【 摘 要 】

The passive soil vapor extraction (PSVE) system at the MetLab of the Savannah River Site has been operating since May 1998. The results to date on the treatability study indicate the technology is performing well. Well concentrations are decreasing and contour maps of the vadose zone soil gas plume show a decrease in the extent of the plume. In the 2 years of operation approximately 270 pounds of chlorinated organic contaminants have been removed by natural barometric pumping of wells fitted with BaroBall valves (low pressure check valves). The PSVE system is performing well in a cost-effective manner. It is recommended that this system be allowed to continue operating to complete the remediation and to continue monitoring activities to verify and monitor the anticipated contaminant removal rates. The treatability study should be considered successfully completed and the remediation should be considered in full operation.
