Iv <br /> L. - 05 May 2004 <br /> k...e AGE-NC Proj ect No. 01-0886 <br /> Page 5 of 6 <br /> BTEX constituents were only detected in soil samples collected from B-1 and. B-2. The highest <br /> Lim concentrations were detected in sample 132-30 at concentrations of 0.02 mg/kg(benzene),22 mg/kg <br /> (toluene), 29 mg/kg (ethylbenzene) and 170 mg/kg(total xylenes). <br /> MTBE was detected by EPA 802Prin one soil sample collected from soil boring B1-15 at a <br /> concentration of 0.08 mg/kg, however, these concentrations were not confirmed by EPA 8260 <br /> analysis of the same sample. 1,2-DCA and EDB were not detected above laboratory reporting limits <br /> Iv in the 10 soil samples analyzed by EPA 8260.Fuel oxygenating additives DIPE,ETBE,TAME and <br /> TBA were not detected above laboratory reporting limits in the same 10 soil samples analyzed by <br /> EPA 8260. Analytical results of soil samples are summarized in Table 1. The laboratory report <br /> +r (CTEL Laboratory Project Number CT214-0305028) and chain-of-custody form are included in <br /> Appendix B. <br /> 4.3. ANALYTICAL RESULTS OF GRAB GROUND WATER SAMPLES <br /> `r TPH-g was detected in grab groundwater samples 131-1120,B2-1-120 and B3-H2O at concentrations <br /> of 180 µg/l, 130 µg11 and 150 gg/l,respectively. TPH-d was not detected in any of the ground water <br /> samples analyzed. <br /> BTEX compounds were detected in each of the ground water samples; the highest concentrations <br /> re detected in sample B1-H2O at concentrations 5.6gg/1 (toluene), 3.0 µg/1 (ethylbenzene) and <br /> 1 .5 gg/l (total xylenes). Benzene was not detected in ground water samples. <br /> 6. y MTBE was detected in ground water samples B 1-H2O,B2-H2O and 133-1-120 at concentrations of <br /> 68 µg/1, 41 gg/l and 53 µg/1, respectively. <br /> LM 1,2-DCA was detected in ground water samples B1-H2O, 132-1-120 and B3-H20 at concentrations <br /> of 170 µg/1, 99 gg/l and 130 pg/l, respectively. <br /> LN Oxygenated fuel additives EDB,DIPE,ETBE,TAME and TBA were not detected above laboratory <br /> reporting limits in the three ground water samples. The analytical results of ground water samples <br /> are summarized in Table 2. The laboratory report (CTEL Laboratory Project Number CT214- <br /> �' 0305003) and chain-of-custody form are included in Appendix B. <br /> V <br /> 1.. t <br /> LW Advanced GeoEnvironmental,tne. <br /> LM <br />
