v <br /> r <br /> P <br /> r <br /> APPENDIX C <br /> SAMPLE HANDLING PROCEDURES <br /> soil and groundwater samples will be packaged carefully to avoid <br /> breakage or contamination, and will be delivered to the laboratory <br /> at propar storage temperatures. The following sample packaging <br /> requirements will be followed. <br /> sample bottle/sleeve lids will not be mixed. All sample <br /> lids will stay with the original containers and have <br /> custody seals affixed to them. <br /> Samples will be secure, in coolers to maintain custody, <br /> control temperature, and prevent breakage during <br /> transportation to the laboratory. <br /> A chain-of-custody form will be completed for all samples <br /> and accompany the sample cooler to the laboratory. <br /> Ice, blue ice, or dry ice (dry ice will be used for <br /> preserving soil samples collected for the Alameda County <br /> Water District) will be used to keep samples at a <br /> constant temperature during transport to the laboratory. <br /> Each sample will be identified by affixing a pressure <br /> • sensitive, gummed label, or standardized tag on the <br /> container(s) . This label will contain the site <br /> identification, sample identification number, date and <br /> time of sample collection, and the collector's initials. <br /> All groundwater sample containers will be precleaned and will be <br /> obtained from a State Department of Health Services certified <br /> analytical laboratory. <br /> Sample Control/Chain-of-Custody: All field personnel will refer to <br /> this work plan, to verify the methods to be employed during sample <br /> -..._.__ _...__.... <br /> collection.
