Six to twelve <br /> inches of soil were scraped away from the surface of the stockpile to prepare the soil for <br /> sampling. Samples were then collected from the newly exposed surface. Stockpile samples <br /> were collected in brass tubes and prepared for transport to the laboratory in the same <br /> manner utilized when sampling at the limits of the tank cavity excavation. <br /> x ROUXASSOCiATES 7 Doc#AR06776W.1.1 <br />
