This is probably due to laboratory contamination. GCMS Scan For Unknowns Other unknown compounds ug/L 11/6/2001 DLV A scan of the extract prepared for the 508 analysis, from 35 - 550 amu using a mass spectrometer reveals the presence of the following compounds with estimated levels: bis(2-Ethylhexyl)phthalate - 0.27 ug/L Benzo(b)fluoranthene - 0.31 ug/L Benzo(k)fluoranthene - 0.45 ug/L lndeno(1,2,3-cd)pyrene - 0.46 ug/L Dibenz(a,h)anthracene - 0.54 Benzo(g,h,i)perylene - 0.44 ug/L Stat charge for VOLATILE organic Completed 10/3/2001 12:04 AM SV
