Introduction
Vapor intrusion into inhabited buildings has been the focus of several studies over the years. Most of the early studies centered on radon and methane intrusion while more recent studies have shifted to concerns over vapor-forming chemicals that include volatile organic compounds (such as trichloroethylene), semi-volatile organic compounds (such as naphthalene), mercury, polychlorinated biphenyls and pesticides. As with radon and methane, the intrusion of vapor-forming chemicals raises concerns of health risk from exposure. Simulation of the migration of vaporforming chemicals from subsurface sources into overlying buildings provides a better understanding of the process, facilitates remediation, and guides field investigations. The objective of this example is to simulate chemical volatilization of trichloroethylene from a shallow contaminated groundwater table into cracks in the basement of an overlying threedimensional building. Migration of the volatile organic compound is mostly driven by diffusion in the ground and by advection at the ground/building interface. The exercise lends credibility to the use of the software in multi-dimensional problems involving vapor transport and diffusion.
