Soil Vapor Extraction(SVE) has become the most widespread and effective choice for soils treatment when the geology is favorable and the contaminants are volatile. An ideal application is the removal of volatile organic compounds(VOCs) which include gasoline contaminants from permeable soils. Horizontal or vertical slotted pipes are placed in the soils and a vacuum is applied, thus volatilizing the contaminants. The volatile organics are either directly discharged to the atmosphere... or treated before discharged...  4, fiche 1, Anglais, - soil%20vapor%20extraction

Un [...] système de dépollution du sol largement utilisé est l'extraction des contaminants volatils du sol. Ce système est généralement préféré si les composés organiques concernés sont volatils, si le sous-sol est poreux, et s'il existe un risque d'inhalation des vapeurs.  2, fiche 1, Français, - extraction%20des%20contaminants%20volatils%20du%20sol

Air stripping is a technology in which volatile organic compounds(VOCs) are transferred from extracted water to air. Typically, air stripping takes place in a packed tower(known as an air stripper) or an aeration tank. The air stripper includes a spray nozzle at the top of the tower. It sprays groundwater that has been pumped to the surface over the packing in the column. As the water descends, air is forced up through the column, stripping off the volatile compounds.... Air strippers transfer contaminants from one medium to another. There is no destruction of the contaminant. Consequently, the risks of emitting pollutants into the air must be carefully evaluated. Often, the air stream(or off-gas) is treated before it is emitted to the atmosphere.  2, fiche 2, Anglais, - air%20stripping

Le strippage à l'air consiste à extraire l'eau souterraine et à l'écouler goutte à goutte dans un appareil qui volatilise les contaminants au moyen d'un jet d'air circulant à contresens de l'eau. Les méthodes d'aération possibles comprennent les tours à garnissage, l'aération par diffusion d'air, l'aération à plateaux et l'aération par pulvérisation.  2, fiche 2, Français, - stripage%20%C3%A0%20l%27air

Some herbicides and insecticides are prone to vapour drift and can seriously hurt animals and humans. Vapour drift can occur even when there is no particle(droplet) drift, and even dry spray deposits can send vapours into the atmosphere. Vapour drift increases with air temperature, therefore the application of volatile products should be avoided on, or just preceding, hot days.  3, fiche 4, Anglais, - vapour%20drift
