electrical/duct tape. Each tube was then labeled and placed <br /> on blue ice pending transportation to California State Department <br /> of Health Services Certified Hazardous Waste Laboratory #E694 . <br /> Analyses were subsequently conducted for Total Petroleum <br /> Hydrocarbons as Gasoline (TPH-G) , benzene, toluene, total <br /> xylenes, and ethylbenzene (BTX&E) using EPA Methods 5030/8015- <br /> 8020; and Total Petroleum Hydrocarbons as Diesel (TPH-D) using <br /> EPA Methods 3550/8015. <br /> Soil boring SB-1 was advanced to a depth of 30. 5 feet bgs. . . <br /> encountering a brown silty sand between 0.0 ' and 3 . 5 ' bgs; a <br /> brown, yellow clayey sand between 3 .5 ' and 13 . 5 ' bgs; a brown <br /> sandy clay between 13 . 5 ' and 25 . 0 ' bgs; brown clayey sand 25. 0 ' - <br /> 27.01 ; and a yellow, brown sandy clay 27. 0 ' -30.5 ' bgs . Ground- <br /> water was encountered at approximately 30 . 0 ' bgs . No hydrocarbon <br /> odors were encountered within SB-1 . <br /> Soil boring SB-2 was advanced to a depth of 30. 5 ' bgs and <br /> encountered a yellow, brown silty sand between 0.0 ' and 17. 0 ' <br /> bgs; a brown clayey sand 17. 0 ' -22. 0 ' bgs; brown sandy clay 22.0 '- <br /> 27.0 ' bgs ; and a gray clayey sand between 27. 0 ' and 30 . 5 ' bgs. <br /> Groundwater was encountered at approximately 30. 0 ' bgs. No <br /> hydrocarbon odors were encountered within SB-2. <br /> Soil boring SB-3 was advanced to a depth of 20 .5 ' bgs. Soils <br /> encountered consisted of a yellow, brown silty sand between <br /> 0. 0 ' and 14 . 0 ' bgs. This soil was free of hydrocarbon odors. , <br /> A brown clayey sand (moist,- medium, and dense) was encountAred <br /> between 14 .0 ' and 18. 5 ' bgs. This soil was discolored and <br /> contained a strong hydrocarbon odor. A yellow silty sand, which <br /> was free of hydrocarbon odors, was present between 18,5 ' and <br /> 20.0 ' bgs . A brown clayey sand (very moist and densd) was <br /> encountered between 20. 0 ' and 20 . 5 ' bgs. This soil was also <br /># discolored and contained a strong hydrocarbon odor., Boring <br /> SB-3 was terminated prior to reaching groundwater ,to avoid <br /> introducing contaminants into the water. All borings were <br /> backfilled with cement to the bottom of the existing pavement <br /> and then sealed with cold asphalt patch. <br /> A description of the soil borings is attached hereto as Appendix <br /> "A"; while copies of laboratory reports of certified analyses <br /> are attached as Appendix "B". As indicated, these analyses <br /> revealed soil contamination within boring SB-3 as referenced <br /> within Chart II: <br /> CHART II <br /> Analyte _ _ Matrix/Depth bgs Concentration <br /> TPH-G Soil/15 .0 ' 1400 ppm <br /> TPH-G Soil/20 . 0 ' 1200 ppm <br /> 6. <br />
