| Short description: |
Accurate geostatistical properties and reliable effective transport coefficients of fractured soils and rocks are determined at multiple scales ranging from single fractures to fracture networks, by combining properly data from field-work and photo-geological analysis with lab-scale experiments and computational methods. This information is integrated into an updated numerical

simulator of the organic pollutant transport in fractured media (SIMUSCOPP). The simulator is used as a tool for the cost-effective calculation of the spatial and temporal distribution of the saturation of the bulk non-aqueous phase liquid (NAPL) in the unsaturated / saturated zones, and concentration of NAPL compounds in groundwater. Long-term numerical predictions of the chemical status of groundwater under various scenarios of pollution, that simulate the site contamination history, are coupled with additional information (e.g. exposure pathways, potential receptors, toxicity of substances, etc) for the risk assessment of fractured sites contaminated by organic pollutants. Two very different highly heterogeneous fractured sites which have been contaminated by the waste oils of industrial facilities are investigated to assess the risks threatened for the human health and ecosystem: (i) one site overlying granite rock and situated in North Spain; (ii) one site overlying clay till sediment and situated in an urban area of Denmark. The results of the project are helpful in formulating protocols for the risk assessment of fractured contaminated sites, and setting the boundaries of the protection zones of aquifers underlying fractured areas.
