Bulk samples of settled dust to be analyzed for fiberglass fiber content were collected only from locations where there was sufficient amount of settled dust for bulk sampling and analysis.
ATC was able to collected bulk samples from all the aforementioned locations inside and outside the building.
The purpose 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 Friday as per the recommendation of ENVIRON and after the approval of NYC-BOE. This is the 11 consecutive week such a sampling is performed in P.S. 89M.
A total of forty (40) settled dust bulk samples were collected from the aforementioned areas where there was sufficient amount of settled dust for bulk sampling and were analyzed utilizing Polarized Light Microscopy (PLM).
Analytical results indicated that none of the forty (40) collected settled bulk samples contain fiberglass fibers.
The settled dust bulk sampling perfonned was limited to testing for fiberglass in locations indicated by ENVIRON Corp, and as outlined in the school’s BOE approved sampling protocol.
Attached please find the following:
• Settled dust bulk sample chain of custody form and laboratory results • Laboratory and personnel certificates
