During sampling, the split-spoon was driven ahead of the <br /> auger. The first, or <br /> upper-most,PP t liner was discarded. One <br /> Isample liner was used for geological logging and one waa prepared <br /> �. for shipment to the laboratory for analysis (See Soil and Bedrock <br /> ! ' Logs, Appendix B) . <br /> The upper 2.5 feet in each boring consisted of <br /> r . <br /> 0,3 asphalt/gravel fill. The native soil consisted of brown silt, <br /> 1, clay, and fine sand. In each baring. greyish-green stained soil <br /> F ; <br /> was encountered at a depth of a <br /> P pproxin,ately 25 feet below ground <br /> V! surface down to the capillary fringe; at 50 feet, Petroleum odors <br /> were detected in SB3 from approximately 20 feet down to 50 feet. <br /> In soil borings SB1, SB2 , <br /> �- , SB4 SB5 and SB6 petroleum odors were <br /> encountered from approximately 30 down to 50 feet. E <br /> is <br /> Septic./petroleum odors were datected in each boring from <br /> FA approximately 40 feet down to 50 feet.
