i / !. •1 ■ (See attached (See attached file; file' W^hiii^’M!!lette-94-App7-ultra data.pdf) The level of 393,,C^0^^oi|i^ by sonication in carpet is quite high. I have attadhec^fe that shows that even in buildings knowpi to asbestos containing materials is around 1000 stifiict<e|i^er square centimeter according to an authoritative,j^cerpts attached.

Before the WTC 1980, surface dust outdoors in New York City \^asfc||ei^ge of 5100 s/cm2 (from a study by EWir^i p&ehted at the Johnson Conference in the summer of 2002 ; ■ !

Thus, the levels definitely over background and deserve attention (l^Gdy can tell you with any certainty exactly how ^dus these levels are, but EPA statutes and poii<|^§|^y that any exposure to asbestos is hazardous, and atteilpfes to get levels to background is desirable.
