Vivek Patil Posted January 31, 2014 Share Posted January 31, 2014 Hello Brian and others, We collected some water composition data of a CO2-saturated spring. I tried to calculate the speciation, mineral saturation and charge imbalance using SpecE8. However, the charge imbalance calculated by SpecE8 is 11.09% while my manual calculations tell me it is 3.55 %. I am not sure why this is happening and if I am going wrong somewhere. I am not allowed to attach excel sheets here but I am attaching the input file of SpecE8. I used GWB 9.0. Thanks in advance for any help. Best, Vivek CGwater.sp8 Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted January 31, 2014 Share Posted January 31, 2014 Hi Vivek, The Environmental Applications of Geochemical Modeling textbook (section 5.4.3) has a discussion on the difference between calculating charge imbalance before and after speciation. I would take a look at this and see if it explains your problem. You might also double-check that you're using elemental equivalents correctly.
