Determine <br />' whether corrective action is required and, if action is required, inform the <br />appropriate personnel. <br />• Verify that the samples were analyzed within the method)-specified holding <br />,' time. If holding times were not met, this must be documented and included <br />in the job file. <br />'' • Prepare case narratives which will be included in the final) analytical report, <br />when necessary (severe matrix interference problems resulting in high <br />' detection limits, missed hold times, quality control problims, etc.-. <br />If the requirements listed above (ormethod-specified requir@ments) were not <br />' met, reanalysis of the sample may be necessary. <br />14.4 Quality Assurance Review And Data Audits <br />The QA/QC coordinator is responsible for reviewing and app~oving the quality <br />assurance report prior to delivery of the final analytical re ort to the client. <br />' Complete analytical and quality assurance data audits shoul~ be performed on <br />approximately five percent of the completed jobs.

If holding times were not met, document this non-colhformance in the <br />.job file. <br />• Verify that quality control sample checks were analyzed at the proper <br />frequency and that quality control sample performance criteria were met. <br />' • Review the final analytical and quality assurance reports to assure that the <br />data reported is correct (significant figures, method references, detection <br />~ limits, units, and date and time analyzed. <br />~~ <br />
