The main objective of this project was to develop conceptual cover system and landform designs for the waste rock dumps.

Seepage and contaminant transport modelling was conducted to determine whether the net percolation rate met the cover system performance criteria. Soil-plant-atmosphere numerical modelling was also completed to evaluate performance of various cover system designs for flat and inclined areas. The modelling was carried out on numerous configurations to assess cover system performance with respect to net percolation and the emission of radon gas.
