PhD/Postdoc vacancy: Modelling of bioremediation processes and their electrical signature in the unsaturated zone
Institut des Sciences de la Terre d'Orléans Soils, sediments and groundwater are increasingly endangered by anthropogenic contamination, especially industrial pollutants from accidental spills, leaks or improper management.... Among persistent organic pollutants petroleum hydrocarbons (e.g., light NAPLs) are known to be toxic and carcinogenic for humans, and their contamination of soils and aquifers is of great environmental concern. Light-NAPLs have a tendency to stay at the top of the water table because they have a density lower than that of water and a low water solubility. They are highly volatile and very slow to degrade naturally because the residual phase is trapped in the smear zone between the vadose zone and the aquifer and they are not completely dissolved in the plume. In the context of the ecological transition, there is an urgent need to develop efficient and sustainable remediation techniques to clean up sites contaminated by LNAPLs. In situ bioremediation consists in changing environmental conditions (e.g., pH, temperature, water content, salinity, oxygen availability and nutrients) in order to stimulate growth of microorganisms degrading organic pollutants to less toxic compounds or removing them without adversely affecting the environment. Due to its cost-saving potential and the environmental benefit of in situ techniques compared to conventional ex situ techniques, the interest of commercial providers for enhanced bioremediation is steadily increasing. The position is located in Orléans, France at the Earth Sciences Institute of Orléans (ISTO). The PhD/Postdoc project is part of IMAGE, a project funded by the French National Agency for Research, that aims at deciphering the electric signature of processes associated with in-situ bioremediation. IMAGE is a consortium of academic and industrial partners including ISTO, BRGM (French Geological Survey), Sorbonne University, Geosciences Rennes, and IRIS Instrument.

PhD student – Particle transport by diffusiophoresis in porous media
Institut des Sciences de la Terre d'Orléans Many engineering applications foreseen the usage of small particles for groundwater remediation or for sealing damaged geological confinement barriers, however, delivering materia... ls to a contaminated or damaged region is challenging. The ERC project TRACE-it aims at controlling the flow of colloidal particles in subsurface geological environments using in situ solute concentration gradients. The phenomenon, known as diffusiophoresis, has a tremendous potential to move colloids to regions that are inaccessible by conventional transport. Diffusiophoretic transport in porous media, however, has received very little attention so far, especially in standard transport in porous media models where it remains unconsidered. The objective is to describe diffusiophoretic transport of colloids in porous media at the pore-scale, and to include diffusiophoresis in transport models at the macroscale. Given the state-of-the-art on diffusiophoretic transport, a description of this phenomenon in complex geometries is needed. Besides, in current diffusiophoresis models the distribution of chemical concentrations relies on oversimplified models, e.g. linear concentration profile in a straight channel. In this work, for the first time, we will couple solute distributions predicted for subsurface processes (task done in parallel of the PhD work) and diffusiophoretic transport, at the pore-scale and at the macroscale.
