New York Governor Andrew Cuomo has announced “alarming levels” of radiation after water contaminated with radioactive tritium leaked from the Indian Point nuclear power plant. At one monitoring well, the radiation had spiked 65,000 percent. The plant’s owner, Entergy Corporation, has said the groundwater contamination at the plant does not pose a threat to the public. Environmentalists have long called for the closure of Indian Point, citing aging infrastructure and a history of operational issues.
