SUMMARY AND CONCLUSIONS <br /> The following conclusions were drawn from the results of this investigation <br /> 1 In general, the site stratigraphy consisted primarily of thick sections of silts and sandy silts <br /> separated by thin layers of silty sands and fine to medium sands to approximately 95 feet bsg <br /> The lithology is dominated by silty sands and medium sands from 100 to 130 feet bsg <br /> (Figure 3) <br /> 1 <br /> iAdvanced GeoEnvironmental,Inc <br /> 1 <br />
