A federal report that found a secret Hicksville plant had been contaminated with nuclear waste was made public recently, two years after its completion.

The Army Corps of Engineers determined in 2005 that the former Sylvania Nuclear Products facility site could pose a risk to public health. Sylvania secretly processed uranium at the plant, located at Cantiague Rock Road and West John Street, in the 1950s and 1960s. Residents weren't informed of Sylvania's nuclear activities until 2001. News 12 Long Island obtained a copy of the report through the Freedom of Information Act.

According to the report, "there is evidence of a release and/or threat of release into the environment of hazardous substances, specifically radioactive materials."

The Army Corps of Engineers also states in the report that uranium byproducts were incinerated on site, and 235,000 PCIs of uranium were later found in a single tank. Twenty PCIs of uranium is the normal level in soil.

Adrienne Esposito, with the Citizens Campaign for the Environment, is livid.

"Instead of being honest with the public, they covered it up," Esposito said. "That is negligence on the part of the federal government and that's a conspiracy to keep the public in the dark."

George Johnson, a neighbor of the site for seven years, said nobody ever told him about the former nuclear products facility.

"How many people have to die before something happens, before we do the right thing?" he said.
