Collection of Samples u <br /> j <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 <br /> equipment blanks are submitted on a project specificd basis to provide for laboratory and <br /> field QA/QC. <br /> � F <br /> II <br /> l <br /> ,,Ili k <br /> I� <br /> 3 <br /> 'i <br /> r <br /> } <br /> II , <br /> 'I <br /> 4 <br /> 4203-F3 � . <br /> March 25, 1997 <br />
