Dear Mr. Dugan:
Enclosed please find the,analytical results of the building materials inspection conducted at 21
West Street, New York, NY.
All samples were collected and analyzed by JLC Environmental Consultants, Inc. (JLC) at the
request of Rose Associates.
According to procedure, samples were placed in double plastic bags at the site location and
transported to the JLC laboratory. Upon arrival, the samples were individually prepared and
identified as friable or non-friable and then analyzed and indexed by date of collection, receipt, and
analysis, as well as location, color, total estimated percentage of asbestos, and type(s) and
estimated percentage(s) of each asbestos fiber group and non-asbestos fiber groups.
The detailed protocol for friable bulk material sample preparation and analysis is discussed in detail
in the five sections on the following page: Introduction, Methodology, Analytical Procedures,
Polarized Light Microscopy, and Analytical Results. These sections should clarify most questions
concerning the results and documentation for this project.
JLC Environmental Consultants, Inc. appreciates the opportunity to serve your organization.
