Causes 48106-3 Ref: 1108 Bell Laboratories 600 Mountain Avenue Murray Hill, New Jersey 07974 Phone (201)582-3000 January 9, 1980 Mr. Walter Tripp New Jersey Bell Telephone Company 540 Broad Street Room 502 Newark, New Jersey 07101 Dear Walt: The bulk sample you sent from 210 Malapardis Road, Whippany, New Jersey, has been analyzed for asbestos. An x-ray diffraction scan revealed a significant crystalline por tion of the material to be amosite, an asbestiform mineral belonging to the amphibole group. An optical examination of the material by polarized light microscopy and disper sion staining revealed the presence of many asbestiform birefringent fibers. The dispersion staining characteris tics of these fibers were similar to those of amosite. Sincerely, MH-8685-VRC-sma Copy to R. L. Beach - AT&T Vicki R. Cohen R. W. Stone, M.D G. P.
