| Rn emanometry has been validated as screening technique of sites affected by non-aqueous phase liquids (NAPLs) where the subsurface structure does not present significant spatial variations. When there are fractures or changes in soil permeability, background emanation varies spatially, making it difficult to discriminate whether the decrease in the signal is due to the presence of NAPL. This paper presents the results of two methodological applications that manage this problem. First, data variography analysis is used to identify subpopulations. The delimitation of signal decrease is performed by comparison with local background values associated with different soil structures. In the second approach, emanometry determinations are coupled with electrical tomography profiles combined with induced polarization measurements, allowing to support the estimation of NAPL distribution. | |
