Project Specific OC. 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 /> sheets in the Analytical Results section. <br /> C. Laboratory 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 associated with your samples follow: <br /> Test: HC-IR LCS <br /> LCS ID: PHSIR1118SAB <br /> Concentration Units: ug/kg <br /> Concentration Accuracy Precision <br /> Measured X Recovery RPD <br /> Perimeter 12iLe IM ILU ILSd IM A�L Limits ICS Limit <br /> Reference Oil 200000 237000 221000 119 111 115 NC 7.0 NC <br /> NC-riot Calculated <br /> i <br />
