Case study: Combined remedial approaches for CVOCs treatment in soil and groundwater: Excavation, MPE, and ISCR.
Case presented at Battelle´s Fifth International Symposium on Bioremediation and Sustainable Environmental Technologies in April 15-18, 2019, in Baltimore, Maryland.
Operations at a former diaper manufacturing plant located in São Paulo State (Brazil site), resulted in subsurface contamination by Chlorinated Volatile Organic Compounds (CVOCs), mainly Tetrachloroethylene (PCE), Trichloroethylene (TCE), cis 1,2-Dichloroethylene (1.2-DCE) and Vinyl Chloride (VC). PCE concentrations up to 54,000 ppb and a surface area of approximately 10,760 ft2 with vertical distribution extending to approximately 108 ft bgs. SGW employed a combination Soil Excavation, Multi-Phase Extraction (MPE), In Situ Chemical Reduction (ISCR) and additional Soil Vapor Extraction (SVE) to manage vapor intrusion and enable workspace utilization. From September of 2017 to June of 2018 the concentration of total CVOCs in groundwater was reduced from 31,200 to 500 ppb (>98%) without the accumulation of catabolites.
The quick and positive results of the remediation allowed the client to continue the project to implement the enterprise without loss in the original schedule, saving time and financial resources.
