Sample No. AD23081 Method Test Description Results Units MDL Analyzed on Validator Recoveries for three of the eighteen compounds in the MDL Standard were above their acceptance ranges. The recovery for Terbacil in the LCS Standard was above its acceptance range. The recoveries for six of the eighteen compounds in the Spiked Sample were outside their acceptance ranges. The recovery for one of the three Surrogate Standards in this sample was below its acceptance range. GCMS Scan For Unknowns Other unknown compounds ug/L 10/10/01 DLV A scan of the extract prepared for the 508 analysis, from 35 - 550 amu using a mass spectrometer, does reveal the gasence of non-target compounds. These hydrocarbons do not appear to be present in the Laboratory Blank. Vwever, these hydrocarbons were present in previous Laboratory Blanks, and also some samples, analyzed for this NYCDEP project. An investigation is being made to determine the source of these hydrocarbons, if other than the samples themselves, i.e. laboratory equipment and reagents.
