Terra Vac In situ Vacuum Extraction System: Applications Analysis Report

摘要

The report analyzes the results from the SITE Program's 56-day demonstration at the Valley Manufactured Product Company's site in Groveland, Massachusetts. Conclusions were reached concerning the technology's suitability for use in remediations involving both similar and different materials at other sites. Operational data and sampling and analysis information were monitored carefully to establish a database against which vendor's claims for the technology could be evaluated. Additional data on the technology's performance at other sites is also discussed. The conclusions from the results of the Groveland demonstration test and from other available data are: the process can be used to remediate a site contaminated with VOCs; the process can remove VOCs from soils with permeabilities as low as 10 to the 8th power cm/s; the process operates well in all weather conditions; and the process implementation costs can be as low as $20/ton, depending on various site-specific conditions.
