PITTSBURGH, PA - RJ Lee Group (RJLG) was retained by the National Stone, Sand, and Gravel Association (NSSGA) to review analytical data in a study conducted by the U.S. Environmental Protection Agency (EPA) during its evaluation of naturally occurring asbestos (NOA) in El Dorado Hills, California. RJLG's experts determined that the vast majority of the amphibole particles examined were not asbestos, but in fact were a massive form of the mineral. Current evidence indicates that the massive form of these minerals has not been linked to any health risks.

RJLG determined the primary issue in EPA's study was the application of incorrect mineral definitions. The scientific bases for the correct definitions have been recognized by the scientific community for the last 30 years. It is imperative that the correct definitions be used for all studies, whether for a governmental agency or for the private sector, so that the new studies can be related to historical epidemiology data.
