4.o SAMPLE HANDLING <br /> 4.1 SAMPLE CONTAINERS, IDENTIFICATION AND LABELING <br /> 4.1.1 Sample Containers <br /> Soil samples for laboratory analysis will be collected in stainless steel or <br /> brass liners. The liners will have the ends covered with Teflon film <br /> and plastic caps. <br /> If a well point is used, groundwater samples will be collected in a <br /> Teflon bailer. Water will be immediately transferred to an appropriate <br /> sample bottle. <br /> 4.1.2 Sample Identification <br /> Sample identification numbers will follow the labeling conventions <br /> discussed in the workplan. <br /> 4.1.3 Sample Labeling <br /> All samples will have a plastic or waterproof paper label (Figure 1) <br /> attached which will be filled out using waterproof ink. The label will <br /> contain the following information: <br /> • Project number. <br /> • Site/Project name. <br /> Sample number. <br /> Boring number and depth. <br /> Sampler's name. <br /> • Date and time the sample was collected. <br /> • Sample description. <br /> • Preservatives. <br /> • Parameters for analysis. <br /> 4.2 SAMPLE PRESERVATION AND HANDLING <br /> 4.2.1 Sample Preservation <br /> After collection, samples will be immediately stored in a cooler with ice <br /> or frozen ice pack. The appropriate preservation techniques for soil <br /> and water samples are shown in Table 1. <br /> 4-1 <br />
