ABSTRACT
Leachate generated from municipal solid waste landfill site affects the groundwater quality in the adjacent areas through percolation in the subsoil. In this study, Aggregate Index method is applied to determine the quality of groundwater around a municipal solid waste dumping site. As the aggregate index is an increasing function of the distance from the landfill site, the groundwater quality improves as one move away from the landfill site. Aggregate index decreases with increase in time. Thus, water quality goes down with time. It may be due to the reason that with the passage of time the solid waste material gets degraded and the waste constituents percolate down along with rainwater thereby polluting groundwater. Hence, some remedial measures are required to prevent further contamination of groundwater in the vicinity.

Keywords :Leachate, landfill, municipal solid waste, groundwater, aggregate index.
