The field staff, <br /> environmental professionals or technicians, are responsible for proper sample handling and <br /> documentation of the sample collection. <br /> 4 Equipment and Supplies <br /> The field staff will use a pen with blue or black waterproof ink to record field activities and document <br /> sample handling on field data sheets. A laptop computer with laboratory-provided software may also <br /> be used for sample documentation. <br /> 5 Procedure <br /> Proper field sampling and documentation help ensure sample authenticity and data integrity. These <br /> procedures describe sample collection documentation and sample handling, tracking, and custody <br /> procedures to ensure that sample integrity and custody are maintained. <br /> If the computer is being used to scan the samples as they are collected the data recorded by the <br /> computer should be checked for correctness. The date and time on the computer should be checked <br /> prior to scanning of any samples. The sample label should be completed when the sample is <br /> collected. <br /> 5-1 <br />
