' Time Oil 5 <br /> 14000 East Highway 88 Lockeford,California May 27,1998 <br /> • TPH-g concentrations of 23,600 ppmv and non detect, respectively The <br /> influent and effluent data corresponds to a mass removal rate of 175 <br /> lbs/day with a destruction efficiency of 100% (Attachment B) <br /> Summary and Conclusions <br /> Based on the data collected during this SVE test and previous investigations, and by <br /> reviewing the lithology of the site, SVE appears to be a viable remedial alternative at the site <br /> (Pedersen and Curtis, 1991, & Peargin and Mohr, 1995) Based upon the data reviewed, <br /> SECOR recommends that a thermal oxidizer capable of 100 inches of water column and flow <br /> rates up to 250 cfm be used in conjunction with the existing Wells W-1 through W-8 The <br /> recommended treatment equipment and the existing wells should be sufficient to remove <br /> hydrocarbons from soils beneath the site <br /> If you have any questions regarding this letter report, please call us at (916) 364-1880 <br /> Sincerely, O�Off' <br /> Fay <br /> SECOR International Incorporated, �O <br /> f�v.60B5 ¢ <br /> Rusty E Benkosky Bower, R G ' OF CA��F <br /> Project Engineer Principal Geologist <br /> Attachments Table 1 - Soil Vapor Extraction Feasibility Test Data- W-1 <br /> Table 2 - Soil Vapor Extraction Feasibility Test Data- W-2 <br /> Table 3 - Soil Vapor Extraction Feasibility Test Data- W-3 <br /> Table 4 - Soil Vapor Extraction Feasibility Test Data- W-4 <br /> Table 5 - Soil Vapor Extraction Feasibility Test Data- W-5 <br /> Table 6 - Soil Vapor Extraction Feasibility Test Data - W-6 <br /> Table 7 - Soil Vapor Extraction Feasibility Test Data - W-7 <br /> Table 8 - Soil Vapor Extraction Feasibility Test Data - W-8 <br /> Table 9 - Soil Vapor Extraction Analytical Data <br /> Figure 1 - Site Location Map <br /> Figure 2 - Site Map <br /> Attachment A - Certified Analytical Reports and Chain-of-Custody <br /> Documentation <br /> Attachment B - Mass Removal Calculations Documentation <br /> 7GO05-001-01/iNFLTEST <br />
