Hi,
I am trying to run Spec8 on several water samples.
After running the program the electrical conductivity yielded is much lower than the input EC(experimentally determined)(approx. 30% lower). Can someone tell me why please? Or how the program calculates EC.
Also the saturation indices of gypsum are not what is expected. The samples are expected to be saturated or nearly saturated in terms of gypsum but the indices are giving values indicating sub-saturation. Does anyone know why this might be?
Also we are seeing a large component of the SO4- being allocated to the neutral CaSO4 species. This is unexpected and seems to be affecting the output EC given in Spec8. Could someone clarify the controls on this species within the program?
I have attached a copy of the data set. If anyone is able to help it would be greatly appreciated.
