• <br /> as to minimize environmental contamination. Waste storage and disposal <br /> facilities should comply with applicable federal , state, and local regulations. <br /> The location of long-term and short-term storage for field records, and the <br /> measures to ensure the integrity of the data should be specified. <br /> 3.2 EQUIPMENT/INSTRUMENTATION <br /> The equipment, instrumentation, and supplies at the sampling site should <br /> be specified and should be appropriate to accomplish the activities planned. The <br /> equipment and instrumentation should meet the requirements of specifications, <br /> methods, and procedures as specified in the QAPjP. <br /> 3.3 OPERATING PROCEDURES <br /> The QAPjP should describe or make reference to all field activities that <br /> may affect data quality. For routinely performed activities, standard operating <br /> procedures (SOPS) are often prepared to ensure consistency, and to save time and <br /> effort in preparing QAPjPs. Any deviation from an established procedure during <br /> a data collection activity should be documented. The procedures should be <br /> available for the indicated activities, and should include, at a minimum, the <br /> information described below. <br /> 3.3.1 Sample Management <br /> The numbering and labeling system, chain-of-custody procedures, and how the <br /> samples are to be tracked from collection to shipment or receipt by the <br /> laboratory should be specified. Sample management procedures should also specify <br /> the holding times, volumes of sample required by the laboratory, required <br /> preservatives, and shipping requirements. <br /> 3.3.2 Reagent/Standard Preparation <br /> The procedures describing how to prepare standards and reagents should be <br /> specified. Information concerning specific grades of materials used in reagent <br /> and standard preparation, appropriate glassware and containers for preparation <br /> and storage, and labeling and record keeping for stocks and dilutions should be <br /> included. <br /> 3.3.3 Decontamination <br /> The procedures describing decontamination of field equipment before and <br /> during the sample collection process should be specified. These procedures <br /> should include cleaning materials used, the order of washing and rinsing with the <br /> cleaning materials, requirements for protecting or covering cleaned equipment, <br /> and procedures for disposing of cleaning materials. <br /> ONE - 9 Revision 1 <br /> July 1992 <br />
