MINTEQA2 - geochemical equilibrium speciation model
MINTEQA2 Category: geochemical models
MINTEQA2 Overview
MINTEQA2 is a U.S. EPA geochemical equilibrium speciation model capable of computing equilibria among the dissolved, adsorbed, solid, and gas phases in an environmental setting. MINTEQA2 includes an extensive database of reliable thermodynamic data that is accessible to PRODEFA2, an interactive program designed to be executed prior to MINTEQA2 for the purpose of creating the required MINTEQA2 input file. MINTEQA2 generates reports at user-selected levels of detail. Reported parameters include the concentrations of all species in the system and saturation states of all solids. MINTEQA2 can be used to calculate Kd, the distribution coefficient between adsorbed and dissolved concentrations. This parameter is extremely useful in ground-water transport models.
