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, except for the presence of bis(2-Ethylhexyl)phthalate at an estimated level of 0.46 ug/L, and 1,1,2,2-Tetrachloroethane at an estimated level of 2.7 ug/L and with a fit of 95 out of 100. These 2 compounds were also present in the Laboratory Blank at 0.33 ug/L and 2.90 ug/L respectively.
