(470 Pages: Text + Illustrations)
As part of its Soil and Water Investigation conducted
pursuant to California Code of Regulations Section 2725(f), the Responsible
Party in a soil and groundwater contamination case at a former gasoline
service station site conducted a feasibility study to evaluate vacuum
extraction of contaminants from soil and groundwater as a remedy for actual
or potential adverse effects of an unauthorized release.
This report describes the results of a Soil Vapor
Extraction Feasibility Study which was conducted to determine whether soil
vapor extraction could accomplish removal of contaminant mass at sufficient
rates, such that if carried out over a longer time period the method would
have the potential to achieve significant remediation. Parameters necessary
for the installation of a permanent SVE system such as Radius of Influence
(ROI; maximum distance from test extraction well at which magnitude of the
measured vacuum is at least 1% of the vacuum applied at the test well), and
a determination of the total number of SVE wells required in the final
installation at the former gas station site, were estimated in this report
from the data presented. MTBE Hydrocarbon Removal Rate, Efficiency of
Contaminant Mass Recovery and Total Petroleum Hydrocarbon are also estimated from the data presented in this report.
