To accomplish this, bound and numbered field <br /> to books will be maintained b the field team to provide a daily record of significant events, <br /> g Y P Y g <br /> - observations, deviations from the work plan and measurements collected during the field <br /> activities. The BEI, Inc. on Site Supervisors will determine the necessity for any deviations from <br /> the work plan. The records will contain sufficient information so that the work activities can be <br /> reconstructed without relying on the collector's memory. All entries will be signed, dated and <br /> made with waterproof ink. Corrections to the log book will be made by drawing one line through <br /> <I the error, initialing and dating. The log book will always be stored in a secure location. <br /> 8.2) Chain-of-Custody <br /> The objective of the Chain-of-Custody Program is to allow the tracking of <br /> possession and handling of individual samples from the time of field collection through laboratory <br /> analysis. Once a sample is collected, it becomes part of the Chain-of-Custody process. A sample <br /> is "in custody" when ( 1 ) it is in someone's possession; (2) it is within visual proximity of that <br /> person; (3) it is in that persons possession, but locked up and sealed (e.g. during transport); and <br /> (4) it is in a designated secure sample storage area. <br /> 4 8.3) Chain-of-Custody Record and Request for Analysis Report <br /> Chain-of-Custody records establish the documentation necessary to trace sample <br /> possession from the time of collection to analysis. A serialized Chain-of-Custody and Request for <br /> Analysis Report will be completed and will accompany each batch of samples. The record will <br /> contain the following information. <br /> I"'' • Project name and number; <br /> • Request for Analysis control number (for cross reference); <br /> • Names of sampling team members; <br /> �J • Laboratory destination; <br /> • Carrier/waybill number; <br /> • Sample number; <br /> —� • Sample location and description; <br /> - I • Date and time collected; <br /> " 1 <br /> • Sample type; <br /> • Container type; <br /> • Special instructions; <br /> I 7 <br />
