Communities Against a Radioactive Environment

Tri-Valley CAREs stops nuclear weapons where they start.

We watchdog the nuclear weapons complex and its Livermore Lab, one of two locations that develops all US nuclear bombs and warheads. Nuclear weapons pose one of the great social, economic, and ecological challenges of our time. We work toward their global abolition.

Our story

Tri-Valley CAREs was founded in 1983 in Livermore, California by concerned neighbors living around the Lawrence Livermore National Laboratory, one of two locations where all US nuclear weapons are designed. Tri-Valley CAREs monitors nuclear weapons and environmental clean-up activities throughout the US nuclear weapons complex, with a special focus on Livermore Lab and the surrounding communities.

Tri-Valley CAREs’ overarching mission is to promote peace, justice and a healthy environment by pursuing the following five interrelated goals:

  1. Convert Livermore Lab from nuclear weapons development and testing to socially beneficial, environmentally sound research.
  2. End all nuclear weapons development and testing in the United States.
  3. Abolish nuclear weapons worldwide, and achieve an equitable, successful non-proliferation regime.
  4. Promote forthright communication and democratic decision-making in public policy on nuclear weapons and related environmental issues, locally, nationally and globally.
  5. Clean up the radioactive and toxic pollution emanating from the Livermore Lab and reduce the Lab’s environmental and health hazards.

After a nearly 2-year delay, the Department of Energy’s National Nuclear Security Administration (NNSA) announced that it will release a new Site-Wide Environmental Impact Statement (SWEIS) in October. The plans that will be disclosed in the SWEIS will affect the operation of Lawrence Livermore National Laboratory for the next 15 years.

In 2020, Lawrence Livermore National Laboratory (LLNL) announced it would be releasing a Site-Wide Environmental Impact Statement (SWEIS). This document will “analyze the potential environmental impacts for continuing operations of LLNL for approximately the next 15 years.”

A “scoping” period for the SWEIS occurred in 2021, which included a public hearing and written public comment period. Livermore-based community group Tri-Valley CAREs activated hundreds of community members to submit written and oral comments.


Your views: Join Town Hall to discuss Livermore Lab’s Site 300 explosives testing range

September 10, 2022

Site 300 is a high explosive testing range at the edge of Tracy. Livermore Lab conducts explosions, some inside a building and some in the open-air. 

The Environmental Protection Agency has placed Site 300 on its Superfund list of the most contaminated sites in America. 

The site’s open-air tests have released large volumes of hazardous material. These activities threaten our community. Our families in San Joaquin County are downwind. Livermore Lab’s parent agency, the National Nuclear Security Administration, will release to the public a new Site-Wide Environmental Impact Statement (SWEIS) in October.
