A former industrial building located in Berkeley, California was impacted with Chlorinated Volatile Organic Compounds (CVOCs), including trichloroethene (TCE) and cis-1,2-dichloroethylene (cis-1,2-DCE); total petroleum hydrocarbons as gasoline (TPH-g), Dense Non-Aqueous Phase Liquid, and (DNAPL) and Light Non-Aqueous Phase Liquid (NAPL). A dual phase extraction system was permitted for site remediation.
Air sparge is an in situ groundwater remediation technology were air is injected into the groundwater to increase dissolved oxygen. Air sparge is used to remediate impacted groundwater with volatile organic compounds (VOCs), most commonly gasoline range organics.
Soil Vapor Extraction (SVE) is an in situ remediation technology designed to remediate soils impacted with volatile organic compounds (VOCs) including gasoline, and chlorinated hydrocarbons. This technology works by extracting soil vapor at a high vacuum using subsurface wells, then treating the soil vapor prior to discharge.
Site Closure Plan and Closure Strategy and Regulatory Support, Former Aerospace Site, Southern California
A soil vapor extraction system located at former aerospace site in Southern California had operated for a number of years. The client requested a strategy to obtain regulatory site closure. In response, a site closure plan was prepared outlining … Continue reading
The development plan for a former media manufacturing site impacted with volatile organic compounds (VOCs) and 1,4-Dioxane in groundwater included the construction of a large development in Westlake Village California. A feasibility study concluded that a pump-and treat system consisting of an advanced oxidation process combined with liquid phase activated carbon (LPGAC) was required. The follow-up work included preparing a detailed design, preparing NPDES permits for storm water discharge, process flow diagrams, layout diagrams, and process and instrumentation diagrams.
