Dr. Parkhurst, It is very nice of you to have acknowledged my request to be on the mailing list. I hope that this is not an automatic answering system, and that you actually read the e-mail message. I got a Ph.D. from Montana State University in 1992 and Bill Inskeep was my advisor. Where can I find more reaction equilibrium constants for several more metals that are not in your PHREEQC database? I have found some constants but not complete, especially those reactions with chloride ions are hard to find. Your directions will be greatly appreciated. Thank you for your valuable time. I can not thank you enough for producing such a wonderful computer program. Best wishes, Sam Chen, Ph.D.
