Inappropriate disposal of municipal solid waste (MSW) results in the leaching of inorganic and organic chemicals, which can contaminate the groundwater, posing great contamination risk to humans. Due to unscientific landfilling, many fast growing cities of India are falling under high risk category of groundwater pollution. This paper attempts to assess the physico-chemical characteristics of leachate due to seasonal variation in the active and closed non-engineered MSW landfill sites of Lucknow city of Uttar Pradesh, India. Leachates from different landfill sites, which are either presently active or closed, were characterized and their relationships with season were examined. Concentrations of various physicochemical parameters such as colour, turbidity, total hardness, electrical conductivity, total dissolved solids, NO3−2, NH3-N and SO4 2- were determined in leachate samples.
