i 01 March 2004 . AGE-NC Project No 99-0645 IPage 7 of 11 in concentrations of 0 040 mg/Kg and 0 030 rng/Kg, respectively Results from V W 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 I 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 V W 1 B results indicated TPH-g was detected In all the soil vapor ' samples at concentrations ranging from 11,000 micrograms per liter(p g/L) to 14,000µg/L,benzene, toluene, ethylbenzene and xylenes were detected lin every sample at concentrations as high as 54 tig/L benzene, 1,400 µg/L toluene, 160 µg/L ethylbenzene, 990 µg/L xylenes, and MTBE was ' detected in all the samples ranging from 730 pg/L to 860 µg/L ' Toluene was detected in one sample collected from VW 1 A on 06 October at a concentration of 0 39 gg/L 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 chain-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 cfin 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 cfm and 31 cfrn, 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 i extraction well (VW 1 A) was always greater than 100 inches of water ' Advanced GeoEnviranmental,Inc
