  rdf:value "La extracción de vapores del suelo es una tecnología remedial in situ que reduce las concentraciones de constituyentes volátiles en productos derivados del petróleo absorbidos por los suelos en zonas no saturadas (vadosas). Se aplica vacío a través de los pozos cercanos a la fuente de contaminación del suelo. Los constituyentes volátiles de la masa contaminante se \"evaporan\" y los vapores son atraídos hacia los pozos de extracción. El vapor extraído es tratado entonces (generalmente con adsorción de carbono) antes de liberarlo a la atmósfera."@es, "Soil vapor extraction is an in situ remedial technology that reduces concentrations of volatile constituents in petroleum products adsorbed to soils in the unsaturated (vadose) zone. A vacuum is applied through wells near the source of contamination in the soil. Volatile constituents of the contaminant mass \"evaporate\" and the vapors are drawn toward extraction wells. Extracted vapor is then treated (commonly with carbon adsorption) before being released to the atmosphere."@en ;
