Safe and reliable disposal of municipal solid wastes and residues is an important component of integrated waste management. Open dumps, commonly found in Asian countries, are land disposal sites at which solid wastes are disposed of in such a manner that does not protect the environment, susceptible to open burning, and exposed to disease vectors and scavengers. Leachate is a polluted liquid emanating from the base of the landfill, which contains innumerable organic and inorganic compounds generated due to which serious ground water contamination was observed in wells. Present paper is a case study of Uruli Devachi (Open dump site), near Pune (M.S.) where daily 1000–1200 tonnes of solid waste are disposed at Uruli-Devachi village, and the site was dealing with problems of frequent fires, smoke, flies, birds and bad odour. PMC was spraying the waste with water to prevent fires, resulting in even greater quantities of leachate generated due to which Serious ground water contamination was observed in wells
