The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. However, di-n-butylphthalate is present at an estimated level of 0.28 ug/L. The recovery for the Surrogate Standard in this sample was 68%. Recoveries for 41 of the 44 compounds in the LSC Standard were outside of EPA 625 acceptance ranges, soon however, GCMS method acceptance ranges will be established and used instead.
