Mr. Bernard P. Orlan January 10, 2002 Wipe Sampling for Dioxins Page 3 P. S. 89 (Manhattan) ATC ProiectNo. 15-19125-0297
DISCUSSION
The concentrations on indoor surfaces ranged from 0.00 to 0.032 nanograms per square meter (ng/m2). No standard has been established for dioxin on indoor surfaces. The NYSDEC acceptable soil concentration is 0.0006 parts per million (ppm) or 0.6 ppb. The EPA residential clean-up goal is Ippb. The levels found in these samples would appear to be below both these levels.
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 20lh.
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.
Sincerely, ATC ASSOCIATES INC.
James R. Cohn, CIH, CSP Regional Manager Industrial Hygiene Division
