Here in New York, environmental groups and community members are sounding the alarm after Holtec International, the owner of the decommissioned Indian Point nuclear facility, said it plans to dump some 1 million gallons of radioactive water into the Hudson River as soon as August. The water contains tritium, a byproduct of nuclear fission that cannot be filtered out of water and which could lead to a host of negative environmental and health effects. The advocacy group Riverkeeper said, “It’s time to draw the line against using the Hudson as a dumping ground.”
