SVE applies to volatile and semi-volatile organic … Webadsorbed state to a vapor phase. When used in combination with soil vapor extraction (SVE), air bubbles carry vapor phase contaminants to a SVE system which removes them. … WebExtraction effectiveness depends mainly on soil permeability, contaminant volatility, and the depth of the contaminated zone. More permeable soil gives better results. With deeper wells the vacuum is often lower, making contaminated vapor more difficult to draw. More volatile constituents vaporize more easily, and so are more easily extracted. small dining kitchen table
