Records Center UST Closure In-Place and Soil Sampling Report <br /> April 20,2012 <br /> Page-4- <br /> for the requested EPA Method 8080 analysis. The Laboratory indicated that EPA Method 8082A is the <br /> more up to date version of EPA Method 8080 and is otherwise equivalent. <br /> 9.0 LABORATORY ANALYTIC AL RESULTS <br /> Laboratory analyses indicate that TP -G, TPH-D, BTEX, MTBE, TBA, DIPE, ETBE, TAME, 1,2-DCA, <br /> EDB, chlorinated hydrocarbons, cadmium, and Chromium VI were not detected at or above the <br /> laboratory reported detection limits in the soil samples collected from below the UST. Chromium III, <br /> lead, zinc, and nickel were detected n the four soil samples collected from below the UST. Lead was <br /> detected in sample W-10 at a concentration of 140 milligrams per kilogram (mg/kg). PCB-1254 was <br /> detected in sample W-8 at a concentration of 0.093 mg/kg or 93 parts per billion (ppb). Sample W-8 was <br /> collected at approximately two feet below the bottom of the west end of the tank. <br /> The laboratory analytical results of tl a soil samples are presented in Table 1. The laboratory analytical <br /> results of the soil samples collected o i March 29, 2012 are also presented with the results from the May <br /> 5, 2011 investigation on Figure 5, All endix A. Laboratory analytical reports and a copy of the chain-of- <br /> custody record for the soil samples art included in Appendix B. <br /> Table 1 Soil Sam le Laborato Anal tical Results March 29,2012 <br /> Sample I.D. 5960B-W-8 596013-E-8 596013-E-10 5960B-W-10 <br /> Anal e EPA Method units <br /> TPH-G 8015M m <1.0 <1.0 <I.0 <1.0 <br /> TPH-D 8015M m <5.0 <5.0 <5.0 <5.0 <br /> Benzene 8260B mg/kg <0.005 <0.005 <0.0d5 <0.005 <br /> Toluene8260B m g <0.005 <0.005 <0.005 <0.005 <br /> Ethyl Benzene 826013 m <0.005 <0.005 <0.005 <0.005 <br /> Total Xylenes 8260B m /kp <0.005 <0.005 <0.005 <0.005 <br /> MTBE 8260B m <0.005 <0.005 <0.005 <0.005 <br /> TBA 8260B or <0.050 <0.050 <0.050 <0.056 <br /> 1� 1 DIPE 8260B m <0.005 <0.005 <0.005 <0.005 <br /> ETBE 8260B m <0.005 <0.005 <0.005 <0.005 <br /> TAME 826013 m <0.005 <0.005 <0.005 <0.005 <br /> 1,2 DCA 8260B In <0.005 <0.005 <0.005 <0.005 <br /> EDB 8260B m <0.005 <0.005 <0.005 <0.005 <br /> Chlorinated <0.005- <0.005- <0.005- <0.005- <br /> Hydrocarbons 8260B m g <0.050 <0.050 <0.050 <0.050 <br /> Cadmium 7420 To <1.0 <1.0 <1.0 <1.0 <br /> Chromium III 7420 m 20 19 16 10 <br /> Lead 7420 m 17 16 25 140 <br /> Zinc 7420 m 45 35 22 20 <br /> Nickel 7420 m 14 14 13 12 <br /> Chromium VI 7199 m <0.50 <00 <050 <0.50 <br /> PCBs 8080 m 0.093 <0.025 <0.025 <0.025 <br /> Unit Conversions: <br /> mg/kg=milligrams per kilogram=parts per million(ppm). <br /> Analytical <br /> TPH-G=total petroleum hydrocarbons,quanti ied as gasoline.TPH-D=total petroleum hydrocarbons,quantified as Diesel. <br /> MTBE = methyl tertiary-butyl ether.
