Objectives
What trainees will gain
- Identify the types of contaminants and how they behave according to their properties.
- Understand the theoretical foundations of geochemistry and hydrodynamics needed to understand how contamination spreads.
- Run contaminant transport simulation models.
Content
What the programme covers
Hydrogeochemical processes
- Dilution, sorption, oxidation and reduction, natural and anthropogenic contamination, water–rock chemistry interactions, and contaminant transport mechanisms.
Contaminant migration processes
- Transport concepts in aquifers and soils: advection, dispersion and diffusion.
- Contaminant reactivity: reduction and oxidation, dissolution, ion exchange, sorption and complexation.
- Hydrodispersive and reactive modelling concepts: principles, required data, implementation and uncertainty, with a practical exercise building simple numerical models.
Case studies
- Site contamination by metals and metalloids, transport of hydrocarbons and chlorinated solvents, diffuse pollution by nitrates and plant protection products, and the dual approach to contaminant kinetics.
Who for
