*kw� ,,O <br /> Di Salvo Track Lines-SIR <br /> March 9,1995 <br /> V <br /> Page fi- <br /> samples were analyzed for benzene, toluene, ethyl benzene, and xylene (BTEX) by EPA Method 8020, <br /> L <br /> and for total extractable petroleum hydrocarbons, quantified as kerosene, diesel and motor oil (TEPH) <br /> L by Method 3550/LUFT. The groundwater samples were analyzed for BTEX by EPA Method 602 and <br /> for TEPH by Method 3510/LUFT. Laboratory report sheets indicating analytical methods used, <br /> detection limits, and results of analyses are presented in Appendix C. <br /> L <br /> 5.0 RESULTS OF ANALYSES <br /> L Laboratory analyses of soil samples SP2-6 and SP2-12 detected TEX constituents at <br /> concentrations ranging from 150 gg/kg to 320 µg/kg and diesel at concentrations ranging from 1,600 <br /> it mg/kg to 5,800 mg/kg. The reported laboratory detection limits for BTEX constituents and TEPH <br /> were raised in SP2 because of high hydrocarbon concentrations detected in the soil samples collected <br /> L, from SP2. Benzene, kerosene and motor oil were not detected in SP2-6 and SP2-12 at or above the <br /> reported laboratory detection limits. Diesel was detected in SP3-6, S133-12, SP4-6 and SP4-12 at <br /> ` concentrations ranging from 5.8 mg/kg to 16 mg/kg. BTEX constituents, kerosene and motor oil were <br /> not detected at or above the reported laboratory detection limits in the soil samples collected from SP3 <br /> L and SP4. No evidence of hydrocarbon contamination was detected at or above the reported laboratory <br /> detection limits in the soil samples collected from SP1. <br /> L <br /> Laboratory analyses of groundwater samples collected from SP2 and SP4 detected BTEX <br /> Lconstituents at concentrations ranging from ND to 5.0 µg/1 and diesel at concentrations ranging from <br /> 350 mg/l to 520 mg/l. Diesel was detected in SPI at a concentration of 18 mg/l. The laboratory <br /> ` detection limits requested by SJCPHS,EHD, on the day of field work, were raised because of elevated <br /> hydrocarbon concentrations in the groundwater samples. Kerosene and motor oil were not detected <br /> at or above the reported laboratory detection limits in SP1, SP2 and SP4 and BTEX constituents were <br /> not detected in SP1. BTEX constituents were not detected in the trip blank at or above the reported <br /> laboratory detection limits. Results of laboratory analyses are presented in Table 1. <br /> r <br /> L: CONDOR <br />
