The breakdown for Endrin in the Breakdown Standard is 53%. Recoveries for 6 of the 18 compounds in the MDL
Standard were outside of their acceptnace ranges. Recoveries for 4 of the 18 compounds in the LCS Standard were
outside of their acceptance ranges. The level for bis(2-Ethylhexyl)phthalate was 0.73 ug/L in the Laboratory Blank.
GCMS Scan For Unknowns
Other unknown compounds ug/L 12/5/2001 DLV
A scan of the extract prepared for the 508 analysis, from 35-550 amu using a mass spectrometer, does reveal the
possible presence of 4-ethoxy-benzoic acid ethyl ester at an estimated level of 1.1 ug/L and
bis(2-Ethylhexyl)decanedioic acid at an estimated level of 42 ug/L. Also present in the chromatogram are
compounds from column bleed. The Field Blank for this sample will be analyzed.
