Laboratory Chemical Analysis <br /> A total of eight (8) soil samples were collected from the five (5) soil borings. Two (2) soil <br /> samples were collected from each borehole except for boring B-2 due to drilling refusal. No <br /> groundwater was encountered in any of the borings advanced. <br /> All soil and samples collected were analyzed for total petroleum hydrocarbons (TPH)as gasoline <br /> (g), TPH as diesel (d), TPH as motor oil (mo), using Environmental Protection Agency (EPA) <br /> Test Method 8015. In addition, five (5) soil samples were also analyzed for volatile organic <br /> compounds (VOC's) including benzene,toluene, ethyl benzene, and xylenes (BTEX) methyl tert <br /> Buytl ether (MTBE) and chlorinated solvents using (EPA) Test Method 8260. Sample analysis <br /> was performed by McCampbell Analytical LLC, of Pittsburg, CA. The laboratory chemical <br /> results are tabulated in Tables 1, 2 and 3, and the laboratory analytical report including the <br /> Chain-of-Custody documentation is attached in Appendix A. <br /> Table 1: Soil Sample Analytical Results <br /> Date Samle ID g <br /> p TPH- TPH-d TPH-mo B T E X Additional <br /> VOC's <br /> -------------m-/Kg---------- <br /> 13-1-8' <1.0 <1.0 <5.0 <0.0050 <0.0050 <0.0050 <0.0050 ND <br /> 13-1-20' I.n 1.0 <5.0 <0.0050 <0.0050 <0.0050 <0.0050 ND <br /> 12-10-14 <br /> B-3-9' <1.0 <1.0 <5.0 <0.0050 <0.0050 <0.0050 <0.0050 ND <br /> B-3-20' <1.0 1.7* <5.0 <0.0050 <0.0050 <0.0050 <0.0050 ND <br /> B-4-10' <1.0 <I.0 <5.0 <0.0050 <0.0050 <0.0050 <0.0050 ND <br /> B-4-20' <1.0 <1.0 <5.0 <0.0050 <0.0050 <0.0050 <0.0050 ND <br /> 13-5-12' <1.0 <1.0 <5.0 <0.0050 <0.0050 <0.0050 <0.0050 ND <br /> 13-5-20' <1.0 1.0 <5.0 <0.0050 <0.0050 <0.0050 <0.0050 ND <br /> <1.0 = Less than the laboratory reporting limit. <br /> ND =Non-detect <br /> * = Diesel range compounds are significant;no recognizable pattern. <br /> 5 <br />
