Project Specific QC. No project specific QC (i .e. , spikes and/or <br /> duplicates) was requested. <br /> B. Method Blank Results. A method blank is a laboratory-generated <br /> sample which assesses the degree to which laboratory operations <br /> and procedures cause false-positive analytical results for your <br /> samples. <br /> No target parameters were detected in the method blanks associated <br /> with your samples at the reporting limit levels noted on the data <br /> a sheets in the Method Blank Report. <br /> C. Laboratory Control Samples - The LCSLaboratory Control Samples - The LCS Program <br /> Duplicate Control Samples.Samples. A DCS is a well -characterized matrix <br /> (blank water, sand or celite) which is spiked with certain target <br /> parameters and analyzed at approximately 10% of the sample load in <br /> F order to establish method-specific control limits. The DCS <br /> results associated with your samples are on the attached Duplicate <br /> Control Sample Report. <br /> Single Control Samples.Samples. An SCS consists of a control matrix that <br /> is spiked with surrogate compounds appropriate to the method being <br /> used. In cases where no surrogate is available, (e.g. metals or <br /> conventional analyses) a single control sample identical to the <br /> DCS serves as the control sample. An SCS is prepared for each <br /> sample lot. Accuracy is calculated identically to the DCS. The <br /> SCS results associated with your samples are on the attached <br /> a.: Single Control Sample Report. <br /> J <br /> f <br /> 1 . <br /> a <br />
