A partial meltdown of a nuclear reactor occurred at the former Rocketdyne site in the hills between Chatsworth and Simi Valley in 1959

  • Radioactive chemicals [...] as much as 1,000 times higher than standards
  • According to federal data released on Monday
  • Of the 437 samples collected, 75 exceeded standards
  • Seven radioactive isotopes, including one known as cesium-137, measured at levels between 100 to 1,000 times higher than the standards. Other radionuclides that suggest nuclear presence include strontium-90, tritium, plutonium, and carbon-14.

Community Response

The recent data is significant to residents, activists and public officials who have fought for years for the removal of radiation and chemical contaminants [...]

The numbers provides hard evidence that not only do the radioactive materials exist, but that the levels are higher than expected.

[...] They wonder what else can be brewing within the rocks, the earth, and the groundwater within the 2,849-acre property.

Assemblywoman Julia Brownley, D-Santa Monica

  • “This confirms what we were worried about”
  • “This begins to answer critical questions about what’s still up there, where, how much, and how bad”
  • The findings are “extremely disappointing, especially because the site has already undergone two cleanup efforts by its owner, The Boeing Co., and the Department of Energy. Each declared the land fully cleaned”

Dan Hirsch, president of the activist group Committee to Bridge the Gap

  • “People have been waiting for this information for years”
  • “All those years, we were told it was clean”
  • “This data prove we’re not just a bunch of unknowledgeable people, but that everyday people are proven right”

“These are remarkable findings” -Denise Duffield, executive director for Physicians for Social Responsibility-Los Angeles

“The Santa Susana Field Laboratory is a complex of industrial research and development facilities located on a 2,668-acre portion of the Southern California Simi Hills in Simi Valley, California [...] The site is located approximately 7 miles (11 km) northwest from the community of Canoga Park and approximately 30 miles (48 km) northwest of Downtown Los Angeles. Sage Ranch Park is adjacent on part of the northern boundary and the community of Bell Canyon along the entire southern boundary.” -Wikipedia

16 miles northeast of Malibu, CA
