Tony Appelo and I are the authors of PHREEQC. It has been a long process, but our intent has been to produce an easy to use model that can simulate the major reactions in rock-water interactions. Currently, PHREEQC is available as a batch program, an interactive program (PhreeqcI and Notepad++), a C++ class with C and Fortran wrappers (IPhreeqc), and a COM (computer object model) that allows PHREEQC to be run in programs such as Excel and Matlab. The work has evolved to include reactive transport through (largely Tony's) additions to TRANSPORT capabilities, and my efforts at coupling chemical reactions with 3D transport models (PHAST).

Over the years, I have tried to answer all questions that have been posed to me, and I will continue to do so. However, I appreciate the efforts of the creators of this forum to provide a place where questions and information about using PHREEQC can be exchanged more openly. 

Charlie:
David and Tony have both made a substantial contribution to science, and continue to be extremely generous with their time and expertise, which is greatly appreciated.  David, it is fantastic to have your involvement here, and we hope that this community will continue to grow, and learn more about the capabilities of PHREEQC and see how it can be successfully applied.  We will be developing more features here soon, which we hope will be of benefit to novices and experts alike.

Hello David

I have met Tony at his course in Amsterdam last year, and I hope I have the honor of meeting you one day. Thank you for joining the forum, I love PHREEQC and think it is amazing. I hope you will be able to answer some questions for me in the future.

Thanks Mr. David Parkhurst, I hope one day will have the opportunity to invite a cup of coffe (or a beer) jaja.
