The interface is easy to use, and I really like the graphics.
− Joe O, Penn State University
I love the GWB and wouldn't consider using another modeling program.
– Jonathan B., University of Alberta
Reactive Transport Modeling
I like the scalability of the software, from running basic mixing calculations to reactive transport models.
− Elisabeth E., Thermochem, Inc.
Thank you very much for the workshop. It was intense but very, very useful and clear.
− Samantha Y., Stanford University
