Thanks for the letting me know your plans. PhreeqcI is public domain and may be distributed in any way that you want, though we appreciate the acknowledgements. Scott Charlton has developed the InstallShield installation for PhreeqcI and he has been careful to ensure that it runs on all versions of Windows from 95 on. He tried to avoid requiring administrator privileges, but that was not possible for a couple of the systems. It installs various dlls, so I suppose there is a potential for conflict with AquaChem if they use different versions of the same dll. We have had only two or three complaints about installation problems and as far as we could tell, the problems were caused by serious flaws in the configuration of the user's machines.

We are just now finalizing the next release of AquaChem v.4.0. This version will include a simplified interface to PHREEQC for calculating saturation indices of water samples from the AquaChem database. However, I would also like to include the installation for PHREEQC-I together with the AquaChem installation so our users will have access to a better interface to the rest of the PHREEQC functionality. The PHREEQC-I installation will be provided as an additional service to the user so they do not have to download the files from the USGS web site, but we will not be charging them for this service. Of course, we will acknowledge yourself and the USGS in the documentation, and the PHREEQC-I installation will not be altered in any way. I am writing to you to see if you forsee any problem with doing this. I appreciate your assistance in this matter and I look forward to your response. Best regards, Patrick Delaney Vice President, Software Development Waterloo Hydrogeologic, Inc.
