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. 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.

We are pleased to announce the release of a user-friendly version of MINTEQA2 designed for Windows 95/98/2000/XP systems. MINTEQA2 for Windows can do all of the calculations that the official U.S.EPA DOS version can do and it uses the same thermodynamic database. It provides an intuitive graphical user interface using the familiar Windows conventions. MINTEQA2 for Windows computes the equilibrium composition of a multi-component aqueous system including the mass of each component in solution, sorbed, or precipitated.
