Course number: NGEK12002U

Course content

The course attendants will:

  • Evaluate water-rock interactions controlling inorganic groundwater geochemistry and ultimately, drinking water quality.
  • Combine the use of classical methods and the 1D-reactive transport modeling (PHREEQC), to substantiate a qualitative and quantitative interpretation of water chemistry development along flow paths.
  • Trace water chemistry as it develops in the hydrological cycle: in rain water, through the aquifer and to its discharge, by using natural tracers.
  • Formulate problem-specific equations for geochemical processes encountered by moving groundwater, such as mineral dissolution and precipitation, ion exchange, diffusion and dispersion, surface adsorption and redox processes.
  • Use groundwater chemistry data to delineate hydrological processes such as flow paths and travel times, and vice versa.

Exercises and assignments comprise real datasets, presenting the students with major global groundwater quality issues of today.

Learning outcome

Knowledge:

Attendants will acquire knowledge on: Water quality and analysis accuracy; the relation between aqueous inorganic geochemistry, aquifer mineralogy and hydrogeology; controlling geochemical processes/water-rock interaction (mineral dissolution and precipitation, saturation state, ion exchange, surface complexation, redox reactions); diffusion and dispersion in relation to groundwater chemistry; stable isotope hydrology; chemical speciation, batch and 1D reactive transport modeling with PHREEQC (generic aqueous geochemistry code).

Skills:

Attendants will acquire skills to: Assess quality of water and water analyses; write and make use of reaction equations for various water-rock interactions, and equations for diffusion/dispersion and isotope fractionation; assess controlling geochemical processes based on water analyses, aquifer mineralogy and hydrogeology; conduct chemical speciation, batch and 1D reactive transport modeling with PHREEQC.

Competences:

Competences acquired: Break-down data sets of water analyses, aquifer mineralogy and hydrology to evaluate qualitatively and quantitatively the geochemical and hydrogeological processes controlling groundwater chemistry and drinking water quality. Combine and reformulate general chemical reaction equations for aqueous and solid-aqueous processes into problem-specific reaction equations which clearly express the nature of the problem. To formulate and test hypotheses, and make predictions, regarding groundwater geochemistry by conducting numerical speciation, batch and reactive transport modeling.
