POSTER PRESENTATION

Pilot test of combined techniques to optimize the remedial approach of a LNAPL contaminated site in Brazil

This complex steel plant in Brazil, located on a shale rock alteration soil/aquifer, has several areas impacted by petroleum hydrocarbons such as BTEX and PAHs. Initially, it was performed a Smart Characterization® approach to build a mass-flux based conceptual model and map the NAPL presence areas. A Pilot test of Dual Phase Extraction (DPE) were conducted with treated and oxygenated groundwater recirculation to accelerate the soil flushing optimizing the mass removal rates and biodegradation. After 5 days of test, combined air sparging was used, aiming to increase the rates of mass removal in the residual/adsorved mass. The results demonstrated good applicability for the combined techniques, 2 kg of contaminant mass was removed, 43% of the total mass removed during the combined DPE and AS techniques.
