Mr. Bernard P. Orlan October 2, 2002 Wipe Samples for Dioxins Page 2 P. S. 131 (Manhattan ) ATC Proiect No. 15-19125-0346
This provides a single value (in nanograms) for the analytical results for each sample. The sample locations and fi e results are shown in the table:
DIOXIN WIPE SAMPLE RESULTS (2, 3, 7, 8 TCDD EQUIVALENTS) August 23, 2002 DR NTRATION I LOCATION/SAMPLE NUMBER Main Lobby,TJX-1 0,0016 2nd Floor Hall by Room 210/DX-2 0.00059 3rd Floor Tall by Room 327/DX-3 0.000040 Blank/DX-4 ““(LOtr
The New York State Department of Health (NYSDOH) established guidelines for dioxin for the re-occupancy of the B nghamton 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 ranged form 0.00040 to 0.0016 nanograms per square meter (ng/m2) for all readings. 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. Diox n samples were not collected from these locations prior to this set of samples
It is our pleasure to provide these indoor environmental services to the DOE. If you have any questions about this report, please call (212) 353-8280, extension 212.
Sincerely, .1TC ASSOCIA TES INC.
