The nonaqueous-phase liquid (NAPL)–water interfacial area and the mass transfer rate across the NAPL and water interface are often key factors in in situ groundwater pollution treatment. ...
Active subsurface heating extended from approximately 5 feet below grade surface (ft bgs) to just below the bedrock surface, The goal of the ERH remediation was to removal NAPL and reduce the average soil concentratbn of TCE to 10 mg/kg. Post ERH soil sample analyses indicated a removal efficiency of 95.5%. Background The treatment region was ...
Treatment depths vary across the site from approximately 15 to 32 ft bgs based on the actual bedrock surface identified during wellfield installation. The remediation goal is to remove NAPL in overburden soils (from ground surface down to bedrock, with "NAPL removal" defined by meeting project-specific soil cleanup goals defined ...
In Situ Thermal Remediation with Gas Thermal Remediation (GTR©) is being used to remove NAPL contaminants from a former military base. The system is extracting 378 liters (100 gallons) of liquid waste every week. LNAPLs, such as fuel and oils, and DNAPLs, such as PCBs and chlorinated solvents, are being removed from the subsurface to make ...
In Situ Thermal Remediation with Gas Thermal Remediation (GTR©) is being used to remove NAPL contaminants from a former military base. The system is extracting nearly 1,000 liters of liquid waster every week. ...
Challenge: Nonaqueous-phase liquid (NAPL) was detected on a limited portion of the completed sand cap at the Pine Street Canal Superfund Site. ...
