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

Register now
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.

Goldschmidt workshop registrationSPECIAL OFFER: Sign up for the Goldschmidt workshop for only US$140 when you register for the Goldschmidt 2018 conference!

Online registration for the Goldschmidt Conference closes July 12, 2018, so don't delay!

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 [geochemical modeling] workshop! In the future I would really like to take the reactive transport course.

– Ryan Davis, Colorado State University

I thought the workshop was fantastic! The pacing and examples were very good and the course gave me a lot of ideas on how I can better use GWB.

– Morgan Warren, Golder Associates

I have been modeling with GWB for several years now but I always learn something new at the workshops.

– Johan Fourie, Geostratum Groundwater & Geochemistry Consulting


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.


Register Now

Space is limited, so sign up early. You may join the workshop when you register for Goldschmidt 2018, or you may sign up directly with the workshop organizers.

The workshop fee is only US$140 when you attend as part of the conference, which is the least expensive way to take part. To take advantage of the Conference's early registration discount, be sure to sign up by June 12. Please note the Goldschmidt Conference cuts off registration for all workshops on July 12.

Alternatively, you may register directly with the workshop organizers, without attending the meeting, at the undiscounted price. In this case, the workshop fee is US$599 until July 12, or $699 after that date. Full-time students currently enrolled in a university degree program can register at the reduced rate of US$499, or $599 after July 12. Please bring current student identification to the workshop.

We are pleased to welcome back participants from our previous workshops at a special discount. For fastest verification, please sign up with the email address you used registering for the earlier course.

In either case, the workshop fee includes all course materials, coffee breaks, and lunch each day. Each registered participant will receive a free 60-day license to The Geochemist's Workbench® 12 Professional version. We will ask you to bring to the course a laptop with the software installed and running.

Fees paid through the Goldschmidt are subject to Conference policies. A registration made with the workshop organizers may be transfered to another participant at no charge, and is fully refundable until 30 days before the workshop. In either case, liability in the event of workshop cancellation or other eventuality is limited to refund of the registration fee.


The Goldschmidt Conference has kindly arranged low-cost accommodations for workshop participants on Boston University's campus for only $85 per night.

A limited number private rooms with shared bathrooms and views of the Charles River and Downtown Boston are available. The rooms offer easy access to the workshop venue, as well as the main Conference afterward. Register at BU's event housing page.

The Goldschmidt has further arranged negotiated rates at hotels nearby. Please visit the Conference accommodation page for details. Again, a limited number of rooms are available.

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.
