Consumers are being warned to immediately quit using Zono-lite. EPA tests show other brands of vermiculite and some kinds of potting soil contain asbestos, said Bill Dunbar, EPA spokesman in Seattle. Anything over 1 percent is regulated as a toxic waste and requires special handling Zonolite, once manufactured in Spokane, Wash., is still being sold as a soil additive for home gar-dening, the Environmental Protection Agency said Friday. EPA is not sure how much Zonolite is on the market. EPA discovered the material in Seattle-area stores.
Some people just look for the cheapest source.
The asbestos scare in Seattle has connections to Libby, Mont., a mining town EPA has found to be seriously contaminated with asbestos.
