No project specific QC (i.e., spikes and/or <br /> duplicates) was requested. <br /> E. 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 <br /> Method Blank Report. <br /> Repetitions of method blanks (with identical QC Lot No.s and Run <br /> No.$) have been reported but do not indicate unique <br /> ` determinations. <br /> a' C. Laboratory Control Samples - The LCS Program <br /> Duplicate Control 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 109: of the sample load in <br /> 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 /> s <br /> :i <br /> Lr� { <br /> .3 9 <br />
