Re; Limited settled dust bulk sampling for fiberglass at P.S. 150M
Dear Mr. Orlan:
At your request, ATC Associates, Inc. representative Mr. Yiannis Efstathiou visited P.S. 150M located at 334 Greenwich Street, New York, NY 10013 on February 4"', 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:
• Lobby • Multipurpose room near kitchen • Two random classrooms
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 Monday as per the recommendation of ENVIRON and after the approval of NYC-BOE. This is the third consecutive week such a sampling is performed in P.S. 150M.
As per your request, a total of four (4) 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 four (4) collected settled dust bulk samples contain fiberglass fibers.
The settled dust bulk sampling performed was limited to testing for fiberglass in locations indicated by ENVIRON and as outlined in the school’s BOE approved sampling protocol.
