David --- Many thanks for your prompt and thorough response --- and my sincere apologies for the comment about the PHREEQC database!!! I only meant that I couldn't find any information that directly addressed my problems with editing the database! Your advice is greatly appreciated. I would like to take this opportunity to let you know that I have been a PHREEQC user for about 3 weeks now, having switched from using MINTEQ... Although the learning curve for PHREEQC is somewhat daunting, I am very pleased with the code and am very glad that I decided to change. In all ways, a great improvement!! The FAQs (from the Web site) are also extremely helpful, and I refer to them frequently. I contacted Ken Stollenwerk because we are both working on arsenic, and he too has been really helpful. My sincere thanks to you both for your assistance. With gratitude, Carol Stein Gannett Fleming, Inc.
