Sample identification and chain-of-cu <br /> stodY Pro <br /> c <br /> educes ensure <br /> sample integrity and document <br /> sample possession from the time of collection to ultimate disposal. Each sample container submitted for <br /> analysis will have a label affixed to identify the project number, sampler, date of collection, sample <br /> location, the monitoring-well number (if appropriate), and a number unique to that sample. Th <br /> q p at <br /> information will be recorded on the borehole log or n the field records, along with a description of the <br /> sample, field measurements, sampling methodology, anames of sampling personnel, and other pertinent <br /> field observations. <br /> A,standard Brown and Caldwell chain-of-custody form will be used to document possession of <br /> samples from time of collection to arrival at the laboratory. All samples will be submitted to an analytical <br /> laboratory that has been certified by the state in which the samples were collected. The sample-control <br /> officer at the laboratory will verify sample integrity and confirm that samples were collected in the proper <br /> container, preserved correctly, and that there is an adequate volume for analysis. If these conditions are <br /> met, the sample will-be assigned a unique log number by the laboratory for identification throughout <br /> analysis and reporting. The log number will be recorded on the chain-of-custody form and in the Iegally <br /> required log book maintained at the laboratory. The sample description, date received, client's name, and <br /> other relevant information will also be recorded. <br /> 1 <br /> 24 L 71R.E PORTSI W KP L l.DOC <br />
