Benzo(a)pyrene is present in this sample at 0.15 ug/L. Two additional unidentified polynuclear aromatic hydrocarbons with
mass 252 may also be present at trace levels too low to confirm their identification by this method. Bis(2-
Ethylhexyl)phthalate was present in the Laboratory Blank at 0.37 ug/L. The recovery for bis(2-EthyIhexyl)phthaIate in the
MDL Standard was above its acceptance range. The recoveries for Terbacil in the LCS Standard and die Spiked Sample
were above their acceptance ranges. The Field Blank associated with this sample will be analyzed to support the
Benzo(a)pyrene finding. This sample was submitted to our laboratory using NYCDEP bottles.
