Help



Hello,
My name is Samuel Mutiti with Miami University, Oxfrod Ohio. I am trying
to run a simple speciation program using the win version of phreeqc that I
downloaded from your website. The problem I am having is that I am not
sure of how to write the program. So far I have been using the webphreeq
at http://www.ndsu.nodak.edu/webphreeq/. The only problem with this
webphreeq is that we are not getting the sulphide phases precipitating
when we expect to see sulphides. The other problem is that its limited on
what you can enter e.g you cannot enter both sulphide and sulphate
concentrations at the same time. I don't trust the our pe values so I
would like to let the program compute them using the sulphide/sulphate
ratios. I am attaching one of the outputs from for lake Fryxcell (which
shows the inputs). I am very thankful for your time and help.

Best Regards
