Results

Results ranged from less than 0.003 to 0.008 total fibers per cubic centimeter of air (f/cc). These results are below the New York State Department of Labor and New York City Department of Environmental Protection action and clearance level of 0.01 f/cc.

It is important to note that the sample analysis method used quantifies all fibers visible under the microscope and does not distinguish asbestos from non-asbestos fiber types. Therefore, actual asbestos fiber concentrations could have been lower than reported. Although not included in our contract workscope for this project, representative samples were analyzed by transmission electron microscopy and no asbestos fibers were identified.

Laboratory reports in support of this project are attached. Please contact me if you have any questions.

Sincerely, Colden Corporation

Christopher J. Wesle IH Project Manager
