Kennedy/Jenks ons 3 ANALYTICAL RESULTS 31 Soil Sample Analysis The analyses conducted on soil samples collected from Bonngs SB-1 through SB-7, and SB-11 are presented in Table 1 and are summarized below As proposed in the Work Pian, if total recoverable petroleum hydrocarbons (TRPH) were detected m any of the soil samples analyzed, those samples would be analyzed for the following additional compounds « Semivolatile organics compounds (SVOCs) by EPA Method 8270 40 Priority pollutant metals (metals) by EPA Methods 6010 and 7000 TRPH was detected in sod sample SB-1A from Soil Boring SB-1 The analytical reports and associated chain-of-custody forma for the soil samples submitted for analysis are provided in Appendix Q The results are presented in Table 2 for organics and total lead, and Table 3 for inorganics (metals) in Soil Sample SB-1A 3 1.1 Soil Sample Analytical,Results for Petroleum Hydrocarbons Total petroleum hydrocarbons (TPH) as heating ail was detected at concentrations ranging from 6 milligrams per kilogram (mg/kg, or parts per million) to 44 mg/kg in sod samples collected from Borings SB-2, SB-3, SB-4, SB-7, and SB-14 (Table 2) No other petroleum hydrocarbons were detected above laboratory detection limits in the soil samples submitted for analysis from Sod Bonngs SB-2, S13-4, SB-7, and SB-11 TRPH was detected at a concentration of 10 mg/kg in soil sample SB-1A from Boring SB-1 TRPH was not detected above the laboratory detection limit of 10 mg/kg in the soil samples collected from Bonngs SB-4, SB-5, and SB-6 that were submitted for analysis 3.1 2 Soil Sample Analytical Results for Other Organic Constituents Because VOCs were detected in groundwater, those soil samples containing TPN as heating oil or TRPH (Borings SB-1, SB-2, SB-4, S13-7, and SB-11)were analyzed for VOCs by EPA Method 8260 to evaluate the presence of an onsite VOC source As presented in Table 2, VOCs were not detected above the laboratory detection limits As discussed earlier, because TRPH was detected in soil sample SB-1A, the sample was submitted for additional analysis for SVOCs by EPA Method 8270 SVOCs were not detected above the laboratory detection limits 3 1.3 Soil Sample Analytical Results for Metals Total lead concentrations in soil samples ranged from 6 mg/kg to 8 mg/kg These concentrations are well within the range of lead concentrations typically found in U S or Western U S soils (Table 3) Because it may have contained waste oil, one soil sample (SB-1A) was analyzed for the thirteen pnonty pollutant elements These results also show concentrations within the expected range for soil (Table 3) i yObMXN"W70 Mphase-iiAe7R dot 6
