Wipe Sampling for PCBs Page 2
Stuyvesant High School (M477) ATCProiectNo. 15-19125-0246
The areas sampled were;
• 1 st floor Main Lobby;
• 2nd floor Bridge Entrance Lobby;
• Roof.
Each sample was analyzed for seven PCB compounds with differing percentages of chlorine.
The PCB results of alt samples were below the reporting limits (2.0 micrograms/sample). The
same results were reported for the blank.
Currently, the Environmental Protection Agency spill clean-up standard for PCBs on non-porous
surfaces is 10 micrograms per 100 square centimeters or less (<10 ug/100cm2) as stated in 40
CFR761.
It is our pleasure to provide these indoor enyiroiunental services to the New York City Board of
