Prosect 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 and <br /> procedures cause false-positive analytical results for your sample <br /> C Laboratory Control Spike A Laboratory Control Spike (LCS) is a <br /> sample which is spiked with 30 ppb BTEX, and analyzed at approximately <br /> 10% of the sample load in order to establish method-specific control <br /> limits The LCS results associated with your samples are on the attached <br /> 8020 Modified LCS BTEX Analysis Report <br /> • D. Matrix Spike Results A Matrix Spike is a sample which is spiked with <br /> 30 ppb BTEX, and analyzed at approximately 10% of the sample load in <br /> order to establish method-specific control limas The Matrix Spike results <br /> associated with your samples are on the attached 8020 Modified Matrix- <br /> Spike BTEX Analysis Report <br /> No target parameters were detected in the method blank associated with <br /> your sample at the reporting limit levels noted on the data sheets in the <br /> Analytical Results section <br /> Accuracy is measured by Percent Recovery as in <br /> % recovery = measured concentration x 100 <br /> (actual concentration) <br /> IV Analysis Results <br /> Results are on the attached data sheets <br /> 3050 Fite Circle Suite 112 • Sacramento California 95827 • (946) 362-8947 • FAX(916) 362-0947 <br />
