Smith Environmental Technologies Corporation <br />Quality Assurance/Quality Control Plan <br />Revised February 1995 <br />2.0 SAMPLE CONTAINERS <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 />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 prom -am 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 />m:\..\shellslQAQC-95.WP5 <br />2 <br />• <br />SMTH <br />
