This is probably due to laboratory contamination. GCMS Scan For Unknowns Other unknown compounds ug/L 11/5/2001 DLV A scan of the extract prepared for the 508 analysis, from 35-550 amu using a mass spectrometer, does not reveal the presence of non-target compounds. However, 1,2-DichIorobenzene-d4 is present at 0.29 ug/L, probably due to laboratory contamination since it is a Surrogate Standard used in GCMS methods.
