11 <br />ATTACHMENT A <br />FIELD AND LABORATORY PROCEDURES <br />Attachment A <br />Field and Laboratory Procedures <br />Soil Sampling <br />Soil samples were collected by advancing 2 -inch -diameter brass sample liners into soil removed from an <br />excavation by a backhoe bucket. Soil samples for chemical analysis were retained in the brass liners, <br />labeled, and capped with Teflon sheets and plastic end caps. The samples were then sealed in zip -lock <br />bags, placed on ice, and transported to the laboratory accompanied by the appropriate chain -of -custody <br />documentation. <br />Soil Sampling from Stockpiled Soil <br />Soil samples were collected by advancing 2 -inch diameter brass sample liners into the soil stockpile, after <br />removing approximately 6 inches to 1 foot of surface material in the sample location. One composite <br />sample (four sleeves to 1 sample) was collected per approximately 100 cubic yards of soil. Soil samples <br />for chemical analysis were retained in the brass liners, labeled, and capped with Teflon sheets and plastic <br />end caps. The samples were then sealed in zip -lock bags, placed on ice, and transported to the laboratory <br />accompanied by the appropriate chain -of -custody documentation. <br />Laboratory Analysis of Soil Samples <br />Soil samples were analyzed for purgable hydrocarbons, BTEX, MTBE, TBA, DIPE, ETBE, TAME, and total lead. <br />Stockpiled soil samples were analyzed for purgable hydrocarbons, BTEX, and total lead. <br />
