Douglas P. Guarino is a senior reporter with Global Security Newswire, covering nuclear, chemical and biological security and proliferation issues. He has won a half dozen journalism awards over the past decade, including two national Sigma Delta Chi awards for public service from the Society of Professional Journalists. His first Sigma Delta Chi recognized a 2008 series of articles that uncovered the U.S. Environmental Protection Agency's plans to relax radiation protection standards for drinking water during terrorist attacks and other emergencies. The second was for a 2011 series that detailed gaps in EPA's radiation monitoring efforts during the Fukushima disaster, and showed how agency statements meant to assure the American public of its safety conflicted with its own health standards. A series from 2010 earned Guarino the Robert D.G. Lewis Watchdog Award, the Washington, D.C. chapter of SPJ's highest honor. These articles revealed not only a complete lack of a federal plan for cleaning up after nuclear power plant accidents, but also that EPA had for three decades hidden its fears that thousands of people living on former phosphate mines in central Florida were being exposed to dangerous levels of radiation.
