Subj: Re: carpet sonication results Date: 3/12/2003 5; 12:25 PM Eastern Standard Time From: Jenkins. [email protected] To: File: Wilnioth-Millette-94-App7-ultradata.pdf (4972596 bytes) DL Time (115200 bps): <12 minutes
(See attached file: Wilmoth-Mil!ette-94-App7-ultra data,pdf)
The level of 393,060 s/cm2 by sonication in carpet is quite high. I have attached a study that shows that even in buildings known to have asbestos containing materials is around 1000 structures per square centimeter, according to an authoritative book, excerpts attached.
Before the WTC collapse, in 1980, surface dust outdoors in New York City was an average of 5100 s/cm2 (from a study by Ewing presented at the Johnson Conference in the summer of 2002).
Thus, the levels you found are definitely over background and deserve attention. Nobody can tell you with any certainty exactly how hazardous these levels are, but ERA statutes and policies say that any exposure to asbestos is hazardous, and attempting to get levels to background is desirable.
