Quality Assurance Project Plan for Removal Action <br /> APN 209-450-03,Mountain House,CA <br /> Page 13 <br /> This level of validation consists of a detailed review of sample data, including verification of data <br /> calculations for calibration and quality control samples to assess if these data are consistent with method <br /> requirements. Upon request, the laboratory will make available all supporting documentation in a timely <br /> fashion. <br /> 9.4 SCHEDULING <br /> If audits are conducted, they will be scheduled such that field and laboratory activities are adequately <br /> monitored, or in the event discrepancies are identified. The overall frequency of audits conducted for <br /> these activities will be based on the importance and duration of work, as well as significant changes in <br /> project scope or personnel. <br /> 9.5 REPORTS TO MANAGEMENT AND RESPONSIBILITIES <br /> Upon completion of any audit, the auditor will submit to the Project and Field Manager a report or <br /> memorandum describing any problems or deficiencies identified during the audit. It is the responsibility <br /> of the Project Manager to determine if the deviations will result in any adverse effect on the project <br /> conclusions. If it is determined that corrective action is necessary,procedures outlined in Section 9.6 will <br /> be followed. <br /> 9.6 CORRECTIVE ACTION <br /> Corrective actions will be initiated whenever data quality indicators suggest that DQOs have not been <br /> met. Corrective actions will begin with identifying the source of the problem. Potential problem sources <br /> include failure to adhere to method procedures, improper data reduction, equipment malfunctions, or <br /> systemic contamination. The first level of responsibility for identifying the problems and initiating <br /> corrective action lies with the analyst/field personnel. The second level of responsibility lies with any <br /> person reviewing the data. Corrective actions may include more intensive staff training, equipment repair <br /> followed by a more intensive preventive maintenance program, or removal of the source of systemic <br /> contamination. Once resolved, the corrective action procedure will be fully documented, and if DQOs <br /> were not met, the samples in question must be recollected and/or reanalyzed utilizing a properly <br /> functioning system. <br /> 10.0 REFERENCES <br /> United States Environmental Protection Agency (USEPA).
