a <br /> t d <br /> Soil samples will be collected in either a-once widemouth <br /> clear glass jars provided by the laboratory or in clean <br /> brass or stainless steel tubes (Table 1 ). Screw on caps <br /> will be fitted with teflon liners. Tubes will be tightly <br /> capped and sealed. <br /> 3.0 Quality Control Field Samples <br /> A QC program independent from the laboratory's program will <br /> be instituted. The program entails "blind" submittals to <br /> the laboratory of 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 /> When sampling grour_dwater, 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 laboratory. They <br /> will be taken to the field and accompany the collected <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 /> Ten percent of the water samples submitted to the laboratory <br /> for analysis will be duplicates. Mater sample 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 in plastic bags will <br /> be used in the cooler to cool and maintain samples at a <br /> temperature of 4°C. 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-Custody Procedures <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 uniquely identifies the sample <br />
