Dear Members,
 
I have recently downloaded the WATEQ4F software and I primarily intend to
calculate the Saturation Indices of some minerals, especially that of calcite
and fluorite.
 
I have the following doubts;
 
1) I dont have (not calculated) Eh values for my ground water samples. So, what
should be the input value in Eh column? Whether it should be 0 or 9?
 
2) I have not measured the density of my water samples? So, what value should I
input under the Density column?
 
3) What should be the input value for Ehopt 1 to Ehopt 9? I dont have these
values?
 
Kindly help.
 
Thanks and regards;
Tejaswi
