Mr. Bernard P. Orlan June 7, 2002 Wipe Samples for Dioxins Page 2 P. S. 89 (Manhattan) ATC Project No. 15-19125-0297
This provides a single value (in nanograms) for the analytical results for each sample. Ihe sample locations and the results are shown in the table:
DIOXIN WIPE SAMPLE RESULTS (2,3, 7,8 TCDD EQUIVAl.ENTS) __________ May 2, 2002__________
1st Floor Hallway-north/DXl 1st Floor Hallway-south/DX2 0.000039 2**<* Floor Hallway-south/DX3 0.000031
May 9,2002
Floor Hallway-north/DXl 1st Floor Hallway-south/DX2 0.0014 211^ Floor Hallway-south/DX3 0.00035
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").
On 5/02/02, the concentrations on indoor surfaces ranged from 0.000031 to 0.000048 nanograms per square meter (ng/m2). On 5/09/02, the concentrations on indoor surfaces ranged from 0.000035 to 0.0014 nanograms per square meter (ng/m^). The dioxin concentrations in all of these sample are 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 samples were not collected from these locations prior to December 20, 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.
