This is probably due to laboratory contamination. GCMS Scan For Unknowns Other unknown compounds ug/L 11/05/01 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-Dichlorobenzene-d4 is present at 0.32 ug/L, probably due to laboratory contamination since it is a Surrogate Standard used in GCMS methods.
