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/ 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 .
