TABLE 1 HISTORICAL SOIL ANALYTICAL RESULTS U.S. Can/Welty Road Vernalis,California Concentrations reported in milligrams per kilogram(mg/kg) Sample Sample Ethyl- Boring ID Depth Sample ID Date TPHg TPHd TPHmo THPc Benzene Toluene benzene Xylenes MTBE VOCs PAHs 6 Samples from B-I thorugh B-7 collected by Radian International LLC,of Walnut Creek,California,and analyzed by American Environmental Network of Pleasant Bill,California,for TPHg, TPHd,and TPHmo using EPA Method 8015M, BTEX using EPA Method 8020,and PAHs using EPA Method 8270. 7 Sample name changed to C035 because C013 was used twice. Sample name C035 was used again on boring B-7. 8 Samples from B-7 through B-9 collected by Radian International and analyzed by Core Laboratories of Anaheim,California,for TPHg,TPHd,and TPHmo using EPA Method 8015M,BTEX and MTBE using EPA Method 8020,and PAHs using EPA Method 8270. A silica gel cleanup was performed on TPHd extracts prior to analysis. 9 Samples collected by Geomatrix Consultants, Inc.,of Oakland, California,and analyzed by Friedman&Bruya of Seattle,Washington. Sample GMX-1 B was analyzed for VOCs using EPA Method 8260. Samples GMX-1B and GMX-2 through GMX-12 were analyzed for TPHc using EPA Method 8015M,BTEX using EPA Method 8021 or EPA Method 8260B,and PAHs using EPA Method 8270 SIM. '0 VOCs were analyzed 8 days past the 14 day hold time. Abbreviations: TPHg=Total petroleum hydrocarbons(TPH)quantified as gasoline. MTBE=Methyl tertiary butyl ether. TPHd=TPH quantified as diesel. TCE=Trichloroethene. TPHc=TPH quantified as crude. 1,1,1-TCA= 1,1,1-Trichloroethane. VOCs=Volatile organice compounds. PAHs=Polynuclear aromatic hydrocarbons. BTEX=Benzene,toluene,ethylbenzene,xylenes. NA=blot Analyzed. ND=Not Detected at or above laboratory reporting limit. Page 0 of 9
