ij <br />} <br /> ATC Associates Inc. <br /> Quality Assurance/Quality Control Plan <br /> Revised 1998 <br /> I� <br /> i <br /> 2.0 SAMPLE CONTAINERS '1 <br /> Groundwater samples will be placed in containers supplied by the analytical laboratory. Table l <br /> summarizes the required sample containers. 3 <br /> s • <br /> E <br />{ Soil samples will be collected in either 8-ounce widemouth clew glass jars provided by the laboratory <br /> or in clean brass or stainless steel tubes (Table 1). Screw on caps will be fitted with teflon liners. <br /> Tubes will be tightly capped and sealed. <br /> a 3.0 QUALITY CONTROL FIELD SAMPLES <br /> I� <br /> A QC program independent from the Iaboratory's program will be instituted. The program entails <br /> "blind" submittals to the laboratory of blank and duplicate samples. No spiked samples will be supplied <br /> from the field for this investigation. The laboratory in-house QC program will include analysis of <br /> I spiked samples. All QC samples will be assigned independent; sample numbers and made <br /> indistinguishable from non-QC samples. <br /> When sampling groundwater, travel blanks will be used to detect the introduction of contaminants <br /> I <br /> during transportation from the field to the laboratory. The travel blanks will be provided by the <br /> ij <br /> analytical laboratory. They will be taken to the field and accompany the collected groundwater <br /> samples to the laboratory for analysis. The blanks will consist of deionized water and analytically <br /> confirmed organic-free water. The blank is numbered, packaged, and sealed in the same manner as the <br /> other samples. <br /> Ten percent of the water samples submitted to the laboratory for analysis will be duplicates. Water <br /> sample duplicates will be created by filling two sample bottles from the well bailer. If more than one <br /> bailer volume is required, each bailer volume will be split between containers. <br /> i <br /> 2 <br /> 'i <br />
