U <br /> GSI Field Methods and Procedures <br /> Updated August 12, 1994 - <br /> Page 3 <br /> Each discrete stockpile sample is collected by removing the upper 3 to 6 inches <br /> of soil, and them driving the stainless steel or brass sample tube into the <br /> stockpiled material with a hand, mallet, or drive sampler. The sampleaubes are <br /> then covered on both ends with teflon sheeting or aluminum foil, capped, labeled, <br /> and placed in a cooler with blue ice for preservation. A chain-of-custody form is <br /> initiated in the field and accompanies the selected soil samples to the'analytical <br /> laboratory. Stockpiled soils are covered with plastic sheeting after completion of <br /> sampling. <br /> i <br /> ; <br /> GeoStrategies Inc. <br />
