Abstract: Open dumping is the most common method of solid waste disposal in many developing countries including Sri Lankan urban areas. Appropriate landfill site selection is important to minimize negative impacts associated with open dump sites. Landfill siting is an extremely difficult task to accomplish due to strong public opposition and regulations. Developing countries do not have a systematic process for landfill site selection and hence unsuccessful landfill siting leading to environmental degradation is typically the result especially in the developing world. Data were collected from Kandy district, Sri Lanka. Both GIS analysis and semi quantitative risk assessment were used and eight map layers such as surface water bodies, distance from transportation routes and urban areas, land use/land cover, soil, rainfall, population density, elevation were utilized.
