Assessment of Stabilization, Temporal Variation and Leachate Contamination Potential of Municipal Solid Waste Dumpsites in Bangalore

摘要

One of the biggest problems associated with the dumping of solid waste is managing leachate that is formed when water passes through the deposited waste. It contains products of decomposition of organic matter and soluble ions which present a potential pollution threat for the surrounding soil, surface and ground waters. The knowledge of the composition of leachate helps to ascertain the contamination potential it poses to the immediate ecosystem and also aids to design an effective treatment technology and appropriate liners to contain the leachate. In this paper, leachate pollution index has been used to quantify the contamination potential that the dumping sites pose to the environment. This study also demonstrates the influence of various stabilization stages of the dumping sites on the composition of the leachate season wise.
