Results of the field investigation and laboratory testing are summarized in the following <br /> subsections. <br /> 5.1 Soil Profile: The soil profile beneath the site consisted of strata of: well graded, fine <br /> to very coarse grain, silty sand with clay, and slightly plastic clay to a depth of 48 feet BSG, <br /> the greatest depth explored. Descriptions of the conditions encountered in the soil borings <br /> are presented in the logs of soil borings (Appendix Q. <br /> The foregoing is a general summary of the subsurface conditions encountered in the soil <br /> borings drilled for this investigation. Stratification lines on the soil boring logs represent <br /> approximate boundaries between soil types. Actual transitions between soil types may be <br /> gradual, and the interpretation of various soil types from soil cuttings is subjective. <br /> 5.2 Results of Field Screening: The results of the field screening with the PID are <br /> summarized in Table 2. <br />{ L <br /> TABLE'2 <br /> Summary of:PID Field Screening Results . <br /> Sample F ocation, .
