the modeled and experimental Kd values are not exactly the same, the trends describing the sorption
strength of ions relative to each other are well demonstrated in these predicted Kd values and the observed
trends discussed with regard to the site measurements in sections 1 and 2 above are supported. An
example of the model output for several constituents of interest is shown below. The aqueous changes for
redox active species are shown with the Kd data as appropriate.
