The rapid growth of population accompanied by industrialization and urbanization has resulted in the increased demand for potable water. groundwater is being depleted day by day both in terms of quantity and quality. There is a need to protect the groundwater from these contaminations by industries. Industries dump the solid waste residues in a secured landfill site near the industry. A common problem of the storage of the wastes in the landfill site is the potential contamination of groundwater through leaching of hazardous waste into the groundwater by means of percolation. The quantity of leachate percolating into the landfill depends on various factors such as climatic conditions, geology and hydrogeology and amount of external water entering into the secured landfill site. The chemical quality of leachate depends upon many factors such as original nature of buried waste materials and composition of waste materials as well as conditions prevailing at the secured landfill site. The present study stresses on the need of developing a groundwater flow and contaminant transport model to understand the movement of contaminant from landfill site in groundwater. The contaminant movement will be predicted for the future years to understand the contamination state over the coming years which will help the decision makers in taking important groundwater management decisions.
