Freyer Ciencias de la Tierra NAPL radon soil gas remediation detection method The dependence of the soil gas radon concentration on ground contamination by non-aqueous phase-liquids (NAPLs) wasstudied. Subsurface NAPL contamination is known as one of the major problems concerning the clean-up of polluted industrialsites. One reason is the mostly limited number of soil sampling locations, which makes adequate tracing of the extent of contaminationdifficult. With the aim to enable a more detailed assessment of NAPL plumes a new indirect method for NAPL detectionhas been developed. The method uses the good solubility of radon in NAPLs which enables the NAPLs to partly accumulate theradon available in the soil pores. Radon enrichment in the NAPL causes a local decrease of the soil gas radon concentration in thevicinity of the NAPL contamination. Thus radon minima can be used to localize NAPL plumes indirectly. The results of thepresent investigation suggest that the radon concentration in soil gas may be used as a complementary tool for the detection of subsurfaceNAPL contamination together with conventional investigation methods. 2002 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56841412 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.41 |
