| Zusammenfassung |
| Groundwater as natural resources is one of the main sources of water for agricultural, industrial and domestic in developed or developing countries. However this resource, which was considered of good quality, is now threatened by various sources of contamination by human activities. This is the case of the District of Abidjan which has been the victim of toxic waste in 2006 and of an alpine valley in Western Switzerland.
Groundwater from these two sites is located in sandy and unconfined aquifers. In fact, the pollutant transport in porous media is influenced by a variety of physical, chemical or biological, complex and interdependent.
In Switzerland, where data are available, we simulated steady-state flow and tetrachloroethene transport with a good result showing the tetrachloroethene plume. While in Abidjan, where the data are insufficient, we developed in steady and transient states, flow and contaminants transport models in order to predict the likely evolution of the contaminants in the basement. Contaminants are composed of a very high contents of hydrogen sulfide, organochlorines, sulfur, mercaptan sulfur, and hydrocarbons such as olefins, Paraffins. We made two parametric and comparative studies. The probability of contamination of groundwater is observed over time, taking into account the input parameters of the model and some assumptions. |
