AbstractABSTRACT Groundwater is playing an important role in human life. The rapid growth of population leads to more consumption of surface water and ground water. Groundwater has played a prominent role as a primary source of domestic water supplies and irrigation. In most of the regions, it is polluted due to natural and human activities. If groundwater gets polluted once, then the removal of pollutants is difficult. It is of great concern to remedy this hazardous and haphazard situation. The study area is Noyyal river basin (across the Orathupalayam reservoir) where, a lot of dye industries discharge their effluents without any proper treatment. In this study, the spatial variation of recovery rate of the contaminated soil is estimated. Laboratory column tests are used to determine contaminant removal rates under conditions that more closely approximate the operating conditions anticipated in the field. And various methodologies are thought-of to recover the soil to the original, non-polluted condition. In this study also estimate the travel time of a contaminant by backward transport modeling. Backward location and Travel time probabilities for a decaying contaminant in an aquifer is to be finding out by backward transport modeling.
