Since these compounds were <br /> below the TMDL, no further action was taken. The blank values were not <br /> subtracted from the analytical results. <br /> Due to the sample matrix an initial dilution was necessary to perform the <br /> analysis. Therefore, the reporting limits for the GC/MS semivolatile <br /> compounds were raised. <br /> Due to the nature of the sample matrix, a reduced aliquot was used for <br /> analysis. The reporting limits were raised accordingly. <br /> Due to the presence of an interferent near the retention time of <br /> acenaphthylene, the reporting limit was raised. This was due to the fact <br /> that the interferent had a significant abundance of ions at or near the <br /> mass of acenaphthylene. <br /> #=Laboratory MethodDetection Limit exceeded target detection limit <br /> N.D.=Not detected at or above the Reporting Limit. <br />
