. GENESIS ENGINEERING&REDEVELOPMENT <br /> 8.3.3 Completeness <br /> Data completeness represents the percentage of measurements evaluated and judged to be <br /> valid measurements. In order to meet the completeness objective for this project, valid <br /> results will be defined as all results not qualified with an "R" flag. Data completeness is <br /> expressed as percent completeness (%C) and is defined as: <br /> %C = 100% x V <br /> n <br /> where, V= number of measurements judged valid <br /> n= total number of measurements <br /> The QA objective for completeness is 95 percent for water and 90 percent for soil analyses. <br /> 9.0 QUALITY ASSURANCE OVERSIGHT <br /> Audits are tools used to evaluate the effectiveness of the QC program with respect to the QC <br /> . requirements of the sampling and analysis activities. Two types of audits may be performed: <br /> performance audits and system audits. If deficiencies are encountered during an audit, <br /> corrective action procedures will be implemented. <br /> 9.1 Performance and System Audits <br /> Performance audits are normally conducted after the data production systems are operational <br /> and generating data. These audits consist of the collection of measurement data,by using <br /> performance evaluation samples to determine the accuracy of the total measurement system <br /> or portions thereof. <br /> 9.1.1 Laboratory Audits <br /> All laboratories participating in this Project may be audited by the QA Manager or a <br /> designated representative. Additionally, the Laboratory QC Manager will be responsible for <br /> verifying that standards,procedures, records, and charts are properly maintained and that QC <br /> records are adequately filed and maintained in a retrievable fashion. <br /> System audits are on-site qualitative inspections and reviews of the QC system, and <br /> encompass all aspects of the Project. These audits are concerned with evaluations of all <br /> components of the applicable measurement systems to determine if they have been properly <br /> • William DePaoli Property 17 of 21 <br /> Quality Assurance Project Plan <br /> February 2012 <br />
