1 <br /> RESNA Industries Inc <br /> Quality Assurance/Quality Control Plan <br /> Revised November 1992 <br /> ' Soil samples will be collected in either 8-ounce widemouth clear glass ,tars provided by the <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 /> ' entails "blind" submittals to the Iaboratory 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 /> 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 /> ' Ten percent of the water samples submitted to the laboratory for analysis will be duplicates. <br /> Water sample duplicates will be created by filling two sample bottles from the well bailer. If <br /> more than one bailer volume is required, each bailer volume will be split between containers. <br /> ' 4.0 SAMPLE PRESERVATION <br /> Sample containers will be pre-cooled and transported to the site in the cooler. All samples will <br /> be preserved as indicated on Table 1 and placed in a cooler immediately after collection <br /> ' Chemical ice sealed in plastic bags will be used in the cooler to cool and maintain samples at <br /> QAQC1092 Favi. 2 <br />
