FINDINGS <br /> Ground water was encountered at a depth of approximately 40 feet bsg in soil boring MW-7 and t <br /> MW-8 <br /> i <br /> E <br /> ,y I <br /> 31 STRATIGRAPHY <br /> 1 <br /> East'of the former UST, gray to green silt was encountered from surface grade to depths of <br />' approximately 55 feet bsg A gray silty sand was encountered between 55 feet and 65 feet bsg Silty <br /> clay was encounter between 60 feet bsg to 80 feet bsg A gray silt was encountered at the total depth <br /> of the soil boring at a depth of 80 feet bsg Soil boring logs for the soil interval between the 45 feet <br />' and 80 feet bsg are shown in Appendix A Water was encountered in borings at approximately 40 <br /> feet bsg <br />' 3 2 ANALYTICAL RESULTS OF SOIL SAMPLES <br /> A total of four soil samples from MW-7 were analyzed for TPH-g, BTEX and MTBE and the suite <br /> of five fuel additives by EPA Method 8260 Modified Analytical concentrations in the soil samples <br /> were below laboratory reporting limits for all the analytes tested I <br /> Analytical results for soil samples analyzed by EPA Methods 8015 Modif ed and 8020 are <br /> summarized in Table 1 Analytical results for the ground water samples as analyzed by EPA Method <br /> 8260 Modified are summarized in Table 2 The laboratory report (MAI Laboratory I D Nos 29031 <br /> through 29034), quality assurance and quality control (QA/QC) report and,chain-of-custody form <br /> I <br /> are included in Appendix B <br /> 1 <br /> 4.0. CONCLUSIONS t <br /> Based on data collected from the site, AGE concludes s <br /> 1 <br /> • No soil contamination was observed in the soil borings established for well MW-7 Wells <br /> MW-7 and MW-8 are located in the apparent down-gradient direction from well MW-6 <br /> Advanced Geo Environmental,Inc <br /> I r L I <br /> + r I F I 1 1 <br /> 1 I1 1 <br />
