Laboratory Quality Assurance Procedures <br /> Laboratory quality assurance procedures include those required under the DHS hazardous <br /> waste testing program. Specific laboratory quality assurance procedures are included in <br /> the laboratory quality assurance manual for surrogate recoveries, matrix spike recoveries, <br /> and matrix spike duplicate (or duplicate)results. <br /> Method Blanks. Method blanks are analyzed daily to assess the effect of the laboratory <br /> environment on the analytical results. Method blanks are performed for each parameter <br /> analyzed. Each sample to be analyzed for organic parameters contains surrogate spike <br /> compounds. The surrogate recoveries are used to determine if the analytical instruments <br /> are operating within limits. Surrogate recoveries are compared to control limits <br /> established and updated by the laboratory based on its historical operation. <br /> Matrix Spikes. Matrix spikes are analyzed at a frequency of approximately 10 percent. <br /> Matrix spike results are evaluated to determine whether the sample matrix is interfering <br /> with the laboratory analysis and to provide a measure of the accuracy of the analytical <br /> data. Matrix spike recoveries are compared to control limits established and updated by <br /> the laboratory based on its historical operation. <br /> Laboratory Duplicates. Laboratory duplicates are analyzed at a frequency of <br /> approximately 10 percent. Spike duplicate results are evaluated to determine the <br /> reproducibility (precision) of the analytical method. Reproducibility values are compared <br /> to control limits established and updated by the laboratory based on its historical <br /> operation. <br /> Laboratory quality control data are included with the analytical results. This quality <br /> control data will include method blanks, surrogate spike recoveries (for organic <br /> parameters only), matrix spike recoveries, and matrix spike duplicates. <br /> Foothill WQPS Rev Ldoc <br /> A-8 <br />
