W.R. Grace Plant, Newark, California
Overview
Introduction
The Agency for Toxic Substances and Disease Registry (ATSDR), a federal public health agency, has completed an exposure evaluation on the former W.R. Grace Plant in Newark, California. The evaluation considered ways that people could be exposed to asbestos from this site now or ways that people could have been exposed in the past.
Who should read this?
Read this alert if you or someone you know:
- Currently lives near the former W.R. Grace Newark Plant,
- Worked at the plant between 1966 and 1993,
- Lived in a household in which someone worked at the plant between 1966 and 1993, or
- Lived near the plant for any period between 1966 and 1993.
Why this site is being evaluated?
ATSDR is evaluating a number of sites throughout the United States where facilities received vermiculite from a mine in Libby, Montana. Vermiculite from Libby was found to contain asbestos. W.R. Grace Newark Plant received Libby vermiculite from 1966 to 1993.
Purpose of the alert
This alert explains:
- Who might be at risk for exposure to asbestos from the plant now or at risk from past exposure
- How people are or were exposed to asbestos
- What to do if you think you’ve been exposed to asbestos, and
- Where you can get more information.
Am I at risk for asbestos exposure?
Important!
Being exposed to asbestos does not mean that you will develop health problems! Many things need to be considered when evaluating whether you are at risk for health problems from asbestos exposure. A doctor can help you find out if you have health problems from asbestos exposure.
Former workers are most at risk
Workers may have been exposed to asbestos anywhere in and around the plant. The plant processed vermiculite that contained asbestos. Vermiculite was processed by expanding it in furnaces. Asbestos fibers were released into the air in the plant throughout the workday when vermiculite was processed and handled. Here are some examples of work activities known to have released fibers into the air:
- Unloading vermiculite from rail cars
- Moving vermiculite to furnaces
- Processing vermiculite, or
- Handling waste rock (unexpanded vermiculite) after processing.
Family members of former workers
Workers who were exposed may have brought asbestos fibers home on their clothes, shoes, and bodies. Therefore, people who lived in their households could have been exposed to asbestos, too. Even handling and washing a worker’s clothes could have exposed someone to asbestos.
Former residents
People who lived near the plant may have been exposed to asbestos in the following ways:
- Playing on waste piles. At some vermiculite plants, children living nearby played on vermiculite waste rock piles left outside the plant. They might have breathed in air containing asbestos fibers while they played there. We do not know if this occurred at the Newark plant.
- Moving or handling the waste rock. People, workers included, may have taken waste rock from the plant to their homes. This waste rock was used in many ways—for example, in gardens, in children’s play areas, and for fill or paving material. People who came into direct contact with this waste rock probably breathed in air that contained asbestos fibers.
- Breathing air within a few blocks of the site. Sometimes when the plant was operating, dust and asbestos fibers were released into the air. People who lived within a few blocks of the plant between 1966 and 1993 might have breathed in air that contained asbestos fibers.
Current residents
Most current residents living in the neighborhood are not being exposed to asbestos from the site. The plant stopped processing asbestos-contaminated vermiculite in 1993.
At some vermiculite plants, people took waste rock home from the plant and used it around their homes. We do not know if this occurred at the Newark plant. Today, people could still be exposed to asbestos around their homes if any waste rock taken home from the plant remains uncovered and open to the air. That’s because every time this waste rock is stirred up, asbestos fibers may be released into the air.
How can asbestos exposure make you sick?
Asbestos exposure and health
Asbestos is a naturally occurring mineral. It is made up of fibers that are so small that you cannot see them. If asbestos fibers are in the air you breathe, you will get asbestos fibers in your lungs. This is the primary way that people are exposed to asbestos.
Asbestos fibers may remain in the lungs for a lifetime. In some cases, the fibers might damage the lungs or the lining of the lungs, leading to illness and even death.
What should I do if I have been exposed?
Take action
Inform your doctor. Even if you don’t feel sick, tell your doctor that you might have been exposed to asbestos. Most people don’t show any signs or symptoms of asbestos-related disease for 10 to 20 years or more after exposure. Only a doctor can tell if you have any health problems due to asbestos exposure. Your doctor may refer you to a specialist who treats diseases caused by asbestos.
Show this fact sheet to your doctor. Please take this fact sheet to your doctor because the information in it might be helpful in evaluating your health risk.
Quit smoking. If you are a smoker, quit smoking. Smoking combined with asbestos exposure greatly increases the risk of getting lung cancer.
Get regular influenza (flu) and pneumonia shots. Regular inoculations help reduce the chance of lung infections.
