Asbestos & WR Grace Plant: Conclusions about Workers:

• Currently, the site remains unoccupied and access is restricted. Therefore, no worker exposures are occurring at this time.
• People who worked at the Zonolite Company/W.R. Grace exfoliation facility were probably exposed to levels of asbestos exceeding the current workplace standard.
• People who lived with former workers were probably also exposed to elevated asbestos levels from fibers carried home on workers’ hair, skin, and clothing.
• People who worked at landfills that received Zonolite Company/W.R. Grace exfoliation waste may have been exposed to asbestos. Data on the extent of these exposures are not available.
• If workers at the former mulch company were exposed, these exposures were probably minor and are not expected to cause any adverse health effects.
• Future disturbances of soil or renovations at the site could cause further asbestos exposures.
