Deepali Marghade11 2Department of Geology, Rashtrasant Tukadoji Maharaj Nagpur University, Nagpur, India ABSTRACT The explosive growth in population and sustained drive for economic progress and development over the last couple of decades has resulted in remarkable increase in quantity of municipal solid wastes generation in Nagpur. Land filling is the most popular way for municipal solid waste disposal. Leachate generated from landfills is becoming a great threat to the regional aquifers as it contains high concentrations of toxic substances. This study aimed to assess the quality of groundwater resources serving the communities situated in the vicinity of Bhandewadi landfill of Nagpur city. Groundwater samples were collected, analyzed and characterized. Analytical results showed a measurable impact of the landfill on groundwater quality. Elevated levels of Na+, NO3-, Cl- and heavy metals, such as Mn and Fe, were detected at measurable levels in groundwater. The ionic ratio plots suggest that the silicate weathering and anthropogenic activities are dominant factors that determine the major ionic composition in the study area. The Na-Cl water type is associated with high nitrate pollution. Majority of the samples are not suitable for domestic purposes and far elevated compared to drinking water standards. Continuous water quality monitoring is suggested to effectively study the impact of landfill sites on the environment and human health. Adequate buffer zone between the landfill site and the adjacent property line should be maintained, before locating a new landfill site. Reference: Marghade, D., D.B. Malpe, and A.B. Zade. 2010.
