Rapid urbanization and industrialization are the root causes for increase in solid waste generation in developing countries. The improper disposal of solid waste in landfills results in leachate leakage. This in turn gets infiltrated into groundwater and causes severe health issues. Chennai, the capital city of Tamil Nadu state is the fourth largest metropolitan city in India. Municipal solid waste generation in Chennai city is nearly 4,500 million tonnes per day. There are two major dumpsites in Chennai, the Kodungaiyur dumpsite in North (2,300 million tonnes/day) and the Perungudi dumpsite in South (2,000 million tonnes/day). Kodungaiyur is a residential area and it comes under the Perambur Taluk of Zone IV (Tondiarpet) of the Corporation of Chennai. The study results revealed that the dumpsite area has increased by 37% and there is decrease of 49% in vegetative area, over a period of ten years. The vegetative area got slowly converted into a wasteland due to increase in the area of dumpsite. TDS, Calcium, Nickel, Iron, Copper, Phenol, Manganese, Ammonium and Chloride exceeds the permissible limit of BIS and WHO standards, which signifies the contamination of groundwater due to leachate. Leachate Pollution Index of the dumpsite was found to be 18.15, which is higher than 7.37, which is the permissible limit of leachate disposal of inland water surface. The contamination of groundwater results in severe health issues especially during the rainy season. Skin infection, diarrhea and Malaria are the top diseases, which people face frequently. 16.6% of people were affected by skin infection and diarrhea, 12.1% of people were affected by Malaria. This can be reduced by managing the leachate generated within the open dumps and producing zero waste at household level.
