Mr. Bernard P. Orlan July 1,2002 Wipe Samples for Dioxins Page 2 P. S. 234 (Manhattan) ATC Project No. 15-19125-0279
DIOXIN WIPE SAMPLE RESULTS (2, 3, 7, 8 TCDD EQUIVALENTS) May 21,2002
LOCATION/SAMPLE NUMBER
1st Floor Hallway - east end/DXl 0.00041
1st Floor Hallway - west end/DX2 0.000022
The New York State Department of Health (NYSDOH) established guidelines for dioxin for the re-occupancy of the Binghamton State Office Building following a PCB fire. The NYSDOH guideline for dioxin on surfaces is 25 nanograms per square meter (25 ng/m').
The concentrations on indoor surfaces were 0.000022 and 0.00041 ng/m^. These levels are well below the NYSDOH guideline.
It is not possible to determine when the 2, 3, 7, 8 - TCDD equivalents detected in these samples were deposited. Dioxin wipe samples were not collected from this school prior to December 6, 2001.
It is our pleasure to provide these indoor environmental services to the NYC Board of Education. If you have any questions about this report, please call (212) 353-8280, extension 212.
