Wipe Sampling for PCBs Page 2
P. S. 234 /Manhattan'! ATC Project No. 15-19125-02'’9
The two areas sampled were the Lobby Floor -East and the P* Floor hallway - West.
Each sample was analyzed for seven (7) PCB compounds (Attachment). The PCB results
of both samples were below the reporting limits (2.0 micrograms/sample) for the
analyses.
Currently, the Environmental Protection Agency spill clean-up standard for PCBs on
non-porous surfaces is 10 micrograms per 100 square centimeters or less (<10ug/I00cm’)
as stated in 40 CFR 761.
It is our pleasure to provide these indoor environmental services to the New' York City
Board of Education. If you have any questions about this report, please call (212) 353-
8280, extension 212.
Sincerely,
ATC Associates, Uc.
