PHREEQC alk & exchanger output



Hi David,

I recently completed the PHREEQC course with Geoff Thyne who recommended
to contact you with this question. 

During my PhD years I developed inverse models using PHREEQC incl.
uncertainty to assess salinization of an aquifer in the Murray-Darling
Basin. 

My current focus, working with Jim Hendry, is developing reactive
transport models with PHREEQC for centrifugation experiments on clay
till, evaluating exchange coefficients & carbonate equilibria etc.
PHREEQC is useful to scale these experiments of diffusive-advective
transport at accelerated gravity to match solute diffusion profiles at
field scale.  

A question which I can't find addressed in FAQ:

Is it possible to identify exchangers and alkalinity for SELECTED_OUTPUT
with USER_PUNCH ?  It would be helpful to include exchanger composition
and to perform unit conversions for alkalinity etc. 

regards,
wendy
