Spring 2025 Virtual Retreat
“Geochemical Reaction Modeling”
April 7–10, 2025
Immerse yourself with like-minded colleagues from around the world to learn the ins and outs of Geochemical Reaction Modeling at our Spring 2025 Virtual Retreat. Taking part in this instructor-led, hands-on retreat, you will learn to use The Geochemist's Workbench® software to create quantitative models of multicomponent reaction processes in isothermal and polythermal geochemical systems.
The Retreat will convene over four consecutive half-days, April 7–10 from 8:00 to 11:30 CDT (13:00 to 16:30 UTC).
What you will learn. Following a fully hands-on format, you will learn all the ins and outs of the GWB reaction modeling toolset. Specific topics covered include:
- Aqueous speciation in natural waters
- Accounting for redox disequilibrium
- “Pitzer” activity models
- GSS, the Geochemist's Spreadsheet
- Reactions and reaction traces
- Surface complexation modeling
- The TEdit thermo dataset editor
- Chemical buffers in the natural environment
- Fluid mixing and scaling
- Geothermometry
- Waste injection wells
- The Phase2 phase diagram generator
- Modeling kinetic reactions
- Overview of reactive transport modeling
The topics will be illustrated through a series of case studies.
Prerequisites: There are no advance requirements for this course, but we suggest you acquaint yourself with basic techniques for configuring the GWB apps.

Thank you for the GWB workshop—it was perfect! The tasks made the learning process really easy.
– Yuchen Liu, University of Illinois
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!

Please expect an email containing a meeting ID and password in the days leading up to the event.
Before the retreat
As the retreat date approaches, please take note of the following:
- About a week ahead of the event, we will send you a free 30-day license to The Geochemist's Workbench® Professional, along with the retreat schedule and two pdf files.
- Please make sure GWB Professional is installed and activated on a computer running MS Windows before joining.
- The first pdf file holds the complete set of PowerPoint slides to be shown by the instructors, in chronologic order, for your reference during and after the event.
- We recommend you print and spiral bind the second pdf file, containing the workbook you will use to complete hands-on exercises.
- We think you will be happiest if you have two computer screens available. That way, you will be able to take part in the event on one screen, while you use the other to run the software.
