Polynuclear aromatic hydrocarbons were analyzed by Lancaster Laboratories,Inc.using EPA Method 8270C SIM. The QC limits for PAHs and surrogate standard <br /> recoveries by LVI GUMS are advisory only until sufficient data points can be obtained to calculate statistical limits. <br /> 2. Due to the sample matrix an initial dilution was necessary to perform the analysis. Therefore,the reporting limits for the GUMS semi volatile compounds were raised. <br /> 3. The surrogate data is outside the QC limits due to unresolvable matrix problems evident in the sample chromatogram. <br /> 4. The GUMS semivolatile surrogate recoveries were outside of QC limits in this sample.Sufficient sample was unavailable to repeat the analysis. <br /> Pagel of 1 <br />
