Municipal Solid Waste and its Relation with Groundwater Contamination in Lahore, Pakistan

Solid waste dumping sites always pose serious environmental problems on air, soil, surface water and groundwater. Landfill leachate contains thousands of complex components and become part of groundwater after infiltration. Vicinity communities are comparatively more affected through hazard activities. Generally, it is regarded as global issue but problems are more sever in developing countries due to mismanagement and lack of related facilities. The present study investigated the landfills effects on groundwater system in Lahore city, Pakistan. Sixteen points were selected for groundwater sampling in the study area during 2010 and were analyzed for selected twelve parameters. Samples were collected to and far from three dumping sites and found in mostly samples contains high pollutants concentration than Pakistan Standards and Quality Control Authority (PSQCA, 2004) and arsenic concentration over World Health Organization (WHO) drinking water criteria. Dumping sites impacts are in result of changing groundwater chemistry, waterborne diseases and other environmental issues. Numerous studies have been conducted but still a comprehensive research needs with boarder aspects to preserve and protect groundwater resources.
