  • Process for remediating soil
    Patent number: 5803664
    Abstract: A process for remedying polluted soil which comprises the steps of injecting a liquid agent containing a microorganism into the polluted soil, and injecting a gas into a region wherein the water content of the soil became 0.6 or more times its saturation water content after the injection of the liquid agent. Using this method bioremediation of contaminated soil can be economically and efficiently carried out.
