Boston 2018

Goldschmidt 2018 Workshop
“Reactive Transport Modeling in Geochemical Systems”
Boston, Massachusetts USA • 11-12 August 2018

Please join us in the heart of Boston, one of North America's most historic and beautiful cities, for two days of hands-on training in reactive transport modeling using The Geochemist's Workbench®. Then stay on in the Cradle of Liberty for the Goldschmidt 2018 conference.

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

  • Introduction to geochemical modeling
  • Transport in flowing groundwater
  • Dual porosity models (stagnant zones)
  • Kd, Freundlich, and Langmuir sorption
  • Surface complexation
  • Colloid-facilitated transport
  • Reaction kinetics
  • Biodegradation
  • Dissolution and precipitation
  • Microbial catalysis and growth
  • Effective graphical presentation
  • Creating animation and video

The topics will be illustrated through a series of case studies.

I loved the workshop! It was just the right combination of instruction plus hands‑on.

– Karen Kinsella, GZA GeoEnvironmental

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

Prior to the course I found the program daunting, but now I feel comfortable using it and am very impressed with what I can do.

– Ashlee D., Penn State University


The workshop will be presented by Craig Bethke, Brian Farrell, Kate Maher, Jenny Druhan, and Melika Sharifi. 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.

She has many years of experience as an instructor at the undergraduate and graduate levels, and as an effective mentor in the laboratory to less experienced scientists.


The workshop will be held at Boston University, two quick transit stops from the Conference venue at Hynes Convention Center. As the date approaches, please watch this space for specific information about the building and room number.


Registration for this workshop opens on or about January 1, 2018. If for some reason you would like to register before that date, please contact workshop support.

Environment and safety

Upon registration, you will be asked to provide an emergency contact name and telephone number, in the unlikely event of illness or accident. You will also have the option of requesting vegetarian lunches. Please alert the organizers if you have special needs of which they should be aware.

Central Boston is a relatively safe area, but visitors everywhere should take precautions to protect themselves and their belongings, such as closely securing wallets and purses, being alert to their environment, and walking with a companion, especially at night.
