AS/SVE definition
Examples of AS/SVE in a sentence
This enhanced biodegradation would accelerate rernediation over natural attenuation and AS/SVE by themselves.
Theestimate for this alternative assumes a 5-year period of operation of the in-Situ Air Sparging/Soil Vapor Extraction (AS/SVE) system.
The remedial action objectives for the interim action will be achieved by • installing a soil cover over the source; • performing soil vapor extraction (SVE) in the vadose zone beneath the pit; and • performing air sparging (coupled with SVE) in the 25,000 ug/L contour of the groundwater plume Specifically, the preferred alternatives for the Pit area at the CBRP OU are: Alternative S-3: Native Soil Cover and Alternative GW-3: In-Situ Air Sparging with Soil Vapor Extraction (AS/SVE).
Also included is the cost for the operation and maintenance of the AS/SVE system for a 5-year operation and maintenance period.
Installation, operation, and maintenance of the AS/SVE system could be readily implemented within a short time period.
The CMI/RD/RDR/RAWP details the actions to be taken for implementing the soil cover and AS/SVE remedies including a summary description of the scope of work for the remedial action design, monitoring requirements, a detailed implementation/submittal schedule for subsequent post-IROD documents, and an anticipated field activities start date.
AS/SVE will address principal threat wastes (i.e., highly concentrated TCE in the aquifer sediments immediately adjacent to the pit in the upper zoneof the water table aquifer) and VOC vadose zone contamination.
Installation of the AS/SVE system is targeted to remove high concentrations of TCE in the upper water table that could be in a free phase.
In-situ AS!SVE has been commonly used at other hazardous and mixed waste sites.
The AS/SVE system will prevent rapid migration from the upper water table to the lower table and will be consistent with the IRAOs. The use of AS/SVE to volatilize and extract the VOCs; in the upper water table will not result in significant releases of tritium to the environment or radiological hazards to workers because the tritium activities are very low.
