| Popis: | International audience; Light non-aqueous phase liquids (LNAPLs) are one of the most common sources of soil pollution worldwide. The Intergovernmental Panel on Climate Change (IPCC) predicts a significant increase of groundwater level fluctuations' intensity by 2100 that may greatly favor the remobilization of these contaminants in the environement. Yet, the effect of groundwater tables fluctuations on the LNAPL mobilization is not fully understood. To this aim, a new original experimental system combining in situ physical-chemical, geochemical, and indirect geophysical measurements was developed at the GISFI station, Homécourt, France to assess the effect of the groundwater level variations dynamic, under current and climate change conditions, on the LNAPL remobilization. Attention will be paid, especially, to the evolution of the concentration and composition of the dissolved LNAPL phase over time. Measurement, and monitoring of the pure LNAPL phase thickness and chemical composition variation will be also monitored. Numerical simulations of the LNAPL transport through the contaminated soil will also be carried out. These experiments should provide a better understanding of the fate of these hydrocarbons at contaminated soils and thus, a better assessment of the environmental risks associated with these contaminated sites and their evolution in the climate change context. |
