Title Some California Properties Have Vermiculite Insulation Containing Asbestos
Introduction LA Testing offers asbestos testing services to quickly identify its presence in vermiculite insulation and other materials.

Garden Grove, CA, April 8th, 2013

Since 2002, the California Department of Public Health (CDPH) has been conducting evaluations of the public health implications from vermiculite contamination at various facilities across the State of California.

Vermiculite is a light-weight, fire-resistant and odorless material that has been used in numerous products, including insulation for attics and walls.  Although not all materials that contain vermiculite have asbestos, many products containing vermiculite and asbestos were sold in the United States until the 1990s.  Unfortunately, many homes across California are insulated with asbestos tainted vermiculite insulation. 

According to the U.S. Environmental Protection Agency (EPA), “If you have vermiculite insulation in your home, you should assume this material may be contaminated with asbestos and be aware of steps you can take to protect yourself and your family from exposure to asbestos.”

“A mine near Libby, Montana, was the source of over 70 percent of all vermiculite sold in the United States from 1919 to 1990,” reported Michael Chapman, Laboratory Manager of LA Testing’s Garden Grove facility, a leading asbestos testing laboratory in the greater Los Angeles area.   “Vermiculite from Libby was used in the majority of vermiculite insulation in the United States and was often sold under the brand name Zonolite.  Homeowners should strongly consider testing any suspicious insulation to ensure it does not contain asbestos.  LA Testing provides sampling supplies and testing services that can quickly provide this important information to property owners and tenants.”

The EPA has classified asbestos as Group A, a known human carcinogen.  LA Testing has sponsored an online video about asbestos dangers in the home that can be seen at:
