' • As fieldwork is conducted the on-site CGRS technical lead will determine whether these <br /> procedures are being followed, if corrections need to be made, and if additional samples <br /> are required. <br /> 2.3.4 Chain of Custody Records <br /> tA Chain of Custody Record will be maintained in the field for all samples to be shipped to the <br /> laboratory for analysis.The three lines of information to be entered into the COC box titled "Project <br /> or P.O. 'are: <br /> Line 1. Client Name, i.e. "Varra Companies" <br /> Line 2. Project Name, i.e. "Varra Coal Ash Project" <br /> ' Line 3. Site Number, i.e. "2755aa" <br /> The three lines of information will be provided on the laboratory paper(hard copy) reports as a page <br /> ' header, and on the electronic deliverables as three individual fields in each analytical record. <br /> The "Sample Identification" entries to the COC will be completed as described in Section 2.3.1 of <br /> this QAPP. <br /> 2.3.5 Transfer of Custody and Shipment <br /> Due to the evidentiary nature of field sample collection, the possession of samples must be traceable <br /> from the time the samples are collected until they are introduced as evidence in legal proceedings. <br /> A sample is defined as being under a person's custody if any of the following conditions exist: (1) it <br /> is in their possession, (2) it is in their view after being in their possession, (3) it is in a secure locked <br /> location after having been in their possession, and (4) it is in a designated secure area. The <br /> following procedures will be used in transferring and shipping samples: <br /> ' • Field personnel will maintain detailed notes in field logbooks documenting the collection <br /> and identification of the required samples. The logbooks will be checked against the <br /> COC records for completeness and traceability. <br /> t • A COC record will accompany all sample shipments. When transferring samples, the <br /> individuals relinquishing and receiving will sign, date, and note time on the record. The <br /> COC documents transfer of sample custody from the field-sampling technician to another <br /> person or to the laboratory. <br /> • Each cooler is to contain samples from one site. No mixing of samples from multiple <br /> sites will be allowed in a given cooler. <br /> ' • Samples will be properly packaged for shipment and shipped to the laboratory for <br /> analysis with a separate signed COC record enclosed in each sample box or cooler. Two <br /> ' copies of this record will accompany the samples to the laboratory. The laboratory <br /> maintains one file copy, and the completed original will be returned to the project <br /> manager as part of the final analytical report. This record will be used to document <br /> sample custody transfer from the field-sampling technician to the laboratory or to the <br /> ' CGRS offices. Just prior to shipment to the laboratory, coolers will be secured with <br /> custody seals. <br /> ' • Whenever samples are split with a facility operator or government agency, a separate <br /> COC record will be prepared for those samples and so marked to indicate with whom the <br /> samples are being split. <br /> ' • The COC record showing identification of the contents will accompany all packages. <br /> The original record will accompany the shipment and the field team leader will retain a <br /> copy. <br /> ' varra Companies <br /> Quality Assurance Project Plan <br /> Page 9 <br />
