This paper presents the results of laboratory experiments that investigate the removal of volatile organic compounds from saturated soils through the use of air sparging. Three series of experiments were performed in a column test apparatus using two different soils to represent actual field conditions, namely, a fine gravel and a medium to fine Ottawa sand (both obtained from sources near Chic...

Innovative monitoring probes based on a diffusion cell concept (Barber and Briegel, 1987) have been developed to provide in situ, undisturbed and on-line measurements of parameters of interest under variably-saturated conditions during remediation and contaminant monitoring. Probes for oxygen and volatile organic compounds (VOCs) have been tested in three field trials of in situ remediation; tw...
