This study was conducted to analyze the properties of deposit soil dredged from a reservoir which was processed for efficient treatment and management. Before starting this study, the physicochemical properties and the heavy metal content of the deposit soil were investigated to collect the fundamental data. In a treatment experiment proposed to use the deposit soil, the deposit soli was separated according to the particle diameter and only the cohesive soil having a diameter of 106 μm or smaller was used for plastic working after mixing it with a cross-linking agent. The dissolution experiment performed with the plastic worked deposit soil showed that the dissolution concentration was decreased as the plastic working temperature was increased. The dissolution concentration was drastically decreased especially in the 500oC to 1000oC interval of the plastic working temperature. For the future practical use, red clay was mixed with ceramic and a dissolution experiment and an experiment to calculate the saturated permeation coefficient were performed with the mixture. For the experiments, a module was prepared with the red clay to ceramic ratios of C-1 (5.3 L: red clay +ceramic=10:1), C-2 (5.3 L: red clay), and C-3 (2.65 L: ceramic, 2.65 L: red clay). Artificial sewage was injected to the module in which red clay and ceramic were mixed. The result showed that the pollutant dissolution concentration was higher when the dissolution time was longer. The pollutant dissolution concentration was in the order of C-1 > C-3 > C-2 with the C-1 as the highest. The saturated permeation coefficient showed a similar tendency with that of the pollutant dissolution concentration. The result showed that the initial pollutant dissolution concentration was low in C-2 in which only pure soil was included. As time passed, the pollutant dissolution concentration of C-1 and C-3 was decreased.
