Abstract
A mathematical model for simulating the operation of soil vapor stripping wells for the removal of volatile contaminants is extended to examine the possible benefits of using passive vent wells to increase clean-up rates. Contrary to expectation, these do not generally seem to improve soil vapor stripping performance. The model is also used to examine recontamination of a vapor stripped vadose zone by vaporization and diffusion of underlying nonaqueous phase liquid and to investigate the possibility of removal of underlying light nonaqueous phase liquid pools by vapor stripping from the vadose zone.This publication has 3 references indexed in Scilit:
