Attn: Mr. Ben Sallemi
Re: Report of TEM Analysis
Dear Mr. Sallemi:
Following are the results of transmission electron microscopy (TEM) analysis of air samples from our Group No. 9041:
Client: D.E.P. Project Name: D.E.P. Clean-up, 125 Cedar St., NY, NY Location: Apartments 9S, 8N, 3S, 2N Samples received: 10/29/02
These results will confirm and document the data transmitted today to your office. The analyses were performed in conformance with the methodology of the AHERA Final Rule (CFR October 30, 1987) for clearance of abatement sites.
The results of the sample analyses may be found on the attached document.
Results reported as Struct/cc are a function of air volume collected in the field and are, as such, not verifiable by this laboratory. This report may be reproduced only in its entirety and not without prior permission of this laboratory.
We are pleased to note that our TEM lab has received full accreditation from NVLAP, as is currently required for recognized analysis of TEM air samples for AHERA projects, and also approval under the NY State DOH ELAP program. These analyses were performed by ATC d/b/a ATC Associates Inc.
Please contact me regarding any questions relating to these materials.
Very truly yours,
Michael A. Gorycki, Ph.D. Director of Electron Microscopy
