r • 01 March 2004 AGE-NC Project No 99-0645 Page 7 of 11 In concentrations of 0 040 mg/Kg and 0 030 mg/Kg, respectively Results from VW 1 A showed TPH-g and TAME at 40 feet at concentrations of 4 6 mg/Kg and 0 01 Omg/Kg,respectively MTBE was detected from 40 to 60 feet,ranging from 0 030 mg/Kg to 4 2 mg/Kg Soil from VW3 had MTBE at 30 and 40 feet with concentrations of 0 020 mg/Kg and 0 060 mg/Kg, respectively No other target analytes were detected in the samples analyzed Analytical results of the soil samples are summarized in Table 2 The laboratory report(CTEL Lab Project No CT214-0309068),quality assurance and quality control (QA/QC) and chain-of-custody are included in Appendix E 33 ANALYTICAL RESULTS OF SVE SOIL VAPOR SAMPLES Analytical results of soil vapor samples were generally highest in the second sample collected on 18 • September Extraction well VW1B results indicated TPH-g was detected in all the soil vapor samples at concentrations ranging from11,000 micrograms per liter(gg/L) to 14,000 gg/L,benzene, toluene, ethylbenzene and xylenes were detected in every sample at concentrations as high as 54 gg/L benzene, 1,400 gg/L toluene, 160 gg/L ethylbenzene, 990 gg/L xylenes, and MTBE was detected in all the samples ranging from 730 gg/L to 860 gg/L Toluene and total xylene were detected in one sample collected from VW1A on 06 October at a concentration of 0 39 gg/L and 0 29gg/L, respectively No other analytes were detected at or above laboratory reporting limits in the soil vapor samples Analytical results of the vapor samples are included in Table 3 The laboratory report (MAI Lab Project No 0309365 and 0310096), QA/QC and cham-of-custody are included in Appendix F 34 SVE PILOT TEST RESULTS On 18 September and 06 October 2003,the SVE unit was operated at approximately 2,00 RPMs for the eight hour tests The shallow test results indicated the flow rate was initially measured at 42 cfm(standard cubic feet per minute) and the maximum observed was 75 cfm OV readings ranged from 923 ppm to 1,100 ppm Induced vacuum measured at the extraction well VW 1B ranged from 20 to 32 inches of water On 06 October 2003, the lower screened vapor extraction test indicted that the flow rate was measured between 25 cfin and 31 cfin, a much lower flow was observed OV readings ranged from 1 2 ppm to 2 5 ppm, which was consist across the pilot test Induced vacuum measured at the Advanced GeoEnvironmental,Inc
