Hazardous Waste Identification Rule

Description:

MINTEQA2 is an equilibrium speciation model that can be used to calculate the equilibrium composition of dilute aqueous solutions in the laboratory or in natural aqueous systems. The model is useful for calculating the equilibrium mass distribution among dissolved species, absorbed species, and multiple solid phases under a variety of conditions including a gas phase with constant partial pressures. PRODEFA2, the Problem Definition Program for MINTEQA2, is an interactive program that assists the user in developing and building an input data file for the MINTEQA2 model.
