The servicp rtt,ltion fneludes a building, two <br /> underground fuel storage tanks to the nortlicaat of the building, two pump <br /> islands to the east of the building, interconner;,_-ng piping, and a waste <br /> Oil tank at the southwest corner of is+ei� _ ,Lands- access for drilling <br /> is restricted due to the presence Of offsite buildings, onsite <br /> buildings/structures, and public roods (Pacific Avenue). The site is <br /> generally flat with asphalt concrete and concrete overly. <br /> 3.2 SOIL SAMPLING <br /> Five soil borings (B-1 through 5) were advanced during this preliminary <br /> (Phase 1) investigation. A .facilities and soil. boring location map is <br /> provided as Plate 2. The boring logs (Plates 4-9) are attached as <br /> Appendix B. <br /> one soil boring (B-1) was advanced to the north of the underground fuel <br /> w tanks. A second boring (B--2) was placed to the east of these tanks. A <br /> third boring (B-3) was advanced between the underground tanks and the pump <br /> islands just to the south. The fourth boring (B-4) was placed adjacent to <br /> the waste oil tank. The final boring (B-5) was advanced south of the east <br /> Pump island. <br /> Soil borings were advanced using a truck-mounted drill rig equipped with a <br /> 6-inch hollow stem auger. An experienced environmental geologist logged <br /> the boreholes screened--the---soils ant-collected soil samples for later T <br /> analysis. To minimize cross contamination, all augers and associated <br /> equipment were steam cleaned prior to the drilling of each borehole. In <br /> 85--88-219 3 <br />
