KLE/NFELOER <br /> mpmxoq.aquxwxw <br /> from the boring. The desired 6-inch interval is cut out, covered with Teflon and sealed with tight <br /> fitting plastic caps. <br /> Each sample is individually labeled. The label includes Kleinfelder's name, job number, the <br /> date and time the sample was collected, the employee number of the individual who performed <br /> the sampling, and a unique sample identification number. <br /> B-2.6 Sample Handling <br /> After labeling, the sample is immediately stored in an iced cooler for transport to Kleinfelder's <br /> office sample control or to the analytical laboratory. A Kleinfelder chain-of-custody form <br /> accompanies the cooler. The chain-of-custody form includes Kleinfelder's name, address and <br /> telephone number, the employee number of the individual who performed the sampling, the <br /> sample numbers, the date and time the samples were collected, the number of containers each <br /> sample occupies, the sample matrix (soil or water) and the analyses for which the samples are <br /> being submitted, if any. The chain-of-custody form is signed by each person who handles the <br /> samples, including all Kleinfelder employees and the receiving employee of office sample <br /> control or the analytical laboratory when the samples are delivered <br /> B-2.6 Decontamination of Equipment <br /> To reduce the potential for cross-contamination, Geoprobe pipe and associated equipment are <br /> steam cleaned prior to advancing each boring. In addition, sampling equipment is cleaned with <br /> a non-phosphate detergent wash and rinsed with distilled water prior to collecting each soil <br /> sample. <br /> B-2.7 Geoprobe Closure <br /> Upon completion of Geoprobe sampling, the borings will be closed by backfilling the borings <br /> with a neat cement grout, bentonite chips or powder and/or per county guidelines. <br /> B-2.8 Soil Boring Closure and Cutting Disposal <br /> Soil borings are closed immediately after the collection and logging of soil samples. Closure is <br /> accomplished by grouting the boring with a cement/bentonite slurry or as otherwise required. <br /> Drill cuttings will be placed in 55-gallon drums, wrapped in plastic or spread around the boring <br /> and left on site for disposal by the site owner. If requested, Kleinfelder can coordinate disposal <br /> of soil and water after analytical results are available. <br /> 133385.4//STO13R0698 B-2 January 7,2014 <br /> Copyright 2014 Kleinfelder <br />
