4.3.8 Data Reduction and Validation The procedures describing how to review and validate the data should be specified. They should include procedures for computing and interpreting the results from QC samples, and independent procedures to verify that the analytical results are reported correctly. In addition, routine procedures used to monitor precision and bias, including evaluations of reagent, equipment rinsate, and trip blanks, calibration standards, control samples, duplicate and matrix spike samples, and surrogate recovery, should be detailed in the procedures. More detailed validation procedures should be performed when required in the contract or QAPjP. 4.3.9 Reporting The procedures describing the process for reporting the analytical results should be specified. 4.3.10 Records Management The procedures describing the means for generating, controlling, and archiving laboratory records should be specified. The procedures should detail record generation and control , and the requirements for record retention, includ- ing type, time, security, and retrieval and disposal authorities. Proiect-specific records may include correspondence, chain-of-custody records, request for analysis, calibration data records, raw and finished analytical and QC data, data reports, and procedures used. Laboratory operations records may include laboratory notebooks, instrument performance logs and maintenance logs in bound notebooks with prenumbered pages; laboratory benchsheets; software documentation; control charts; reference material certification; personnel files; laboratory procedures; and corrective action reports. 4.3. 11 Waste Disposal The procedures describing the methods for disposal of chemicals including standard and reagent solutions, process waste, and samples should be specified. 4.4 LABORATORY QA AND QC PROCEDURES The QAPjP should describe how the following required elements of the laboratory QC program are to be implemented. 4.4.1 Method Proficiency Procedures should be in place for demonstrating proficiency with each analytical method routinely used in the laboratory. These should include procedures for demonstrating the precision and bias of the method as performed by the laboratory and procedures for determining the method detection limit ONE - 18 Revision 1 July 1992 }
