Soil gas surveying of chlorinated solvents in relation to groundwater pollution studies

Abstract: Soil gas surveying is a method gaining in popularity for groundwater chlorinated solvent pollution studies, particularly in the USA. Previously published methods have advocated on-site analysis; this study presents a simple method where samples are transported to a laboratory for analysis, hence minimizing the need for specialized field analytical equipment and trained field personnel. Tests show the method provides reliable results, comparable with those of established on-site analysis methods. The soil gas s… Show more

“…4(c)) being placed adjacent to major saturated sandstone units, and two gas samplers ( Fig. 4(d)) being placed adjacent to sandstone units in the vadose zone (see Bishop et al 1991). Bentonite layers (1 m thick) were emplaced in the annulus using a tremmie pipe to form the hydraulic seals between sampler ports ( Fig.…”

“…Les résultats montrent que ce transfert de masse peut être important et dépend des paramètres expérimentaux comme le gradient de concentrations dans la frange capillaire (BARBER et al, 1990), le degré d'hétérogénéité du milieu (BISHOP et al, 1990), la vitesse et la dispersivité verticale du milieu (McCARTHY et JOHNSON, 1993), les fluctuations du toit de la nappe (THOMSON et al, 1997). Sur le site réel de Borden (base militaire canadienne), plusieurs études ont été effectuées afin de déterminer les principaux processus intervenant dans le transport des vapeurs dans la zone non saturée (CONANT et al, 1996;HUGHES et al, 1992) et de localiser la source de pollution ainsi que le panache des traces dissoutes dans la nappe à partir des mesures de concentrations en polluants dans la zone non saturée (RIVETT, 1995).…”
