There is 3 of us newly working with your software on different databases and we can't figure this out!!!! I have been spending 3 days on this so please anwser my questions. I am familiar with other sofware such as PHREEQC, AQUACHEM. I am trying to use Geochemist's workbench. The error on the chemical balance is twice as big in your sofware and I can't figure out why. How does it calculate the major elements or does it calculate the charge balance anyway? I usually enter the bicarbonates as alkalinity for CaCO3 wish is measured in the field in mg/L. All of my units are in mg/L. My elements are analysed under the form total Fe, Ca, Na.... Even if I use the same database wateq4f, it is not giving me the same results and the error is large with geochemist workbench??? Does-it even take in consideration the pe I entered in the input.
So my questions are;
1) Can you look at my data table and let me know if there is something wrong with my input
2) I received the results of S2- for H2S- under the fiorm of S2- (mg/L so in GWB do I enter it under HS- or S)???
3) Is there units incompatibitlty, should I change all my units in mg/Kg
4) Is there another way to enter data or a better way in a better form.
My goal is to make species diagrams and pe-pH diagrams with your software so first of all my analytes need to balance. The redox couples Fe2+, Fe3+, S2-/SO4, NH4, NO3, NO2 and other redox couple are important in speciation calculations.
I incuded my GWB sheet can someone tell me what is wrong?
Please help me find a solution.
