Asbestos testing continues at W.R. Grace Zonolite factory

The Environmental Protection Agency (EPA) continues to do asbestos testing around the site of the former W.R. Grace Zonolite factory in Spokane, Washington. Asbestos fibers were found in the yards of nearby residences during soil testing in June, and the EPA wants to know if the asbestos could become airborne during routine activities like raking or shoveling dirt.

The on-scene coordinator for the clean-up program said that the EPA is concerned that even the low levels of asbestos found in the soil could pose a risk if it becomes airborne, something they’ve learned from other sites like the one in Libby, Montana.

The W.R. Grace Zonolite factory in Spokane stopped making asbestos-laden attic insulation when the factory closed in 1973 after state inspectors were tipped off about the high levels of asbestos inside. The EPA is conducting its testing in two yards and some county-owned property. Results should be available in the next six weeks.
