resources (for example lead, cadmium, nickel; OJEC, 2001). While the fate and transport of such elements are largely influenced by chemical speciation reactions, landfill risk assessments generally adopt a simplified “Kd” approach which assumes steady-state liquid-solid partition between the liquid and solid phases. Such simplification may result in a severe overestimation of long-term environmental or health impact. Speciation reactions such as precipitation or co-precipitation participate in the natural attenuation of landfill leachate and help explain why heavy metals are rarely detected in groundwater at significant distances from landfills (Christensen et al., 2001).
