Method Test Description Results Units MDL Analyzed on Validator
The recovery for bis(2-Ethylhexyl)phthalate in the MDL Standard was above its acceptance range. This is probably
due to laboratory contamination. The level of 4.5 ug/L in this sample is below the NYSDOH MCL of 6.0 ug/L.
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-Dichlorobenzene-d4 is present at 0.30 ug/L, probably due to
laboratory contamination since it is a Surrogate Standard used in GCMS methods.
