Summary
Abstract: PHREEQC- A Computer Program for Speciation, Batch-Reaction, One-Dimensional
Transport, and Inverse Geochemical Calculations is written in the C programming
language that is designed to perform a wide variety of low-temperature aqueous
geochemical calculations. PHREEQC is based on an ion-association aqueous model
and has capabilities for (1) speciation and saturation-index calculations; (2)
