WebWater table dynamics, dissolved oxygen (DO) content, electrical resistivity (ER) in monitoring wells and air pressure in the vadose zone are monitored in air sparging (AS) accompanied by soil vapor extraction (SVE) at a hydrocarbon-contaminated groundwater site in Oman, where a diesel spillover affected a heterogeneous unconfined aquifer.
WebMulti-phase extraction (MPE) involves removing contaminated soil vapors, free product and groundwater with one (1) remediation system and from common extraction wells under high vacuum conditions. MPE increases the vapor extraction zone of influence by lowering the water table and therefore increasing the air-phase permeabilities in the vadose ...
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.
WebSoil vapor extraction (SVE) is a commonly used technology for VOCs in soils that EPA has selected as a “presumptive remedy” (see bibliography at the end of this paper). SVE is an in situ treatment technology that uses vacuum blowers and extraction wells to strip volatile compounds from unsaturated soil. dwight bond mesa azWebSoil Vapor Extraction (SVE) Applicability as a method of vapor intrusion (VI) mitigation.
