(JP11239784-A)   NOVELTY - An apparatus for soil remediation to remedy a pollutant contaminated soil comprises: (a) excavating means; (b) agitating means; (c) feeding means; and (d) measuring means, to measure pollutant concentration in soil.    USE - The apparatus and the method is useful for purifying contaminated soil and remedying pollutant contaminated soil. Phenol contaminated soil (10 ppm) was subjected to remediation using the above method and apparatus. After remediation, the concentration of the phenol was 0.2 ppm at each point, which indicated that soil remediation was complete. Where the soil was not dug and agitated, the concentration of phenol was 9.7 ppm.    ADVANTAGE - Purification of the contaminated soil which can diminish the influence on the ecological system of the environment to be remedied as much as possible, carrying out in situ environmental remediation more effectively. By controlling and remedying treatment according to the sites and the pollutant concentration in the contaminated soil, it is possible to suppress the level of disturbance of the ecological system due to the introduced microorganism, nutrients and/or inducer. In addition, the method makes unnecessary to add the microorganism, nutrients or inducer superfluously to the soil, enabling more efficient remediation of the contaminated soil.
