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 <br /> 3 <br /> laboratory or in clean brass or stainless steel tubes (Table 1). Screw on caps will be fitted with ' <br /> teflon liners. Tubes will be tightly capped and sealed. <br /> 3.0 QUALITY CONTROL FIELD SAMPLES <br /> A QC program independent from the laboratory's program will be instituted. The program <br /> i <br /> entails "blind submittals to the laboratory of blank and duplicate samples. No spiked samples <br /> will be supplied from the field for this investigation. The laboratory in-house QC program will <br /> include analysis of spiked samples: All QC samples will be assigned independent sample <br /> numbers and made indistinguishable from non-QC samples. <br /> i <br /> When sampling groundwater, travel blanks will be used to detect the introduction of <br /> contaminants during transportation from the field to the laboratory. The travel blanks will be <br /> provided by the analytical laboratory. They will be taken to the field and accompany the <br /> collected groundwater samples to the laboratory for analysis. The blanks will consist of <br /> deionized water and analytically confirmed organic-free water. The blank is numbered, <br /> packaged, and'sealed in the same manner as the other samples. <br /> i <br /> W:\Adrnin\Shelis\QAQC-98.DOC <br /> i <br /> 2 <br />
