A limited site inspection was <br /> conducted that revealed ten piles of soil each containing approximately 50 yards <br /> of soil.

The samples <br /> were collected by driving a 1.5 inch diameter brass tubes into undisturbed soil <br /> and sealing the tubes with foil and a plastic cap. The tubes were labeled <br /> . accordingly and placed in a cooler containing blue ice for transport to the <br /> analytical laboratory.
