DEPTH <br /> We will be taking core samples using the standard six inch steel sleeve <br /> soil core collector. To ensure maximum reliability, we will take the <br /> sample at the base of the excavations. <br /> Sample 1 is the deepest of the excavations and thus we will take a sample <br /> at the nadir of the excavation at 2 ft. below grade. <br /> Sample 2 is more superficial and thus we will take a sample about a foot <br /> and a half below grade. <br /> Sample 3 was the area specified in the Dames and Moore report as <br /> contaminated. This spill had saturated about six inches of soil that <br /> covered an old concrete road. We have broken up the concrete and will <br /> take the core sample one foot below grade. <br />
