Dear Dr.David Parkhurst: How are you. After finishing my study in Oslo, I moved to the States last month as a post-doctor currently at Lawrence Berkeley National Lab. When I use PHREEQC to solve some problems, I got some trouble in explaining the results, for example, activity higher molality for the same species. The reason for this is due to the limitation of PHREEQC in handling high ion-strength solution. Do we have some way to solve this problem? or if you have other programs which can be used to solve this problem. Please let me know. Thanks. Best Regards, Zuoping Zheng LBNL Tel: 510-486-6472
