Development of an enhanced in-situ remediation technology using pneumatic fracturing and forced suction, and extraction of oil contaminated soil

Overview - Development of an underground treatment technology for contaminated soil with low water permeability coefficient
- Improvement of air and water permeability by injecting pressurized air using an injection well, at the same time, forcefully suck out air while extracting, so as to allow for seamless pneumatic fracturing
- Increase in efficiency of remediation and treatment of contaminated soil by systematizing physical, chemical and biological treatment methods so that they can be used together
