Analysis of Leachate from the Municipal Solid Waste Disposal Site and Its Impact on Ground Water Quality at Lucknow Cantonment

Abstract

Abstract: Open dumping of municipal solid waste is prone to groundwater contamination because of leachate production. In this report, an attempt has been made to assess the pollution potential of leachate generated from the solid waste disposal site and its impact on aquifers in Neil line Lucknow environs, Uttar Pradesh, India. Physico-chemical parameters of leachate are determined to evaluate leachate pollution index (LPI) .A large amount of the water requirement of Lucknow City is supplied from groundwater. The quality of this groundwater was determined by taking samples from wells within the study area. The purposes of this investigation were to provide an overview of present groundwater quality. To determine spatial distribution of groundwater quality parameters such as pH, electrical conductivity, Cl− , SO4 −2 , hardness, and NO3− concentrations, and To map groundwater quality in the study area by using GIS and Geostatistics techniques. ArcGIS 9.0 and ArcGIS Geostatistical Analyst is used for generation of various thematic maps and ArcGIS Spatial analyst to produce the final groundwater quality map .
