C) <br /> 7 <br /> � . bailed dry and then allowed to recover to approximately 80 <br /> percent of its static water level before being pumped dry again, <br /> or after approximately two hours . Rapidly-recovering wells will <br /> F. be pumped or bailed near-continuously until all stagnant water <br /> has been removed. <br /> F. One groundwater sample will be collected manually (hand-bailed) <br /> using a Teflon bailer. The sample will be transferred into 40-ml <br /> VOA vials with Teflon septa and 1-liter amber-colored glass <br /> Fbottles . The sample will be stored in a chilled cooler <br /> containing crushed ice to maintain the sample at 4°C for delivery <br /> to the laboratory. A field blank sample and duplicate will also <br /> be collected for quality control purposes . Strict <br /> F chain-of-custody protocols will be followed in all phases of <br /> sample handling. <br /> Depth-to-groundwater will be measured using an electric water <br /> level meter when possible . Floating petroleum hydrocarbons <br /> (product) on the groundwater, if present, will be measured with <br /> an electronic product/water interface probe. Additionally, the <br /> F product will be observed and measured using a clear acrylic <br /> product bailer. <br /> r Purged water during sampling activities will be contained in a <br /> covered and sealed drum pending resul s of the groundwater <br /> sample . The purged water will be disposed offsite . <br /> L , All equipment used during this investigation which might come <br /> into contact with contaminated materials will be thoroughly <br /> cleaned before and after each use . T is will be accomplished by <br /> washing with Alconox (a laboratory-grade detergent) and/or <br /> cleaning with high-pressure hot water (steam cleaning) . <br /> After being sealed and labeled, group water samples will be <br /> maintained at a temperature of 4°C by using crushed ice during <br /> delivery to the laboratory and prior to analysis by the <br /> laboratory. Samples will be analyzed at the laboratory within <br /> specific holding times . <br /> Documentation <br /> o The following information will be entered on the sample <br /> collection data form at the time of sampling: <br /> F - project name and number <br /> sampler' s name <br /> - time and date of sampling <br /> - sampling location <br /> sampling method <br /> A-2 <br /> F <br />
