Dear Mr. Parkhurst, Dear Mr. Appelo, I'm a Ph.D. student of Munich University / Germany and the focus of my thesis comprises thermodynamic modelling of seapage waters released by steel slags. Thereby I use the Program PhreeqC. Since the databases e.g. Wateq4f.dat of this program are rather limited concering the heavy metals chromium, molybdean and vanadium I am searching for better databases. Thereby my question concerns if you have information on the availability of better database which can be used in PhreeqC. Yet, I found the homepage of Chess, however the download of a PhreeqCdatabase is still named as under construction. I would be very pleased if you can give me a short information about the availability of databases or thermodynamical data for a self-made extension. Yours sincerely, Bernd Kottke
