Re: Limited settled dust bulk sampling for fiberglass at P.S. 234M
Dear Mr. Orlan:
At your request, ATC Associates, Inc. representative Mr. Yiannis Efstathiou visited P.S. 234M located at 292 Greenwich Street, New York, NY 10007 on January 29*, 2002. The purpose of the site visit was to perform a settled dust bulk sampling to be analyzed for fiberglass fiber content on areas indicated to ATC by ENVIRON Corp, the Parents Association environmental consultant and approved by New York City Board of Education (BOE). These areas are the following:
• L'floor hallway • Cafeteria • Gymnasium • Auditorium • Two classrooms facing South • Classroom Facing East
At the time of ATC’s site visit it was no possible to collect a settled dust bulk sample from the cafeteria and Gymnasium.
The purposed of the dust bulk sampling is to determine if settled dust in the school contains fiberglass fibers. ATC will be repeating this sampling preferably every Tuesday as per the recommendation of ENVIRON and after the approval of NYC-BOE. This is the second week such a sampling is performed in P.S. 234M.
As per your request, a total of five (5) settled dust bulk samples were collected from the aforementioned areas and were analyzed utilizing Polarized Light Microscopy (PLM).
Analytical results indicated that none of the five (5) collected settled dust bulk samples contain fiberglass fibers.
