After a short introduction to the program PhreeqC and existing data bases simple thermodynamic equilibrium reactions between aqueous, gaseous, and solid phases will be the focus.

This will demonstrate how changes in environmental
conditions affect the composition of natural waters, the distribution of
redoxsensitive species and the saturation with regard to certain gas or
mineral phases by dissolution and/or precipitation. Drinking water
treatment using open and closed aeration, addition of limestone or
mixing of different types of waters will be modeled as well as processes
of groundwater rehabilitation, e.g. nitrate reduction by addition of
methanol, the determination of the half life of reactive iron barriers,
or carbonate buffering of acidic groundwaters. Finally, we will turn to
more complex examples, considering kinetic processes and reactive
transport, e.g. tritium degradation in the unsaturated zone, sorption in
a lysimeter, surface complexation of arsenic on iron hydroxides and
regeneration of a double porosity aquifer in a former uranium in-situ
leaching mine (with WPhast). All exercises will be introduced with some
theoretical background and hints for their realization in PhreeqC;
afterwards all participants can work on their own computer with fulltime
individual supervision.
