MEMORANDUM
DATE: June 17, 2002
SUBJECT: LABS OFFERING EPA’s ULTRASONICATION TEST FOR CARPETS AND OTHER FABRICS
ADDENDUM TO 6Z9/02 MEMORANDUM
FROM: Cate Jenkins, Ph.D.* [email protected] Waste Identification Branch (Mail Code 5304 W) Hazardous Waste Identification Division
TO: Affected Parties and Responsible Officials
This memorandum lists laboratories currently known’ to offer EPA’s ultrasonication test for dust in carpets and woven fabrics.This state-of-the-art test gives results as the number of asbestos structures per square centimeter (s/cn?). The results can then be related to background levels and safety guidelines.
A major advantage in this test is that you do not need a consultant or industrial, hygienist to take samples. The laboratory cost for an ultrasonication test is not substantially more than for a microvacuum test (around $150), which requires a consultant to take the sample.
This memorandum is an addendum to my 6/9/02 memorandum titles “Carpets, the Asbestos Reservoir” which discusses the method in much gi eater detail. The 6/9/02 memorandum is posted at the New York Environmental Law and Justice web site at www.NYenviroLAW.org .
* The conclusions and opinions in this memorandum are those of the author and do not necessarily reflect those of the U.S. Environmental Protection Agency.
