To provide a method for measuring a VOC concentration in the ground on the ground, using a mixing treatment device, prior to purification, and a method for purifying soil and ground water which uses the measuring method.
In this method for measuring the VOC concentration in the ground, using the mixing processing equipment, the mixing treatment device for agitation-mixing a purification agent (material) into the soil is drilled into the soil, before purifying the original position for the soil and the ground water contaminated with a VOC, a microwave is emitted, at a prescribed depth, toward the soil from a VOC recovery device provided in the mixing treatment equipment; and a gas of the VOC vaporized from the soil on an irradiated face is taken into the VOC recovery device for measuring the concentration of the gas. In this original position purification method for the soil and the ground water, this original position measuring method is carried out for the soil and the ground water contaminated with the VOC, and the purification agent (material) is delivered thereafter, from the mixing treatment equipment to be agitation-mixed, based on measurement therein.
