Soil vapor extraction (SVE) is a physical treatment process for in situ remediation of volatile contaminants in vadose zone (unsaturated) soils (EPA, 2012). SVE (also referred to as in situ soil venting or vacuum extraction) is based on mass transfer of contaminant from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gas phase, with subsequent collection of the gas phase contamination at extraction wells. Extracted contaminant mass in the gas phase (an… WebMar 20, 2024 · -- The two horizontal vapor extraction wells were 130 to 200 feet deep with a screened interval of 80 to 100 feet, and were 40 feet apart. The wells were installed parallel to each other in a line extending from the west to the east side of the dry cleaning facility. -- The radius of influence of each SVE extraction well was expected to be 24 feet. WebOnce the extraction wells pull the air and vapors out of the ground, special air pollution control equipment collects them. The equipment separates the harmful vapors from the clean air. Air sparging works very much like soil vapor extraction. However, the wells that pump air into the ground are drilled into water-soaked soil below the water table. plantajuinen
