PROPOSED SOIL REMEDIATION PROTOCOL <br /> As conventional excavation techniques will already have been <br /> employed to remove soils available for remediation in this <br /> manner, it is proposed that the remaining contaminated soil <br /> be bioremediated in-situ as an adjunct to the water treatment <br /> ' system described above. Here, a portion of the extracted water <br /> which has been remediated within the fluidized-bed bioreactor <br /> would be introduced in the area of residual soil contamination <br /> through infection wells and infiltration galleries . This water, <br /> by virtue of having been treated, would be rich in dissolved <br /> oxygen, nutrients, and populations of non-pathogenic, hydrocarbon <br />' utilizing bacteria capable of thoroughly degrading the <br /> petroleumhydrocarbons remaining within subsurface soils . The <br /> design of the in3ection/infiltration network will be finalized <br /> upon completion of the calculations necessary for construction <br />' of the water treatment system. An overview of the proposed <br /> soils treatment system concept appears as Figure ##A-2 . <br /> 1 <br /> IV. <br /> i <br />
