Please join us in one of our favorite places in the world, The City of Big Shoulders, Chicago, for two days of hands-on training in applied geochemical reaction modeling. Then, enjoy a springtime respite to take in Second City's architecture, theater, art, shopping, dining, and of course its hallmark Midwestern warmth and hospitality.

What you will learn. Following a fully hands-on format, you will learn to construct, trace, and interpret models of reaction in multi-component geochemical systems. Specific topics covered include:

  • Fluid mixing
  • Multicomponent equilibrium
  • Buffering reactions
  • Reaction, mass transfer kinetics
  • Kd, Freundlich, Langmuir sorption
  • Surface complexation
  • Polythermal reaction and mixing
  • Electrochemistry
  • Microbial catalysis and growth
  • Case studies and examples
  • Stability and phase diagrams
  • Effective graphical presentation

I had the best time during the workshop! I am 100% convinced all my models will be done in GWB from now on!

– Thais Lamana, Golder Associates

As someone inexperienced in both transport and modeling, I found that the course content was made very easy and transparent.

– Eline Feenstra, University of Fribourg

I was very impressed with the GWB Fate and Transport course in Johannesburg. It was well presented and very informative. I would recommend the course to any of my peers. Thank you, Brian and Craig!

– Altus Huisamen, Geo Pollution Technologies, Pretoria


The workshop will be presented by Brian Farrell. Brian is Lead Geochemist at Aqueous Solutions LLC, maker of The Geochemist's Workbench®.
