Woodward-Clyde <br /> Lanalytical accuracy within the sample matrix could not be assessed for the TPH analyses <br /> using surrogate data, since a surrogate compound was not added prior to extraction or <br /> analysis. The overall analytical accuracy for the TPH analyses was assessed using laboratory <br /> control sample data, which met the laboratory evaluation criteria. A laboratory control <br /> sample was analyzed for BTEX (water matrix) and the recoveries were within the laboratory <br /> control limits. The reported surrogate recoveries were within the laboratory-established <br /> control limits. Based on the above data review, no qualification of sample data was <br /> required. The data are considered acceptable for their intended use. <br /> I <br /> L <br /> I' <br /> �i <br /> I <br /> I� <br /> rr <br /> L' <br /> I <br /> L <br /> 8054/FEMA anxPIEx.M/9-z4-v5snc 3-3 <br />
