Characterization of Leachate from Municipal Solid Waste (MSW) Landfilling Sites of Kalaburagi, Karnataka, India

The paper discusses the characteristics of leachate generated from municipal solid waste landfilling sites of Udnoor village, Kalaburagi district (Karnataka). Leachate samples were collected and analysed for various physico-chemical parameters to estimate its pollution potential. This study aims to serve as a reference for the implementation of the most suitable technique for reducing the negative environmental effects of discharge leachate. the landfilling sites of Udnoor village are engineered low lying open dumps. They have bottom liner and leachate collection system. Therefore, It has been found that leachate contains high concentrations of organic and inorganic constituents beyond the permissible limits. While, heavy metals concentration was in trace amount as the waste is domestic in nature. The data presented in this study indicated that the age of the landfill has a significant effect on leachate composition. the biodegradable fraction of organic pollutants in the leachate decreases as an outcome of the anaerobic decomposition occurring in the landfill.
