Holistic approach for evaluation of landfill leachate pollution potential – From the waste to the aquifer

Leachate contamination from uncontrolled landfills is a long-lasting environmental hazard that threatens groundwater resources worldwide. We developed a holistic site-characterization approach that incorporates leachate data from the waste body, unsaturated zone, and groundwater with information on landfill geomorphology and climatic conditions. An advanced vadose-zone monitoring system was used to characterize the percolation patterns and...
