| Abstract | ATSDR evaluated the former California Zonolite/W.R. Grace & Company site in Glendale, California, because more than 120,000 tons of asbestos-contaminated vermiculite were shipped to the site and expanded by exfoliation. Commercial exfoliation of vermiculite is a process of heating uniformly graded pieces of vermiculite in a furnace to expand or pop it into lightweight nuggets. The California Zonolite/W.R. Grace & Company facility operated from 1950 to 1977. The site consists of 2.75 acres of land on the north side of greater Los Angeles. Land use around the site is commercial, light industrial, and residential. The closest residential area is located 500 yards to the east. 1990 census data indicate 1,748 people lived within 1 mile of the site during the decade after vermiculite processing ceased. While the facility was operating, workers at the facility and members of their households were exposed to asbestos from the processing and handling of asbestos-contaminated vermiculite and waste rock. Sufficient site- and process-specific information is available to consider these exposures a public health hazard. On the basis of the information available, ATSDR estimates that from 70 to 150 former workers were exposed during the time the plant operated. |
