<br /> Notes:
<br /> 1 Sample S-6 collected by ERM-West,Inc.of Walnut Creek, California,and analyzed by Sequoia Analytical of Walnut Creek,California,for VOCs using EPA Method 8240.
<br /> Sample S-6 at 0.5 R depth also contained 3900 mg/kg TPH quantified as oil and grease and 14 mg/kg lead.
<br /> 2 Samples designated"HB"collected by ERM-West, Inc.,of Walnut Creek,California. Complete analytical laboratory data and analytical methods used were not available.
<br /> 3 Sample collected by WHF,Inc.,of Oakdale,California,and analyzed by California Laboratory Services of Rancho Cordova,California, for TPHd and TPHmo using EPA
<br /> Method 8015M,and VOCs using EPA Method 8010/8020.
<br /> ° Sample MW-1 collected by Geological Technics,Inc.,of Modesto,California,and analyzed by Sherwood Labs Corp.of Hilmar,California, for TPHg,.TPHd,and TPHmo
<br /> using EPA Method 8015, and BTEX using EPA Method 8020;and by Entech Analytical Labs, Inc.of Sunnyvale, California,for VOCs using EPA Method 8240.
<br /> 5 Results reported as EPA Method 8020/EPA Method 8240.
<br /> 6 Samples from B-I through B-7collected by Radian International LLC,of Walnut Creek,California,and analyzed by American Environmental Network of Pleasant Hill,
<br /> California,for TPHg,TPHd,and TPHmo using EPA Method 8015M,BTEX using EPA Method 8020,and PAHs using EPA Method 8270.
<br /> Sample name changed to C035 because C013 was used twice. Sample name C035 was used again on boring B-7.
<br /> 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
<br /> 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.
<br /> 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
<br /> VOCs using EPA Method 8260. Samples GMX-1 B and GMX-2 through GMX-12 were analyzed for TPHc using EPA Method 8015M,BTEX using EPA Method 8021 or
<br /> EPA Method 8260B, and PAHs using EPA Method 8270 SIM.
<br /> 10 VOCs were analyzed 8 days past the 14 day hold time.
<br /> Abbreviations:
<br /> TPHg=Total petroleum hydrocarbons(TPH)quantified as gasoline. MTBE=Methyl tertiary butyl ether.
<br /> TPHd=TPH quantified as diesel. TCE=Trichloroethene.
<br /> TPHc=TPH quantified as crude oil. 1,1,1-TCA= 1,1,1-Trichloroethane
<br /> VOCs=Volatile organic compounds. PAHs=Polynuclear aromatic hydrocarbons.
<br /> BTEX=Benzene,toluene,ethylbenzene,xylenes. NA=Not Analyzed
<br /> ND=Not Detected at or above laboratory reporting limit.
