Soil sample from one and five feet below <br /> S02-5' surface near the trench <br /> (trench) 2.

SOIL CLASSIFICATION SYSTEM <br /> A registered geologist will be on site to work with the drilling crew, handle <br /> samples, and prepare drill logs. Logs will include descriptions of the depths and <br /> types of soil encountered and notes on indications of contamination. The Unified <br /> Soil Classification System with visual-manual procedures (ASTM D 2488-84) <br /> will be used for soil description. The registered geologist will certify the <br /> findings. <br /> 2. SOIL SAMPLING METHOD <br /> Soil samples will be obtained using an 18-inch long modified California split- <br /> spoon sampler containing new, 2-inch diameter brass liners. The ends of the soil <br /> Iiners retained for consideration for subsequent laboratory analysis will be sealed <br /> with Teflon sheets, and end caps will be taped. The liners will then be <br /> individually labeled and placed on ice or refrigerated for preservation until <br /> delivery to the analytical laboratory. Standard chain-of-custody procedures will <br /> he implemented in the field to document soil sample collection, handling, and <br /> analytical requests. <br /> • <br /> 5 <br /> ERICKSON, Inc. <br /> Specialized Service to Industry Since 1942 <br />
