Laboratory Quality Control Procedures <br /> ' Laboratory quality control procedures will include those required under the OEHHA <br /> Hazardous Waste Testing Program Specific laboratory quality assurance <br /> procedures are included in the laboratory's QAIQC manual, including reporting <br /> surrogate recoveries, matrix spike recoveries, and matrix spike duplicates (or <br /> duplicate) results <br /> ' Method blanks will be analyzed daily to assess the effect of the laboratory <br /> environment on the analytical results Method blanks will be performed for each <br /> ' parameter analyzed <br /> Each sample to be analyzed for organic parameters will contain surrogate spike <br /> ' compounds The surrogate recoveries will be used to determine if the analytical <br /> instruments are operating within limits Surrogate recoveries will be compared to <br /> control limits established and updated by the laboratory based on its historical <br /> ' operation <br /> Matrix spikes will be analyzed at a frequency of approximately 10 percent Matrix <br /> spike results will be evaluated to determine whether the sample matrix is <br /> interfering with the laboratory analysis and to provide a measure of the accuracy of <br /> the analytical data Matrix spike recoveries will be compared to control limits <br /> ' established and updated by the laboratory based on its historical operation <br /> Laboratory duplicates will be analyzed at a frequency of approximately 10 percent <br /> ' Spike duplicate results will be evaluated to determine the reproducibility <br /> (precision) of the analytical method Reproducibility values will be compared to <br /> control limits established and updated by the laboratory based on its historical <br /> operation <br /> Laboratory QA/QC data will be included with the analytical results This QA/QC <br /> ' data will include method blanks, surrogate spike recoveries (for organic <br /> parameters only), matrix spike recoveries, and matrix spike duplicates <br /> 1 <br /> ' C-14 <br /> 1 <br />
