R9 Laboratory SOP 845
INTERNAL DATA REVIEW & REPORT PREPARATION
Summary
This SOP is applicable to evaluation and reporting of analytical data generated by the USEPA Region 9 Laboratory. It involves the independent reviews of data packages which normally consist of case narratives, raw data, QC summaries, results spreadsheets, log book entries, and chain of custody. The reviews are performed prior to preparation and issuance of a final report to the client. This SOP is applicable to both ESAT and EPA generated data and for all programs, however, the contents of data packages may vary. All reviews must be performed by qualified personnel only. For ESAT generated data, the final laboratory review is always performed by the EPA WAM or designee or the LQAO. These final laboratory EPA reviews of ESAT generated data are for completeness and accuracy and are performed as a contract oversight function for both analytical and quality assurance work assignments. The final review of ESAT data is not an extensive technical review. The in depth technical review is performed prior to the final review, but any errors noted are corrected prior to issuance of a report to the client. Further review, evaluation and reporting may be performed by the Regional Quality Assurance Office at the request of the client.
Analytical and quality control requirements are covered in the respective analytical SOPs for the various types of analysis. These SOPs are consulted whenever reviews are performed to ensure that all quality control parameters are met and that data is properly flagged to reflect any failed quality control requirements. ESAT generated data undergoes internal review prior to submission to the EPA WAM in accordance with ESAT internal review procedures. All EPA generated data is peer reviewed prior to review by the EPA Laboratory Quality Assurance Officer or designee prior to submission of the final laboratory report to the client. There are many varied types of analysis and this SOP attempts to establish a general review procedure that is applicable to all analyses. All steps in this procedure may not be applicable to all analysis types. Documentation of reviews, using review forms and/or check lists, is to be included with the complete data package file. If systemic or repeated problems are noted during the review process, analysts and/or reviewers are expected to make an entry to the corrective action data base so the problem can be documented, investigated, and resolved. All final laboratory reports to clients are submitted under the signature of the Laboratory Director.
