Many methods have been devised to analyze vermiculite microscopically, but EPA has not approved a method as they did with bulk analysis for asbestos via PLM, TEM, SEM. Is there any movement toward approving a method for identifying asbestos in bulk samples of vermiculite? Homeowners and state regulators are left in a bind assuming all vermiculite is asbestos-containing. This is an area of regulatory research that appears to be missing.
