Leachate generation and transport from solid waste disposal at a former quarry site
The present research work simulates leachate quantity generated at a 2000 tons/day landfill facility and assesses leachate migration away from the landfill in order to control associated environmental impacts, particularly on groundwater wells down gradient of the site. The site offers unique characteristics in that it is a former quarry converted to a landfill and is planned to have refuse depths in excess of one hundred meters, making it one of the deepest in the world. The modeling estimated leachate quantity and potential percolation into the subsurface using the Hydrologic Evaluation of Landfill Performance (HELP) model. A three-dimensional, multi-phase, variably saturated model (PORFLOW) was adopted to simulate subsurface flow and contaminant transport in a fractured porous medium. While the models showed that significant potential adverse impacts were confined to the immediate vicinity of the landfill, simulation results confirmed the importance of point-of-compliance specifications in landfill performance criteria

Abstract
The present research work simulates leachate quantity generated at a 2000 tons/day landfill facility and assesses leachate migration away from the landfill in order to control associated environmental impacts, particularly on groundwater wells down gradient of the site. The site offers unique characteristics in that it is a former quarry converted to a landfill and is planned to have refuse depths in excess of one hundred meters, making it one of the deepest in the world. The modeling estimated leachate quantity and potential percolation into the subsurface using the Hydrologic Evaluation of Landfill Performance (HELP) model. A three-dimensional, multi-phase, variably saturated model (PORFLOW) was adopted to simulate subsurface flow and contaminant transport in a fractured porous medium. While the models showed that significant potential adverse impacts were confined to the immediate vicinity of the landfill, simulation results confirmed the importance of point-of-compliance specifications in landfill performance criteria
