The laboratory soil <br /> samples did not have head space and were inu-nediately sealed in their liners using <br /> aluminum foil lined plastic caps that were taped in place. The samples were then <br /> transferred to an ice chest containing blue ice and transported immediately to Geo- <br /> Analytical Laboratories, a California State certified laboratory, under chain of <br /> custody. <br /> IThe soil samples were analyzed using EPA method GCFID 3550/8015 for total <br /> petroleum hydrocarbons in the gasoline range and EPA method 8020 for volatile <br /> organics including BTX&E. <br /> The excavation was logged (Appendix C) under the direct supervision of a <br /> rregistered geologist using the Unified Soil Classification System. The color, <br /> texture, moisture, plasticity (i£applicable), consistency of the earth materials, <br /> I pertinent soil or bedrock characteristics, and any evidence of contamination was <br /> noted. <br /> 1 <br />
