H & H Marina Site Background Information <br /> Page 2 of 2 <br /> SAMPLE WITHDRAWAL <br /> Water samples are collected from each monitoring well using a disposable polyethylene <br /> bailer or a dedicated plastic/Teflon tubing in conjunction with the inertia pump. Bailers are <br /> disposed after a single use (sample) and require no decontaminating; plastic tubing used <br /> with the inertia pump is either dedicated to each well point or changed at each sampling <br /> event, thereby minimizing cross contamination due to sampling devices. Samples are <br /> drawn and collected in such a manner that agitation and exposure of the ground water to <br /> the atmosphere is minimal. <br /> SAMPLING HANDLING <br /> Ground water samples are collected into laboratory-supplied 40-ml volatile organic analysis <br /> (VOA) vials with no preservative and, if appropriate, one-liter amber glass containers <br /> without a preservative; the samples are collected with no visible air bubbles present in the <br /> vials after filling and capping. Following collection, samples are appropriately labeled, <br /> placed on ice and kept in a cooler until delivered to Cal Tech Environmental Laboratories <br /> (CTEL), a State of California Department of Public Health-certified analytical laboratory,for <br /> analysis. <br /> EQUIPMENT DECONTAMINATION <br /> Any non-disposable equipment used for sample collection is thoroughly rinsed with clean <br /> water after being washed with a solution of Alconox. <br /> Advanced CeoEnvironmental,Inc. <br />
