Users and uses

How can you use The Geochemist's Workbench® in your work? Here are a few examples of how people around the world apply the software:


Geochemists create in minutes diagrams and models that previously might have been calculated laboriously by hand, or computed using less accessible software.

Environmental remediators

Environmental remediators design, test, and optimize environmental clean-up initiatives costing tens of millions of dollars—before deploying remedies in the field.

Environmental chemists

Environmental chemists develop quantitative understandings of the mobility and bioavailability of heavy metals in the biosphere, and the persistence of organic contaminants.

Petroleum engineers

Petroleum engineers model scaling in wellbores and reservoirs, reservoir floods, and formation damage; they test the compatibility of fluids before they mix in the formation or wellbore.


Hydrogeologists construct fate and transport models accounting for dual porosity media, bioattenuation, contamination sorption, precipitation, and co-precipitation.

Nuclear engineers

Nuclear engineers create sophisticated models of radionuclide transport to design geologic repositories and remediate legacy contamination.


Geomicrobiologists figure the energy in natural waters available to microbes, how fast bugs respire and ferment, and how they affect their chemical environments.

Mining geologists

Mining geologists and engineers design solution mines and heap leach operations; they model the attenuation of acid drainage accounting for mixing, neutralization, sorption, and degassing.

Surface chemists

Surface chemists develop equilibrium and kinetic sorption models; they apply them to refine industrial processes and to understand natural phenomena.

Carbon sequestration

Carbon sequestration specialists study how captured carbon dioxide might react with subsurface minerals and engineered materials.

Electrolyte chemists

Electrolyte chemists use the package's ion activity models, including the Pitzer equations, to calculate species distributions and evaluate complexation kinetics.

Geothermal energy

Geothermal energy developers model heat and mass transport; they figure scaling risk in reservoirs, wellbores, and pipes, and predict reactions accompanying fluid mixing.

Geochemical kineticists

Geochemical kineticists derive rate models from their experiments and on the computer trace the progress of multiple kinetic reactions, serially or in parallel.

Exploration geologists

Exploration geologists develop genetic models of ore deposition, and interpret patterns in water composition that may lead to undiscovered resources.

Microbial engineers

Microbial ecologists use the software to design experimental studies of microbial reaction and growth, derive kinetic rate laws, and solve them alone or in combination.

Experimental geochemists

Experimental geochemists use the package to design laboratory tests that may last months or longer, and to interpret the results of their experiments.

Field geochemists

Field geochemists enter analyses into GSS datasheets, then with a few clicks convert units, calculate new parameters, and create specialized plots and diagrams.

Evolutionary biologists

Evolutionary biologists have used the package to model the synthesis of organic molecules, to gain insight into the origin of life.

Surface water

Surface water chemists use the software to account for atmosphere-water exchange, sediment-water transfer, and the effects of biologically mediated reactions.

Medical researchers

Medical researchers have traced passage of heavy metals through the mammalian digestive track.


Professors design practical exercises and classroom demonstrations that give their students experience solving real-life problems.


University students accomplish sophisticated calculations without being mired in repetitive detail as they learn about open-system chemistry.
