(AP) — Federal officials say their final analysis of a Montana community wracked by a deadly asbestos contamination shows a costly and much-criticized cleanup is working, even though some 700 properties have yet to be investigated and concerns linger over asbestos left behind. Yet after a lengthy review of the health risks, the EPA said in a report issued Friday that people could continue to live in Libby and neighboring Troy without excessive exposure. "EPA's indoor and outdoor cleanups have significantly reduced risk from exposure to asbestos," agency officials said in a Friday statement.
