Waste Rock Contaminated With Asbestos Can be Lethal

Asbestos-contaminated waste rock was not observed by ATSDR staff members when they visited the site. Based on the results of the National Institute of Safety and Health on-site air samplings, current workers are not being exposed to asbestos, either from the products they are processing or through other indoor air exposures. ATSDR is evaluating the former Zonolite and W.R. Grace plant in cooperation with the Florida Department of Health.
