V-D L4 <br /> IN ,CC� <br /> *7S' <br /> Ifeasible due to the depth of the impacted soils and the lack of space on-site for utilizing heavy <br /> equipment during excavation and stockpiling of soils <br /> On-Site Soil Aeration <br /> I On-site soil aeration would require excavation of impacted soils and placement of cells and <br /> equipment for soil aeration As discussed under the Excavation Option above, further excavation <br /> of the site is not feasible due to the depth of the impacted soils and the lack of space on-site for <br /> I utilizing heavy equipment during excavation In addition, there is a lack of space on-site for <br /> placement of the treatment cells and equipment required for soil aeration <br /> Off-Site Soil Treatment <br /> Off-site soil treatment would require excavation of impacted soils and ample space for transport <br /> trucks to maneuver around the facility As discussed under the Excavation Option above, further <br /> excavation of the site is not feasible due to the depth of the impacted soils and the lack of space <br /> on-site for utilizing heavy equipment during excavation and loading of transport trucks <br /> Landfilling <br /> • Landfilling would require excavation of impacted soils and ample space for transport trucks to <br /> maneuver around the facility As discussed under the Excavation Option above, further <br /> excavation of the site is not feasible due to the depth of the impacted soils and the lack of space <br /> for utilizing heavy equipment during excavation and loading of transport trucks <br /> ISoil Venting <br /> Soil venting is used to remediate unsaturated zone soil A vacuum is applied to the soil to induce <br /> the controlled flow of air and remove volatile compounds from the soil Treatment of the off-gas <br /> is usually required <br /> Soil vapor extraction would be a viable technology for treatment of vadose zone soils at the site <br /> However, use of this technology alone would not meet the requirements for this site which <br /> include soil and groundwater remediation <br />' Groundwater Extraction and Treatment <br />' Groundwater extraction and treatment is an established technology that is widely used for <br /> containment and remediation of impacted groundwater Groundwater is withdrawn from one or <br />' more locations using wells or trenches at rates that depress the water table forming a cone of <br /> 6 <br /> 1 <br /> 1 <br />
