Page 3 and placed in an iced, insulated container for trans- portation to JL Analytical Services under chain of custody. Subsequent analyses were performed for Total Petroleum Hydrocarbons as Diesel (TPH-D) , Total Petroleum Hydro- carbons as Gasoline (TPH-G) , benzene, toluene, ethyl- benzene, and total xylenes (BTEX) using EPA Methods 3510/ i 8015 and 5030/8015-8020 ( 602 ) , respectively; and for Total Oil and Grease (TOG) using SM 5520 B&F. Certified laboratory analyses of discrete soil and grab water samples from each of the ten borings advanced on site revealed the presence of detectable concentrations of duel hydrocarbon compounds . The results of these analyses are summarized in Tables 1 and 2 • Table 1 Analytical Results of Subsurface Soil Samples Acquired at 275 Grant Line Road, Tracy, CA October, 1993 Sample No. TPH-D TPH-G B T E X TOG and Depth (ppm) (ppm) (ppb) (ppm) • ----------------------------------------------------------- SBR-1@3 ' 28 7 . 4 1 . 7 N D. 9. 6 9 8 360 SBR-1@6' 6 6 N.
