Hi Melika, Thank you for your response. It was very helpful! I was able to add Cd (through TEdit) on thermo.tdat dataset, and model on SpecE8. Kind regards, Uche

Hello, I am using the annual GWB student's licence on GWB essentials guide to model for the equilibrium distribution of aqueous species in water on SpecE8. However, I encountered problems adding some elements on the Basis. I discovered that some elements such as As and Cd were missing on the dataset. I equally checked the online tutorials on the GWB websites for ways to add elements to the thermo dataset, but discovered the function is missing on the GWB student version. Actually, I hope to predict some secondary minerals precipitating or possibly dissolution in abandoned historical mining regions. The idea is to do a final check on the minerals predicted on the GWB with what I have physically. I have used the ACT2 to create the Eh-pH diagrams and stability for Haematite and Galena. However, to conclude my studies I need to suggest controls for the minerals with the model. Many thanks Uche
