“Reactive Transport Modeling in Geochemical Systems”
Paris, France • 12-13 August 2017

Please join us in the famed Latin Quarter of Paris, the world's most visited – and certainly most cherished – city, for two days of hands-on training in reactive transport modeling using The Geochemist's Workbench®. Then stay on in the City of Lights for the Goldschmidt 2017 conference.

While in Paris, stroll the historic neighborhoods, marvel at the architecture and monuments, visit exquisite museums, shop till you drop, come alive in the vibrant nightlife, and of course savor the food and drink of the world's capital of gastronomy.

Goldschmidt workshop registrationSPECIAL OFFER: Sign up for the Goldschmidt workshop for approximately €150 (final price TBD) when you register for the Goldschmidt 2017 conference!

Workshop registration through the Goldschmidt Conference opens February, 2017.

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

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

– Valeria B., Ben-Gurion University of the Negev

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, and Jenny Druhan. 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.

Register Now

Space is limited, so sign up early. You may join the workshop when you register for Goldschmidt 2017, or you may sign up directly with the workshop organizers.

The workshop fee is approximately €150 (final price TBD) when you attend as part of the conference, which is the least expensive way to take part. Workshop registration through the Goldschmidt opens February, 2017.

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 13, 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 13. 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® 11 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.


Paris is served by high speed rail lines terminating at stations within the city, as well as Charles de Gaulle (also known as Roissy) and Orly airports.

Paris is famous for its mass transport system. Arriving at a train station, you can transfer to the Metro and RER subways to conveniently reach a stop near your destination. From either airport, you may take the RER train into Paris; from Charles de Gaulle, RoissyBus is a roadway alternative. By train, reaching central Paris from the airport takes about 35 minutes, and the bus, about an hour.


A great many hotels and apartments are available to book in the vicinity of the workshop venue. In addition, the Jussieu Métro Station is conveniently accessible from a large area of Paris.

The Goldschmidt 2017 organisers maintain a page of suggested lodging near the Conference venue. Please note the workshop venue is about 30 minutes by Métro from Le Palais des Congrès, site of the Goldschmidt Conference.

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, as well as list any special dietary requirements or medical needs.

Paris is a relatively safe city, but no stranger to petty theft and property crime. Visitors everywhere should take precautions to protect themselves and their belongings, such as closely securing wallets and purses, being alert to pickpocket cons, and walking with a companion.
