Research Abstract
The objective of this study is to quantitatively evaluate the environmental risk and propose measures to reduce it, with the aim of preventing the landfill site that received disaster waste from becoming a negative legacy in the future. Of the 231 responses (valid response rate of 45%), 31 received disaster waste, and about 15% of them affected leachate treatment facilities. Increases in organic pollutants such as COD were confirmed at landfill sites with a relatively high landfill ratio. It was confirmed by the leaching test that the COD and sulfate ion concentration derived from the gypsum board and the COD and chloride ion concentration derived from the incineration residue were high. The cause of the increase in TN was unknown. No effect on generated gas and landfill temperature could be confirmed, suggesting the possibility that the effect on water quality deterioration will continue even after the completion of landfilling of disaster waste.
