The purpose of the COC form is to establish <br />the documentation necessary to trace possession from the time of collection to disposal. <br />The COC will be filled out at least in duplicate by the field technician who has been <br />' designated to handle/ship samples to the analytical laboratory. Information contained on the COC <br />' will contain the same level of detail found on the sample labeUtags. All corrections to the COC <br />record will be initialed and dated by the person making the corrections. The custody record will <br />' include the following information: <br />- Sampler's name and organization (company) <br />' Date and time of sample collection <br />- Sample identification number, sample matrix, sample preservation, and type of <br />' sample collected (composite/grab) <br />- Analysis requested <br />' Signature of the person relinquishing samples to be transported, with the time and <br />date of the transfer noted, and signature of the designated sample custodian at the <br />' receiving facility. <br />In addition, any special analytical instructions will be noted on the COC. <br />' The relinquishing individual will record all shipping data (e.g., air bill number, transported, <br />time, and date) on the original custody form record, which will accompany the samples to the <br />' receiving facility and be retained in the facility's file. Original and duplicate custody records, <br />' together with the air bill or delivery note, constitute a complete custody record. It is the <br />environmental manager's responsibility to ensure that all records are consistent and that they are <br />' made a part of the permanent project file. <br />1 <br />' Agapito Associates, Inc. <br />
