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. 8839:
Client: D.E.P. Project Name: D.E.P. Clean-up, 125 Cedar St., NY, NY Location: 1st Floor to Penthouse Samples received: 09/15/02
These results will confirm and document the data transmitted today conformance to your office. The analyses were performed in strict with the methodology of the AHERA Final Rule (CFR October 30, 1987) for clearance of abatement sites. attached The results of the sample analyses may be found on the document. volume Results reported as Struct/cc are a function of air verifiable by this collected in the field and are, as such, not only in its entirety and laboratory. This report may be reproduced not, without prior permission of this laboratory.
received full We are pleased to note that our TEM lab has is currently required for recognized accreditation from NVLAP, as samples for AHERA projects, and also approval analysis of TEM air DOH ELAP program. These analyses were under the NY State performed by ATC d/b/a ATC Associates Inc.
me regarding any questions relating to these Please contact materials.
