Regarding SIT dataset in GWB 12.0/14.0

[Polly Tsai]

Dear Jia Wang,

 

I would like to transfer the NEA_TDB formatted with Phreeqc, the other geochemical code to the format of GWB. However, SIT (Specific ion Interaction) theory is used to calculate activity coefficients in the NEA TDB; whereas, to the best of my knowledge,  the Debye-Hückel or Pitzer equations are employed in the GWB. Is it possible to find any SIT dataset in other module of GWB? If any, can you demonstrate a right input format for me? Please refer to the attached text file [NEA_TDB_phreeqc_Nov2018 (UOH5 remove)].

 

Thanks for your kind assistance in dealing with my question.

 

Best regards,

 

 

Polly Tsai

Hello Polly,

Thank you for your message. The GWB does not currently support the SIT activity model. It will be added in an upcoming release in the next 6-8 months. 

Best regards,
