The sample locations and the results are shown in the table:
DIOXIN WIPE SAMPLE RESULTS (2, 3, 7, 8 TCDD EQUIVALENTS) August 20, 2002
'jv:a
1^1 Floor Haliway-north/DXl 0,000059 1st Floor Hallway-south/DX2 0.00096 Floor Hallway-south/DX3 0.00032
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 ranged from 0.000059 to 0.00096 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. 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 DOE. If you have any questions about this report, please call (212) 353-8280, extension 212, '
