disposable 0 45-micron acrylic copolymer filter will be threaded onto the transfer <br /> vessel at the discharge point, and the vessel will be sealed Pressure will be <br /> applied to the vessel with a hand pump and the filtrate will be directed into the <br /> appropriate containers Each filter will be used once and discarded <br /> When a bladder pump is used to collect samples for dissolved constituents, <br /> filtering will be performed by attaching a disposable 0 45-micron acrylic copolymer <br /> filter directly to the pump effluent line with a pressure fitting As the pump cycles, <br /> the effluent will be pressured through the filter and directed into the appropriate <br /> containers Each filer will be used once and discarded <br /> Sample Collection - Soil <br /> Sample collection procedures include equipment cleaning, location description, <br /> discrete and composite sample collection <br /> Equipment Cleaning <br /> Sample bottles, caps, and septa used in sampling for volatile and semi-volatile <br /> organics will be triple rinsed with high-purity deionized water After being rinsed, <br /> sample bottles will be dried overnight at a temperature of 200°C Sample caps <br /> N and septa will be deed overnight at a temperature of 60°C Sample bottles, caps, <br /> and septa will be protected from solvent contact between drying and actual use at <br /> the sampling site Sampling containers will be used only once and discarded after <br /> analysis is complete <br /> Plastic bottles and caps used in sampling for metals will be soaked overnight in a 1 <br /> ' percent nitric acid solution Next, the bottles and caps will be triple rinsed with <br /> deionized water Finally, the bottles and caps will be air dried before being used at <br /> the site Plastic bottles and caps will be constructed of linear polyethylene or <br /> ' polypropylene Sampling containers will be used only once and discarded after <br /> analysis is complete <br /> ' Stainless steel or brass cylinders will be cleansed with detergent and hot water <br /> to dry and rinsed with methanol or isopropyl alcohol <br /> iSoil samples for hydrocarbons shall be collected in accordance with the LUFT <br /> Field Manual as follows <br /> 1 c-5 <br />
