Dear Dr.Parkhurst, I am a graduate student in China University of Mining and Technology(Beijing) Now I am planing to carry out an investigation on acid mine drainage from a coal mine, and I find that PHREEQCI is usful to calculate the aqueous speciation and saturation index with respect to species of Fe. But I wondered that if the phreeqc database include schwertmannite ,if not,what kind data should I add to it? Thank you very much for you consideration! What you have done is good job!

Yours sincerely,
CONG
