| 摘要 |
The invention relates to a method and device for detecting soil pollution or cleaning up polluted soil in situ, respectively, in which: polluted air is extracted via one or more air drainage lines, which are located in the soil above the groundwater level, and/or polluted liquid is extracted via one or more further liquid drainage lines, which are located in the soil below the groundwater level, from the polluted soil, and the air and/or liquid thus extracted is analyzed or decontaminated. The air drainage lines extend principally horizontally and preferably lie at least 1 metre above the groundwater level. The liquid drainage lines extend principally horizontally and lie preferably at least 1 metre under the groundwater level. A reduced pressure of preferably 3 to 6 kPa is applied to the air drainage lines. To further prevent environmental pollution, vapours and waste fluids which are released are also collected and supplied preferably to the same decontamination device.
