Dual Phase Extraction System, Permitting Design, and Construction | Berkeley CA
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.

Dual Phase Extraction (DPE) | Technology Description
Dual-Phase Extraction (DPE) is a remediation technology for soils and groundwater impacted with volatile organic compounds (VOCs). This technology works by extracting soil vapor and groundwater from the subsurface at a high vacuum, then treating the vapors and water prior to discharge.

Air Sparge | Technology Description
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 | Technology Description
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.

Lubricant Oil Spill Response, South Gate, California
An emergency cleanup response was executed after 7,000 gallons of lubricant oil were released. The release occurred as a result of railroad tank car colliding with a road tanker. The release affected soils in the vicinity of the incident, and impacted a nearby storm drain.

Feasibility Study for Management of Waste Activated Sludge, Manitoba, Canada
A food processor was experiencing low hydraulic residence times at one of their anaerobic digesters during the discharge of waste activated sludge. a feasibility study identified that the most cost-effective option was to thicken and anaerobically treat thickened waste activated sludge (TWAS) in a new digester designed specifically for that purpose.

Remediation of a Former Marine Terminal, Southern California
After a marine terminal was demolished, several site assessments revealed that soil and groundwater at the site were impacted with petroleum hydrocarbons and lead. An interim remedial action plan (IRAP), a Remedial Action Plan (RAP), and a Sampling and Analysis Plan (SAP) were prepared and implemented to protect harbor water, and remediate the site.
