A scan of the extract prepared for the 508 analysis, from 35 to 550 amu using a mass spectrometer, reveals the presence of the following compounds at estimated levels: Benzo(a)anthracene - 0.30 ug/L, fit - 97 Bis(2-ethylhexyl)phthalate - 0.56 ug/L, fit - 99 Chrysene - 0.34 ug/L, fit - 94 Benzo(k)fluoranthene - 0.30 ug/L, fit - 95 This sample will be re-extracted and re-analyzed, along with its Field Blank. Re-analysis of this sample on 12/20/01 shows that it is clean. The Field Blank is clean also.
