f <br /> Collection of Samples <br /> Ground-water samples are collected in the appropriately sized pre-cleaned laboratory <br /> containers. Samples for volatile organic analyses are recovered in 40 milliliter vials lined <br /> with a teflon septum. The volatile organic samples are recovered with zero headspace to <br /> prevent the loss of volatile constituents. <br /> Ground-water samples for metal analyses are filtered in the field using a pressurized bailer <br /> system. Following filtering the metal samples are acidified to pH < 2 with HNO3 or HCL <br /> and preserved in a cooled ice chest. <br /> The water sample containers are labeled with the appropriate sample number, location, <br /> project name and number, time of collection and the';date. Chain-of-custody forms are <br /> logged with the same information, signed and accompany the samples. Samples are placed <br /> in an iced cooler and transported to a state-certified analytical laboratory. Travel and field <br /> blanks are submitted on a project specific basis to provide for laboratory and field QA/QC. <br /> 1'y <br /> I <br /> i . <br /> 12 <br /> i <br /> 4203-F3 <br /> September 30, 1997 <br /> l 4 i <br />
