A methodology is used to identify the tradeoffs between costs and exposure risk associated with landfill leachate collection and low permeable systems. The results are useful in demonstrating the point at which additional levels of sophistication in design of a leachate/liner system do not produce significant reductions of exposure risk. The case study application to the Durham Regional landfill demonstrates that clay liner hydraulic conductivity is the parameter with the largest influence on the risk of exceedance at the point of compliance. When the underlying clay is more permeable, there is a significant merit associated with use of a QA/QC program.
