KLEINFELDER into the glass ampoule. The glass ampoule is then pulled out of the pipe, disengaging the syringe. The septum in the glass ampoule and drive tip reseals after the syringe is removed. To reduce the potential for introducing contaminants into the samples, the drive tip, galvanized pipe, and other equipment used for sample collection are steam cleaned and/or washed with trisodium phosphate or non-phosphate detergent solution and double rinsed with distilled water prior to use. "I"he sample probe and filters are cleaned in TSP solution and rinsed with niethyl alcohol followed by a distilled Nvater rinse prior to use. New, factory-sterilized syringe needles. 0-rings, septums and sample tubes are rised for each sample. 13-2.6 Sam ple flandlin« After labeling, the sample is Immediately scored in an iced cooler for transport to Kleinfelder's office sample control or to the analytical laboratory. A Kleinfelder chain-of-custody form accompanies the cooler. The chain-ofform includes Kleinfelder's naive, address and telephone number, the employee number of the individual who performed the sampling, the sample numbers. the date and time the samples were collected, the number of containers each sample occupies, the sample matrix (soil or ,vater) and the analyses for which the samples are being submitted, if' any. The chain-of:-custody form is signed by each person who handles the ' samples, including all Kleinl"elder employees and the receiving employee of office sample control or the analytical laboratory \,then the samples are delivered. 13-2.7 Decontamination of Ec ui merit To reduce the potential for cross-contamination.. augers and associated equipment are steam cleaned prior to drilling each boring'. In addition, sampling equipment is cleaned with a trisodium phosphate or non-phosphate detergent wash and rinsed with distilled water prior to collecting each soil sample. .13-2.8 Soil BoringClosure and Cutting Disposal Soil borings are closed immediateiv after the collection and logging of soil samples. Closure is accomplished by grouting the boring with a cement/bentonite slurry or as otherwise required. Drill cuttings will be placed in »-��allon drums NN.-rapped in plastic or spread around the boring and left on site for disposal by the site owner. If requested, Kleinfelder can coordinate disposal �i of soil and water sifter analytical results are available. 20-2864-02.E03/2019R03 2 Page 13-3 Copyright 1998, Klcinlcklu•. Inc. January 14, 1999
