Create reactive-transport simulations and perform different aqueous geochemical calculations like speciation and saturation-index or reaction-path and advective-transport calculations. Work with various aqueous models, including two ion-association aqueous models, a Pitzer specific-ion-interaction aqueous model, and the Specific Ion Interaction Theory aqueous model.

From the developer:
PHREEQC is a computer program written in the C++ and C programming languages that is designed to perform a wide variety of aqueous geochemical calculations. PHREEQC implements several types of aqueous models: two ion-association aqueous models (the Lawrence Livermore National Laboratory model and WATEQ4F), a Pitzer specific-ion-interaction aqueous model, and the SIT (Specific ion Interaction Theory) aqueous model.
