Goldschmidt 2021 Virtual Workshop
“An Introduction to the GWB Community Edition”
Presented ONLINE • 29 June–1 July 2021
Please join us from the comfort of your home or office for instructor-led, hands-on training on using the free
Community Edition of The Geochemist's Workbench®.
This powerful, immensely popular software package is available to geochemistry community worldwide at no cost.
The workshop will be presented as a fully interactive, instructor led online meeting for three consecutive half-days,
from 08:00 to 11:30 CDT (13:00 to 16:30 UTC) during the week leading up to the 2021 Goldschmidt Conference.
When we're done, hop on a plane, train, car, or handy scooter to Lyon, France,
where you can immerse yourself in the biggest geochemistry meeting of the year!
What you will learn. Following a fully hands-on format, you will learn all the ins and out of this advanced toolset. Specific topics covered include:
- Species distribution in solution
- Saturation and partial pressure
- Redox disequilibrium
- The geochemist's spreadsheet GSS
- Modeling inside GSS datasheets
- Brines and the “Pitzer equations”
- Automatic reaction balancing
- Equilibrium lines and equations
- Pourbaix, activity, solubility diagrams
- Surface complexation modeling
- Triple-layer and CD-MUSIC models
- The TEdit thermo data editor
Prerequisites: There are no advance requirements for this course beyond an interest in geochemistry and a willingness to learn.

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
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 best workshop I've ever participated in. The short theoretical introductions and illustrated exercises helped me learn the software in two days.

The workshop will be presented by Craig Bethke, Brian Farrell,
Jia Wang, Qusheng Jin,
and Matthew Kirk.
Prof. Bethke is the R.E. Grim Professor emeritus at the University of Illinois. He is the primary author of The Geochemist's Workbench® software package and author of the Geochemical and Biogeochemical Reaction Modeling text, published by Cambridge University Press.
Craig Bethke has been cited many times for excellence in teaching. He is a Fellow of the American Association for the Advancement of Science and recipient of a number of prizes in hydrogeology and geoscience, including the O.E. Meinzer Award and M.K. Hubbert Award.
Brian Farrell is the lead Geochemist at Aqueous Solutions LLC, makers of The Geochemist's Workbench®. Mr. Farrell is expert in aquifer microbiology, geochemical modeling, and reactive transport in geochemical systems. He has taught short courses in North and South America, Europe, Africa, Asia, and Australasia.
Jia Wang is an aqueous and isotope geochemist and a reactive transport modeler with special expertise
in weathering and the critical zone. She has many years of experience as an instructor at the undergraduate and graduate levels,
and as a noted mentor to less experienced students at the secondary through graduate levels.
Qusheng Jin is a professor of Earth Science at the University of Oregon.
Qusheng leverages his mechanistic understanding of biological processes to develop
new modeling theories and methods, and to apply them to natural and contaminated environments.
Cited for his University teaching accomplishments, Qusheng is an experienced workshop instructor.
Robert Sanford is an environmental microbiologist and microbial geochemist.
A Michigan State University Ph.D.,
he has extensive field, laboratory, and modeling experience across a spectrum of geochemical environments.
Rob is a noted educator and mentor at the University of Illinois, and uses the GWB extensively in his classroom.
Matthew Kirk is a professor in the Department of Geology at Kansas State University.
His research integrates concepts from geochemistry, microbiology, and hydrogeology to answer questions related
to water, energy, and the environment.
An experienced geochemical modeler, Matt has long structured his classroom teaching around the GWB.
Space is limited, so sign up early.
The workshop fee is US$260 until June 4, or $300 after that date.
A registration may be transfered to another participant at no charge, and is fully refundable until 30 days before the workshop. Liability in the event of workshop cancellation or other eventuality is limited to refund of the registration fee.
How to participate
Plan to enjoy this online workshop from the comfort of your own home or office!
We will use a secure video conferencing platform that allows participants to ask questions, share
their screens, and generally interact with the instructors and other participants.
Please plan to join the online meeting room from 13:00 to 16:30 UTC, or:
We will take periodic breaks between instructional units over the course of each meeting.
Please expect an email containing a meeting ID and password in the days leading up to the workshop.
Before the workshop
As the workshop date approaches, please take note of the following:
- Please make sure the free GWB Community Edition is installed and activated on a computer running Windows before joining the workshop.
- About a week ahead of the workshop, we will send you the workshop schedule along with two pdf files.
- The first pdf file holds the complete set of PowerPoint slides to be shown by workshop instructors,
in chronologic order, for your reference during and after the workshop.
- 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 workshop on one screen, while you
use the other to run the software.
