Aiding of the GPR method by other measurement techniques for liquid contamination detection

In the paper the selected results of measurements carried out for detection of two types of liquid contamination are presented. The authors made detection of contamination, which very often leaks to the ground, i.e. the low-conductivity hydrocarbon contamination and the high-conductivity chemical solution. Depending of the site and the type of contamination different measurement techniques were used: the GPR, the atmogeochemical measurement, the laboratory analysis, the resistivity imaging survey and the conductometry. A brief discussion about possibilities of liquid contamination detection using electrical and electromagnetic techniques is presented in the paper.
