The US navy knew of potentially dangerous levels of airborne plutonium in San Francisco for almost a year before it alerted city officials after it carried out testing that detected radioactive material in November last year, public health advocates allege.
The plutonium levels exceeded the federal action threshold at the navy’s highly contaminated, 866-acre Hunters Point Naval Shipyard. It was detected in an area adjacent to a residential neighborhood filled with condos, and which includes a public park.
The city is planning to redevelop Hunters Point with up to 10,000 housing units and new waterfront commercial districts. The property was used as a staging ground for nuclear weapons testing, and the discovery marks the latest in a series of controversies and cover-ups of dangerous, radioactive material at the site.
The navy is trying to avoid spending several billion dollars to do a proper clean up, said Jeff Ruch, senior counsel with the Public Employees for Environmental Responsibility nonprofit, which is involved in litigation at the site.
“It’s been one thing after another after another,” Ruch said. “What else is in the closet? We don’t know and we’re not going to search the closet to find out.”
The navy did not respond to a request for comment from the Guardian.
