General Description of the Research Project

Develop site-specific pollution control and remediation techniques for waste disposal sites utilizing locally-available materials
Unregulated waste dumping is a crucial contributor to social and environmental problems in developing countries. The project aims are 1) to carry out monitoring of soil and groundwater pollution, and perform environmental risk assessment at waste dumping sites and surrounding areas, 2) to develop sitespecific pollution control and remediation techniques for waste dumping sites utilizing locally available geo-/bio-materials, and to evaluate the developed techniques through a field scale study, and 3) to propose a guide for sustainable planning, management, and pollution control of waste landfills that is specifically linked and applicable to the waste management system in Sri Lanka.

Development of sustainable techniques to prevent contamination, with verification based on field scale study experiments
Solid waste management at local municipalities and soil and groundwater monitoring at selected disposal sites are being investigated. Utilizing locally-available materials, low-cost and site-specific pollution control and remediation techniques for waste dumping sites are developed. Field scale study experiments including these techniques will also be carried out. Integrating the results from these studies, applicable guide for planning, management, and pollution control of waste landfills will be formulated jointly with Sri Lankan ministries.
