Be-ginning in 2002, source removal occurred using soil excavation, as well as single and multi-phase extraction. Groundwater remediation began in 2004 using liquid oxidant injections and later achieved final closure levels using ozone gas injection. Previous Remediation Efforts Initially 822 tons of contaminated soil were removed by excavator ...
In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — sometimes referred to as multi or dual phase extraction (MPE or — has further complicated the design requirements for safely applying off-gas treatment equipment. ...
In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — sometimes referred to as multi or dual phase extraction (MPE or DPE) — has further complicated the design requirements for safely applying off-gas treatment equipment. ...
This remediation plan consisted of excavation, sulfate injection, multiphase extraction and contingency using chemical oxidation; followed by Monitored Natural Attenuation (MNA). ...
Solution: Site assessment activities included hollow-stem auger drilling, air-rotary drilling, down hole video logging, packer tests, and installation of multi-level sampling wells to provide vertical dissolved phase delineation. In addition, tracer studies and private well sampling assessments to asses the direction and extent of the dissolved ...
Abstract A floating hydrocarbon plume at a manufacturing facility in Georgia was remediated using electrical resistance heating (ERH) and multi-phase extraction. The hydrocarbon was a specialty fuel similar to kerosene or diesel fuel. ...
Celtic designed a sophisticated groundwater treatment system, integrating air sparging, multi-phase extraction and chemical oxidation to address groundwater impacted by chlorinated solvents, which ranks as one of the largest chemical oxidation projects in the UK. ...
Pilot Test Six thermal conduction heating wells and one multi-phase extraction well were used for the pilot test. Subsurface heating progressed for 20 days until thermocouple data confirmed an averagetemperature of 100°C. LNAPL extraction rates increased from 17 ft3/h at 18°C to 52 ft3/h at 50°C, as measured by ...
Abstract A PCE DNAPL source zone was treated using thermal conduction heating combined with multi-phase extraction. Thick peat layers, even when contaminated with PCE DNAPL, were remediated to average soil PCE concentrations of 0.17 mg/kg (99.6% reduction compared to starting levels). ...
This paper presents the implementation and results of ET-DSP, an in-situ electrical soil heating technology, in combination with high vacuum dual phase extraction, to achieve the removal of vapour pressure sensitive BTEX compounds from under an occupied residential apartment building. ...
Currently, no other technology can offer equal levels of chlorinated non-aqueous phase liquids (NAPLs) cleanup in the same time frame and for the same price as ERH. ...
Untitled Document EXECUTIVE SUMMARY This document provides state-of-the-practice information on off-gas treatment technologies for soil vapor extraction (SVE) systems currently being used to clean up hazardous waste sites. ...
