Title

Site 8 SVE and Biovent System Installation and Work Plan, Beale Air Force Base, California

Description

Site 8 is the Former J-57 Jet Engine Test Cell. Site 8 includes two concrete pads connected by asphalt paving, a former aboveground storage tank, a former septic leachfield, and a surface water drainage ditch. The primary objective of the Soil Vapor Extraction (SVE) removal action is to remove Volatile Organic Compounds (VOCs) contaminants from the vadose zone to minimize or prevent migration of VOCs to underlying groundwater of the surrounding areas. SVE removes VOC contaminants by applying a vacuum to the vadose-zone soils through a series of vertical extraction wells. The extracted vapors will be treated aboveground using granular-activated carbon (GAC) before they are discharged to the atmosphere. The primary objective of the Biovent removal action is to biologically degrade petroleum hydrocarbon contaminants impacting the vadose zone beneath the former Aboveground Storage Tank and to minimize or prevent migration of Total Petroeum Hydrocarbons to underlying groundwater. In-situ Bioventing stimulates the natural biodegradation of petroleum hydrocarbons by supplying oxygen to the existing indigenous microbes. TPH contamination is completely is completely mineralized into harmless byproducts, such as carbon dioxide and water.
