The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. However, bis(2-Ethylhexyl)phthalate is present at an estimated level of 0.51 ug/L. The recovery for the Surrogate Standard in this sample was 93%. Recoveries for 14 of the 44 compounds in the LCS Standard were outside of EPA 625 acceptance ranges. Soon however, GCMS method acceptance ranges will be established and used instead.
