V w. <br /> v� <br /> 1 <br /> MEWED <br /> 00 <br /> i <br /> Soil samples will be collected in either 8--once widemouth <br /> clear glass jars provided by the laboratory <br /> brass or stainless steel tubes (Table 1 °= iScrew o ccaps <br /> will be fitted with teflon liners. Tubes willbe tightly <br /> capped and sealed. <br /> 3.0 Quality Control Field Samples <br /> beQi stitprogrutedhe independent efrom the laboratory's Program will <br /> the laboratory program entails blind submittals to <br /> ry oa blank and duplicate samples. No spiked <br /> samples will be supplied from the field for this <br /> investigation. The laboratory in-house QC program will <br /> include analysis Of spiked samples. All QC samples will be <br /> assigned independent sample numbers and made <br /> indistinguishable from non QC samples. <br /> Wher-. sampling groundwater, travel blanks will be used to <br /> detect the introduction of contaminants during <br /> transportation from the field to the laboratory. The travel <br /> blanks will be provided by the analytical laborato <br /> ry. They <br /> will be taken to the field and accompany the ollected <br /> groundwater samples to the laboratory for analysis. The <br /> blanks will consist of deionized water and analytically <br /> confirmed organic-free water. The blank is numbered, <br /> packaged, and sealed in the same manner as the other <br /> samples. <br /> Tea percent of the water samples submitted to the laboratory <br /> for analysis will, be duplicates. Water sampla duplicates <br /> will be created by filling two sample bottles from the well <br /> bailer. If more than one bailer volume is required, each <br /> bailer volume will be split between containers. <br /> 4.0 Sample Preservation <br /> Sample containers will be pre-cooled and transported to the <br /> site in the Cooler. All., samples will be preserved as <br /> Indicated on Table 1 and placed in a cooler immediately <br /> after collection. Chemical ice sealed inplastic bags will <br /> be used in the cooler to cool and maintain samplep at a <br /> temperature of 40c. A high-low thermometer will accompany <br /> the samples to document transport conditions. Further <br /> discussion of samples preservation is included in the <br /> sampling protocols (Sections 11 and 12). <br /> 5.0 Chain-Of-Custod <br /> y-pr°cedures - <br /> 5.1 Sample Labels <br /> Each sample container will be labeled prior to filling to <br /> prevent misidentification. The label will contain at least <br /> the following .information: <br /> Sample number which uniqualy identifies the sample <br />
