I <br /> I01 November 2005 <br /> AGE-NC Project No 02-0950 <br />' Page 8 of 9 <br />' 33 ANALYTICAL RESULTS OF SOIL SAMPLES <br /> A total of sixteen soil samples were collected from borings B5,B6,MW-4,and MW-5 and analyzed <br /> I for the constituents listed in Section 2 12 No petroleum hydrocarbon constituents were detected at <br /> or above laboratory reporting limits in the soil samples analyzed Analytical results of soil samples <br /> are summarized in Table 1 The laboratory reports(CTEL Project Nos CT214-0507111,-0507158, <br /> I and -0507142), quality assurance/quality control (QA/QC) reports, and chain of custody forms are <br /> included in Appendix F <br /> I3 4 ANALYTICAL RESULTS OF GRAB GROUND WATER SAMPLES <br />' A total of five grab ground water samples were collected from borings B5, B6, and CPT-1 and <br /> submitted for laboratory analysis for the constituents listed in Section 2 1 2 TPH-d was detected in <br /> sample B5-W, collected between 20 feet and 30 feet bsg, at a concentration of 19,000 micrograms <br /> Iper liter(µg/1) <br /> No additional petroleum hydrocarbon constituents were detected at or above laboratory reporting <br /> limits in the grab ground water samples analyzed The laboratory reports (CTEL Project Nos <br /> CT214-0507111,-0507158,and-7120),QA/QC reports,and chain of custody forms are included in <br /> Appendix F Analytical results for the grab ground water samples are summarized in Table 2 <br /> I3 5 GEOTRACKER CONFIRMATIONS <br /> Documents confirming the upload of laboratory electronic deliverable format(EDF)files and depth <br /> Ito water measurements to GeoTracker are included in Appendix G <br />' 4.0. SUMMARY AND CONCLUSIONS <br /> Based upon the findings of this investigation, AGE concludes <br /> IIn general,silty clay and clayey silt,with lesser,discontinuous layers of sandy material, were <br /> encountered from surface grade to approximately 23 feet to 25 feet bsg From between <br /> 23 feet and 25 feet to approximately 29 feet bsg, silty sand and fine-to coarse-grained sand <br /> was identified, grain size appeared to increase with depth From 29 feet to approximately <br /> 67 feet bsg, silty clay and clayey silt were encountered, with a thin, discontinuous layer of <br /> Isandy material encountered at approximately 34 feet bsg in borings MW-4 and MW-5,a thin <br /> layer of sandy sediments and stiff, fine-grained material was encountered at approximately <br /> Advanced GcoEnvironmental,Inc <br /> I <br />
