ProPublica investigative reporter discusses cleanup at uranium sites

ProPublica investigative reporter Mark Olalde shares how, for the first time, ProPublica has cataloged cleanup efforts at more than 50 sites where uranium was processed to fuel the nation’s nuclear arsenal. Even after regulators say cleanup is complete, polluted water and sickness are often left behind. Olalde will share ProPublica’s findings in his new report titled, “The Cold War Legacy Lurking in U.S. Groundwater.”
