-13- <br /> 2 . 4 .10 For transferring sample from a bailer or bladder pump <br /> outlet, hold the end of the sample tubing at or near <br /> the bottom of the sample container to minimize <br /> turbulence and consequent loss of volatiles . <br /> 2 . 4 . 11 Use the lowest bladder pump flow rate setting when <br /> collecting Total Organic Carbon (TOC) , solvents, <br /> phenolics and other volatiles to reduce loss . <br /> 2 . 4 . 12 Filter metals samples with 2V filter paper in order <br /> to eliminate any foreign matter . Flush the filter <br /> and glassware with sample water before catching a <br /> sample in a sample container . <br /> 2. 4 . 13 Collect the required samples in the appropriate con- <br /> tainers . ( see Table 2 . ) Samples to be assayed for <br /> volatiles (TOC, solvents, phenolics, etc. ) should be <br /> filled to the top of the bottle, directly from the <br /> bailer or bladder pump outlet . Samples must not be <br /> agitated during this process. Cap and seal all <br /> bottles, leaving no air bubbles inside. <br /> 2 . 4 .14 If floating hydrocarbon is present, take a sample if <br /> needed, with a bailer . Use 40-mL VOA vials . <br /> 2 . 4 . 15 Add preservatives immediately in the field, or use <br /> bottles supplied by the contract laboratory that have <br /> the appropriate preservatives added in advance. <br /> Table 2 lists the appropriate preservative to be <br /> use. When checking pH preservation, apply a few <br /> drops of the preserved sample to pH test paper with a <br /> clean eye dropper . <br /> 2 . 4 . 16 Use no preservatives if a sample begins to bubble or <br /> foam in the presence of an acid. Mark the Official <br /> Sample Label and Chain of Custody "NO PRESERVATIVE <br /> ADDED. " Notify the Environmental Testing Supervisor <br /> so provisions for rapid analysis can be made. <br /> 2 . 4 . 17 Document the observations and measurements taken at <br /> the sample site in the Field Log. <br /> Fill in the required information on the Request- <br /> for-Analysis/Chain-of-Custody form and the Sample <br /> Labels. Record the same information in the Field <br /> Log. <br />
