Abstract

The Fugacity framework addresses multiple-media and multiple contaminant aspects of environmental site assessment based on a conceptual site model and a Fugacity Level I mathematical model. In an effort to help people use the Fugacity framework, a \“Fugacity Calculator Tool” was developed and implemented to enable users to visualize the behavior of toxic chemicals at a contaminated site, the effect of site-specific characteristics on contaminant distribution, the behavior of daughter products of degradation, and the associated risks to humans and the environment. The framework has been used in U.S. EPA RCRA/CERCLA workshops for identifying alternatives and decisions, and the Calculator is freely available and can be downloaded from the internet at the following URL: http://www.engi
