Chain-of-Custody forms will be <br /> prepared for groups of samples collected at a given location on a given day. Each form will <br /> be prepared in triplicate, and one of the three copies will accompany the samples to the <br /> laboratory. one copy will be kept in the QA/QC file and another copy will be retained in the <br /> project file. The Chain-of-Custody form makes provision for documenting sample integrity <br /> Lima Ranch <br /> 13 of 17 <br /> Site Characterization Work Plan Addendum <br /> April 2008 <br />
