Seasonal Variation Analysis of Leachate Contamination Potential from Landfill using Leachate Pollution Index

Abstract

Co: ntaining hundreds of different chemicals, the characteristics of municipal landfill leachate vary greatly within an individual landfill over space and time. Also, leachate characteristics vary considerably from one landfill to another. For the proper and efficient operation of leachate treatment, evaluation of seasonal variation plays an important role. The contamination potential of leachate can be calculated in terms of LPI. The calculated LPI of Okhla Sanitary landfill was 62.32 and 44.14 in the summer and winter seasons respectively.
