FINDINGS <br /> Results of field observations and laboratory analysis of soil and ground water samples are reported <br />' and discussed In the following sections <br /> 3 1 SOIL PROFILE - <br />' Generally, interbedded pale brown to graylbrown, silty sands and silty clays/clayey silts were <br /> encountered between surface grade and 25 feet bsg A dark blue/gray to gray,medium dense,slightly <br /> silty, fine to medium sand was generally encountered from 25 feet bsg to 35 feet bsg A dark <br /> blue/gray to gray, firm to very stiff, silty clay/clayey silt was generally encountered at depths <br /> between 35 feet and 45 feet bsg A dark blue/gray, medium dense, fine to medium sand was <br /> generally encountered at depths between 45 feet and 50 feet bsg A dark blue/gray to gray, firm to <br />' very stiff, silty clay/clayey silt was generally encountered at depths In excess of 50 feet bsg <br /> Saturated soil was encountered from boring MW-4 between 20 and 25 feet bsg and from borings <br />' MW-5, MW-6 and MW-7 between 25 and 30 feet bsg An unidentified faint to intense odor was <br /> noted In soil sample duplicates collected from soil boring's MW-4 at depths between 20 feet and 55 <br /> feet bsg, from MW-6 at depths between 30 and 40 feet bsg and from MW-7 at 40 foot bsg Each <br />' sample that contained the unidentified odor was noted on boring logs as having a dark blue color, <br /> organic, and non-detect utilizing a PID meter (lacking hydrocarbons) Boring logs are included In <br />' Appendix A General Inthology beneath the site In cross sectional view is depicted In Figures 3 and <br /> 4 <br /> 1 <br /> Advanced GmEnviranmental,Inc <br />
