4 <br /> 3.2 Laboratory Analyses <br /> The soil samples collected from beneath the fuel dispensers (labeled D1 through D9) and product <br /> piping(labeled P1 through P5)were analyzed for total petroleum hydrocarbons modified for diesel <br /> (TPH-d) in general accordance with EPA Method 8015M. In addition, the soil samples collected <br /> from beneath the fuel dispensers and product piping were analyzed for benzene, toluene, <br /> ethylbenzene, total xylenes (BTEX) and fuel oxygenates in general accordance with EPA Method <br /> 8260B. <br /> Selectedsoilsamplescollectedfrombeneaththefueldispensers(D4throughD6)andproductpiping <br /> (PI through P4)were also analyzed for total petroleum hydrocarbons modified for gasoline(TPH-g) <br /> in general accordance with EPA Method No. 8015M. <br /> The soil sample collected from beneath the oil dispenser (01) was analyzed for total recoverable <br /> petroleum hydrocarbons (TRPH) in general accordance with EPA Method No.418.1. Soil sample <br /> 01 was also analyzed for BTEX and fuel oxygenates in general accordance with EPA Method <br /> 8260B. <br /> 3.3 Soil Sample Results <br /> TPH-d was detected in soil samples D2, D5, D8 and D9 at concentrations ranging from 220 <br /> milligrams per kilogram(mg/kg)to 2,300 mg/kg. Soil samples D2,D5 and D8 were collected from <br /> beneath the center fuel dispensing island. Soil sample D9 was collected from beneath the western <br /> ' dispenser on the southern island. <br /> TPH-g was detected only in soil sample D5 at a concentration of 28 mg/kg. The remaining soil <br /> samples analyzed for TPH-g(134,D6,and P 1 through P4)did not contain concentrations of TPH-g. <br /> BTEX and fuel oxygenates were not detected in soil samples collected as part of this investigation <br /> with the exception of D5 and D9 which contained concentrations of total xylenes of 0.78 mg/kg and <br /> 1.3 mg/kg,respectively. <br /> ' Soil sample laboratory analytical results have been summarized in Table 1. Soil samples were <br /> analyzed by Baseline On-Site Analysis, a State-certified hazardous waste testing laboratory based <br /> ' in Huntington Beach, California. The laboratory and quality control reports, along with chain-of- <br /> custody documentation, are provided in Appendix A. <br /> ' FREY <br />
