'i <br /> This section describes the field and analytical procedures to be followed by Delta throughout the investigation. <br /> 5.1 General Sample Collection and Handling Procedures <br /> Proper collection and handling are essential to ensure the quality of a sample. Each sample will be collected in the <br /> appropriate container, preserved correctly for the intended analysis and stored, prior to analysis, for no longer than <br /> the maximum allowable holding time. Details on the procedures for collection and handling of soil samples from <br /> this project can be found in previous sections. <br /> 5.2 Sample Identification and Chain-of-Custody Procedures <br /> Sample identification and chain-of-custody procedures ensure sample integrity and document sample possession <br /> from the time of collection to its ultimate disposal. Each sample container submitted for analysis will have a label <br /> affixed to identify the job number, sampler, date and time of sample collection and a sample number unique to that <br /> sample. During soil sampling, this information, in addition to a description of the sample, field measurements <br /> made, sampling methodology, names of on-site personnel and any other pertinent field observations will be <br /> recorded on the borehole log or in the field records. <br />
