ABSTRACT
This chapter provides sufficient information on in situ soil vapor stripping to give managers and regulators a clear idea of the range of applicability of the technique. It purposes to describe the studies that must be done to determine if soil vapor stripping is suitable for any given site. Site investigations normally break down into the following steps: a site history review; the preliminary site screening; detailed characterization of the site; contaminant assessment; and pilot testing. The chapter concerns the development of a phased approach to evaluation and implementation of vacuum extraction on a site-specific basis, and the mathematical models for implementing an approach. W. L. Crow et al. described data from soil vacuum extraction experiments carried out at a petroleum fuels terminal at which a gasoline spill had taken place. They concluded that the technique removes hydrocarbon vapors from the vadose zone effectively and is also useful in augmenting conventional methods for recovering spilled hydrocarbons from shallow aquifers.
