Comment: |
Modeling first applied to OLSR (saline ground water); parameters and surface species of best fit from OLSR were applied to ALLMR water (fresh ground water)
UO2<2+> cation exchange was not considered because the study was at the pH range 7 to 10 and its contribution is found to be negligent by Bradbury and Baeyens (2009) in their study |
