The new introduced method for the soil contamination survey is based on the analysis of the soil gas or vapour. This newly developed method offers fast andreliable location of contaminant sourees and trajectories of the contaminant spread. Gas from the pore space in soil and rock formations is commonly known as soil vapour. The composition of this phase, in particular the présence and concentration of organic compounds, reveals vital information about pollution of the subsurface environment. Organic compounds constitute a group of contaminants which impact severely on groundwater resources. The presence and distribution of such pollutants can be detected by a new established technique known as a Soil Vapour Analysis ("SVA") or Soil Vapour Survey ("SVS").
