Priyanka Pathak, Khushboo Kumari, Aesha Bodawala


Management of solid wastes is a major challenge these days for the planners, administrators, engineers. Solid wastes are generated in tones and need to be collected, transported and finally disposed off. These operations should be carried out properly and also we have to make sure that it does not become too expensive or it also does not cause any harm to the environment. In developing countries, it is common to find large heaps of garbage festering all over the city. The problem gets further complicated due to large population and the obsolete techniques employed for waste management .For disposal of solid the insanitary methods has been adopted . Waste is a serious health concern. Techniques and technologies however are available and indigenous methods can be developed for managing these wastes properly. Solid wastes are simply material at the wrong place, which can be segregated, transformed, recycled and reused with great financial and environment benefits. Water enters into a landfill site from various sources e.g. rainfall, underground water, surface runoff. Water is also squeezed out of the wastes during compaction and consolidation. The leachate so formed is highly contaminated and carries many suspended and dissolved impurities in it. This report briefs about groundwater contamination due to improper dumping of solid waste and its mitigation by construction of Sanitary Landfill.
