At 10 feet <br /> and 15 feet bsg, red brown, silty fine to medium sand and fine- to medium-grained sand with trace <br /> gravel was identified. <br /> No hydrocarbon odor or organic vapor was detected in any of the soil samples collected from borings <br /> _ P-1 through P-6. Soil boring logs are provided in Appendix A. Geologic cross-section A-A' is <br /> illustrated on Figure 3. <br /> 4.2. ANALYTICAL RESULTS OF SOIL SAMPLES <br /> A total of six soil samples, collected from soil borings P-1 through P-6 at a depth of 10 feet bsg, <br /> were analyzed for the constituents listed in Section 3.2.No target analytes were detected at or above <br /> laboratory detection limits in any of the samples analyzed. Analytical results of soil samples are <br /> summarized in Table 1. The laboratory report (CTEL Project No. CT214-0503209), quality <br /> assurance and quality control (QA/QC) report, and chain of custody forms are included in <br /> Appendix B. <br /> 5.0. SUMMARY AND CONCLUSIONS <br /> Based on the data collected at this site, AGE concludes: <br /> y • In general, red brown, silty fine sand was encountered at 5 feet bsg in all three borings. At <br /> 10 feet and 15 feet bsg, red brown, silty fine to medium sand and fine- to medium-grained <br /> _ sand with trace gravel was identified. <br /> • A total of six soil samples, collected from soil borings P-1 through P-6 at 10 feet bsg, were <br /> analyzed for the constituents listed in Section 3.2. No target analytes were detected at or <br /> above laboratory detection limits in any of the samples analyzed. <br /> 6.0. RECOMMENDATIONS <br /> Based on information collected during this investigation, no further action or environmental <br /> investigation is warranted at this time. <br /> Advanced GeoEvironmental,Inc. <br />
