Content:
f the media for storage is electronic (as opposed to paper or microfilm/fiche), the equipment necessary to read and present the data in an uncorrupted form should be maintained. The document retention system should allow reconstruction of all activities associated with the generation of analytical results. Retention time for records should be established consistent with licensing conditions and in accordance with the licensee’s overall QA program. Section 2.5 of ANSI/ASQC E4-1994 provides guidance on specific types of documents that should be maintained, while ASME NQA-1-994, Basic Requirement 17, details the administrative criteria that should be considered for inclusion in a program for records and their retention. Section 4.13 of ISO/IEC 17025-2005 also provides guidance on the control of records. Chapters 4 and 11 of MARLAP discuss documents that should be retained as records. 5. Quality Control in Environmental Sampling Sampling of solids, liquids, and gases involves the measurement of sample masses, flow rates, or volumes. The ACCURACY of the instruments or containers used for this purpose should be determined and checked regularly to ensure that sampling performance criteria remain within the limits specified by the MQOs. The results of mass, flow rate, or volume calibrations and associated UNCERTAINTIES should be recorded. The frequency of these calibrations should be specified and should be consistent with the DQOs of the measurement program. The collection efficiencies of the sampling equipment used should be documented; often such documentation is available from the manufacturer. HPS/ANSI N13.1-1999 provides guidance on QA and QC for air sampling instruments. Chapter 19 of MARLAP discusses measurement uncertainties in general and volume and mass measurements in particular. Sampling or measurements should be performed using equipment and methods that yield a result that is representative of the population in the particular environmental media. FIELD
