»WgE r DATA MDUCTION, VALIDATION, AND REPORTING Data travels through several processes before the final data package is released to the client. The path from the instrument response to the final report begins with the documentation of all testing parameters in the analyst's notebook. All calculations for the sample as well as the quality control measurements are also documented in the notebook. once the analyst is satisfied that the analytical batch meets all quality control requirements and has quantitated the sample, the result is transferred to a set of laboratory worksheets specific to the client's requests on the chain of custody. When completed the worksheets are submitted to the project manager for review. The project manager reviews the results, and checks that the analyses performed are appropriate to the client's requests. Related analyses from the same sample are compared for coherence, and the data is compared with previous results from the same source to observe any deviations from established trends. Unusually high results, or those clearly in violation of discharge limits or hazardous waste standards, are reviewed carefully for any reporting unit errors and frequently trigger an examination of the analyst's notebook and instrument printouts to check for calculation errors. Final review often involves further consultation with clients. After typing, the report is again reviewed by the project manager to ensure accurate transfer of - information from the laboratory worksheets to the final report. The laboratory director is responsible for the final review of the report, to which he adds his signature. Copies of -- final reports are kept in a secure filing area for a minimum of ten years and include the original laboratory worksheets and the chain of custody.
