At <br /> 1 <br /> Smith Technology Corporation <br /> Quality AssurancelQuality Control Plan <br /> Revised February 1995 <br /> i <br /> 2.0 SAMPLE CONTAINERS <br /> I <br /> Groundwater samples will be placed in containers supplied by the analytical laboratory. Table 1 <br /> summarizes the required sample containers. ` <br /> Soil samples will be collected in either 8-ounce widemouth clear 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 /> i <br /> 3.0 QUALITY CONTROL FIELD SAMPLES <br /> A QC program independent from the laboratory'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 /> 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 /> during transportation from the field to the laboratory. The travel .blanks will be provided by the <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 /> I <br /> I <br /> I <br /> I <br /> I <br /> W A1AdminlShells\QAQC-97.DOC <br /> 2 <br /> i <br />� M <br /> k <br />
