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 ...
Soil vapor extraction (SVE) involves the use of multiple air injection points and multiple soil vapor extraction points that can be installed in contaminated soils to extract vapor phase contaminants above the water table. Contamination must be at least 3 feet (0.91 m) deep beneath the ground surface in order for the system to be effective.
A second round of soil vapor extraction from the contaminated site occurred in 2017 after years of planning and setup. [3] A SVE system was used to extract toxic vapor from soil on the site in a $10 million dollar operation. [4] By 2018 all equipment had been removed by the EPA.
Remediation efforts include capping the waste area, installation of surface water controls, a soil vapor extraction and remediation facility, fencing, and long-term monitoring of the site. Contaminated soil and waste material from up to 25 meters depth was removed from one of the waste pits between 1982 and 1984.
Herc Rentals is an equipment rental company, owned by Herc Holdings. It was formerly a subsidiary of The Hertz Corporation before being spun-off as a separate company in 2016.

California will use the funding to plug and remediate 206 high-risk orphaned oil and gas wells and decommission 47 attendant production facilities with about 70,000 feet of associated pipelines.
Equipment rental was first developed in Anglo-Saxon countries. It emerged in the UK after the First World War and has now become a multi-billion euro business providing a wide range of construction and industrial equipment for customers globally.The American Rental Association was founded as early as 1955, [1] and the first waves of consolidation took place in the 1970s in North America ...
The distance between electrodes and their location is determined from the heat transfer mechanisms associated with vapor extraction, electrical heating, and fluid movement in the contaminated zone. To determine the ideal pattern of electrode and extraction wells, a multi-phase, multi-component, 3-D thermal model is used to simulate the process.
