Pro ect S ecific C. No project specific QC (i .e., spikes and/or <br /> uplicates 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 /> sheets in the Analytical Results section. — <br /> C. Laborator Control Samples. An LCS 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 /> order to establish method-specific control limits. The LCS <br /> results obtained for your samples were all within the following <br /> Enseco acceptability windows: <br />
