MSs/MSDs or Laboratory Fortified Blanks (to assess accuracy of the methods and <br /> precision of the method relative to the specific sample matrix) <br /> Internal Standards (to assess method accuracy and sensitivity) <br /> Compound Quantitation Limits and MDLs (to assess sensitivity as compared to <br /> project-specific requirements) <br /> Co-located samples RPDs (to assess precision of the method relative to field <br /> sampling techniques, the specific sample matrix, and representativeness of the <br /> sample aliquot to the area sampled) <br /> The results of the data validation and any corrective actions implemented are recorded <br /> on a QA/QC worksheet. The data reviewer will initial and date the QA/QC worksheet. <br /> The Site Project Manager will provide secondary review of the QA/QC worksheet and <br /> will also initial and date the QA/QC worksheet. The initialed and dated QA/QC worksheet <br /> will be attached to the final analytical laboratory report that is retained in the project files. <br /> In addition, a summary of the data validation, including a list of all qualified data, will be <br /> provided in the Site Investigation report. <br /> A3.0 REFERENCES <br /> U.S. EPA. 1991.
