Geochemistry and Pollution of Aquifers
Séquencement
Learning objectives
The objective of this course is to give the student engineer a basis that will allow him to deal with the various problems of transfer of organic and inorganic pollutants from the soil to deep aquifers: adsorption-desorption phenomena, thermodynamic balances, biodegradation, redox processes, ...
Reminders on the sampling of surface water and deep aquifers will allow it to be rigorous and critical of a water analysis before starting to exploit these data using geochemical modelling.
Prerequisites
Thermodynamics and physico-chemical phenomena of phase and mass transfer interactions.
Program
Reminders of basic concepts of geochemical modelling, laws of mass action, aqueous speciation, mass balance, ion balance, generalization of the concept of alkalinity, etc.
Sampling of surface waters and deep aquifers, validity of chemical analyses, filtration, field measurements, transport, conservation and analysis.
Interphase exchange reactions: ion exchange, surface complexation, dissolution - mineral precipitation, biodegradation and electron transfer (redox phenomenes).
The personal work required of the students engineers is the simulation under PHREEQC of the various laws implemented with applications to problems of acid mining drainage, chewers and soil pollution, physical-chemical characterization of sea and river water.
