Tri-Valley CAREs will have a Virtual Community Meeting on Tuesday December, 8th 2020 at 7:30 PM, on Site 300 in Tracy. We will bring attention to and discuss the slow-going Superfund cleanup and the proposed increase in bomb blasting planned for Livermore Lab's nearby Site 300. 

Presenters will include Marylia Kelley, Tri-Valley CAREs’ Executive Director, Scott Yundt, Tri-Valley CAREs' Staff Attorney, and Raiza Marciscano-Bettis, Tri-Valley CAREs' Bilingual Community Organizer.

Nuclear weapons activities at the Site 300 high explosives testing range have resulted in hundreds of documented toxic and radioactive releases to our air, soil, groundwater and surface waters. These activities are ongoing and pose danger to our communities.

The EPA placed the Site 300 in the Superfund list as one of the most contaminated sites in the USA. Site 300 is an 11-square mile experimental test site located southwest of Tracy, joined the list in 1990.

The EPA has calculated that the largest off-site groundwater contaminant plume could affect City water wells. If that occurs, it is estimated to result in an additional one cancer for every thousand residents drinking the water. The cleanup timeframe is multi-generational and will take 50-80 years.

Tri-Valley CAREs experts and staff will offer updates on the plan to increase the size of bomb blasts in the open air at Site 300. We will also discuss the government’s new environmental impact process that will determine which programs get authorized at Site 300 and how much pollution will spew into our communities.

We at Tri-Valley CAREs are open to hearing new strategies and connect with other organizations that may want to work together for the same purpose.

Join us to talk about community concerns, health effects, past actions at Site 300 and alternatives we recommend for the future. For more information visit,

Raiza Bettis,
