t , 7.0 SAMPLE DOCUMENTATION AND CUSTODY- All pertinent field survey and sampling information will be recorded in a logbook during each day of the field effort. A logbook will be assigned to each field team and will have a unique document control number. The logbook will be bound and have consecutively numbered pages. The Field Team Leader will be responsible for ensuring that sufficient detail is recorded, and will review the site logbooks daily and initial each page reviewed. i No general rules can specify the extent of information that must be entered in a logbook, however logbooks will contain sufficient information so that one could reconstruct the field activity without relying on the memory of the field crew. All entries must be made in indelible ink. Each day's entries will be initialed and dated at the end by the author, and a line will be drawn through the remainder of the page. All corrections will consist of single line-out deletions that are initialed. Strict custody procedures will be'maintained with the field logbooks. While being used in the field, logbooks will remain with the field team at all times. Upon completion of the field effort, the logbook will be adequately secured in the office. Photocopies of the logbooks will be used as working documents. 9 Attention to the number of details is necessary to ensure proper handling of the samples once they are collected in the field. Proper labelling of the samples, maintaining and documenting sample custody, documenting sample transfer, properly packaging and shipping the samples, and notifying the proper agents that Ahe samples have been shipped are essential elements of a successful project. Sample chain of custody (COC) is a vital aspect of any analytical sampling activity. Samples and analytical results must be traceable from the time of sample collection until the time the data are utilized for any major decision. Evidence of collection, shipment, and laboratory receipt must be documented to accomplish this. The required forms include a chain-of-custody record. The COC will be filled out in the field during sample collection, will accompany the samples rr at all times, and distributed as discussed in the Sampling Plan. L .. In order to verify sample integrity; the COC serves as written conclusive proof that samples are ! taken, transferred, prepared and analyzed in an unbroken chain. By definition, samples are in custody if they are: in the possession of an authorized individual; in the field of vision of an authorized individual; or in.a secure area or a locked container. rThe field and laboratory sample custodians are responsible for sample custody during all sample handling activities. The Field Team Leader will review all documentation to ensure that all of the proper information is included before the samples are shipped. After the chain-of-custody 8054 c:\8054\kjax.gap 11
