[OLD] Multiple Species

Subject: Multiple Species

The water analyses from which I am trying to input the data include multiple species: for example, ammonium and nitrate plus sulfide and sulfate. I understand that one can be swapped in but does this not change the basis so that only one of the species is accepted in the modeling? Is there a technique to enter multiple species?

When you have analyses of an element in its different redox states, you use the "decouple" command to configure a model accounting for redox disequilibrium in the fluid. For discussion and examples of doing so, consult the green book and the GWB User's Guide.
