1 <br /> ROY F. WESTON, INC. <br /> Ei STOCKTON ANALYTICAL LABORATORY <br /> ANALYTICAL CASE NARRATIVE <br /> i <br /> Client: Soul°za Realty <br /> RFW#€ : 9109S238 <br /> Test: 602 <br /> s <br /> 1. These samples were sampled on September 26 & 27, 1991. <br /> �k <br /> 2 . A11 required holding times for these samples were met. <br /> E, <br /> 3 . The first and continuing verification calibration standards <br /> associated with these samples were mat with the exception .f <br /> m'-Xylene/Chlorobenzene on the first standard and Benzene, <br /> Toluene, p-Xylene and m-Xylene/Chlorobenzene on the end of the <br /> run standard which was high. Even with this increased <br /> sensitivity, both samples were undetected at, or below, the <br /> reporting limits. <br /> 4. The method blank associated with this group of samples was <br /> free of target analyte interferences at, or above, the <br /> f; <br /> reporting limits. <br /> i <br /> 5. Surrogate recoveries were within acceptable limits. <br /> f 6. The blank spike recovery was •within acceptable limits. <br /> 7. Matrix spikes were. not requested for this analysis. The <br /> r precision was based on the blank spike. <br /> 8 . All retention times were within QC limits. <br /> Test: TVH <br /> I. This narrative covers the analysis of one (1) water sample. <br /> E� <br /> 2. The samples was run within hold time. <br /> 3 . Continuing calibration standards were met, except for the end <br /> of run standard which was slightly high. <br /> 4 . The method blanks associated with this group of samples were <br /> free of target analyte interferences at, or above, the <br /> reporting limits with the exception of the second blank at 26 <br /> ug/l. However the sample was reported as undetected thus, k' <br /> this may have been carry over; <br /> .i <br /> l <br />
