Re: Report of TEM Analysis
Dear Mr. Burkhardt:
Following are the results of transmission electron microscopy (TEM)
analysis of air samples from our Group No. 8838:
Client: D.E.P.
Project Name: D.E.P. Clean-up, 125 Cedar St., NY, NY
Location: Entire Building
Samples received: 09/15/02
These results will confirm and document the data transmitted today
to your office. The analyses were performed in strict 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 Str-.tct/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 A'T. Associates Inc.
Please contact me regarding any questions relating to these
materials.
Very truly yours,
