BTEX compounds were <br /> reported detected in soil samples B 1-50 and B 1-60 at maximum concentrations of 0.026 milligrams <br /> per kilogram (mg/kg) benzene (B 1-60), 0.040 mg/kg toluene (B 1-60), 0.16 mg/kg ethyl-benzene <br /> (BI-60) and 0.220 mg/kg xylenes (131-60). Hydrocarbons were not detected at normal reporting <br /> limits in sample collected and analyzed from depths between 25 feet and 45 feet bsg, nor between <br /> 65 feet and 70 feet bsg. Hydrocarbons were not detected in samples from boring B2. <br /> No other constituent of concern,including fuel additives,were reported in the soil samples analyzed. <br /> y A summary of soil sample analytical results are presented in Table 1.The laboratory reports for soil <br /> samples (CTEL Project No. CT214-0511197 and CT214-0512111), QA/QC report, and chain-of- <br /> custody form are included in Appendix C. <br /> 1r <br /> 4.3. GROUND WATER ANALYTICAL RESULTS <br /> y <br /> TPH-g and BTEX were not detected in ground water sample collected and analyzed. 1,2-DCA was <br /> detected in the ground water samples collected from borings B 1 and B2 at concentrations of 100µg/l <br /> and 20 gg/1, respectively. Figure 3 displays the 1,2-DCA concentrations at the site. <br /> The domestic well did not have reported detections of any constituents of concern. <br /> Y�1 <br /> No other constituents of concern were detected at or above laboratory detection limits in the ground <br /> water samples analyzed. The analytical results of the ground water samples collected on 05 August <br /> y 2005 are summarized on Table 2. The laboratory report for water samples (CTEL Project No. <br /> CT214-0511194), QA/QC report, and chain-of-custody form are included in Appendix D. <br /> Geotracker upload of the laboratory report electronic deliverable file(EDF)confirmation is included <br /> as Appendix E. <br /> y <br /> 5.0. SUMMARY AND CONCLUSIONS <br /> b. Based on the data collected from the site, AGE finds: <br /> • There were no observable field indications of contamination in any of the soil samples <br /> collected from the soil probe borings. <br /> • The analytical laboratory reported BTEX compounds in two soil samples(131-50 and Bl-60) <br /> at maximum concentrations of 0.026 mg/kg benzene,0.040 mg/kg toluene,0.16 mg/kg ethyl- <br /> Advanced GeoEnvironmental,Inc. <br /> y <br />
