The investigation of sites polluted with NAPLs (non aqueous phase liquids) such as BTEX (benzene, toluene, ethyl benzene and xylene) and chlorinated aliphatic hydrocarbons (CAH) is a real challenge. It has been demonstrated that the use of so called “conventional” field measurement techniques (drilling, placement of observation wells, ex-situ analysis of soilgroundwater samples) does not guarantee that a NAPL pollution is correctly characterized. To achieve a better detection it is advised to use conventional techniques in combination with “alternative” field measurement techniques such as MIP (Membrane Interphase Probe, SPGS (screen-point groundwater sampler) or CSIA (component-specific isotope analysis). The usefulness of these methods on the field is demonstrated for a selected site.
