Nitao, J J

The DEFUSE computer model is a convenient and simple tool for calculating the subsurface gaseous diffusion of volatile contaminants in the vadose zone for the purposes of guiding vadose zone characterization and data collection efforts and for determining the need for site remediation. The reader is referred to Nitao (1990) for further details on the conceptual model for contaminant transport in the vadose zone and an application of DEFUZE to a site at the Lawrence Livermore National Laboratory.
