Keller Canyon Landfill Investigation

Contra Costa Health Services (CCHS) is investigating the possibility that soil that may have contained radioactive material was improperly taken to the Keller Canyon Landfill in Pittsburg.

The soil came from the cleanup of the Hunters Point Naval Shipyard in San Francisco. The U.S. Navy is overseeing the cleanup.

The shipments of soil and other material occurred from 2009 to 2017. Keller Canyon Landfill is not accepting any loads from the shipyard now.

In April 2018 Contra Costa County became aware that a contractor involved with the cleanup deliberately falsified radiological sampling data for soil that remained at the San Francisco site.

Sampling data from the same contractor was used to determine what landfills the soil being moved offsite could legally go to.

CCHS is in the process of evaluating and selecting a qualified and experienced consultant to provide technical assistance in assessing community concerns and providing recommendations on next steps to address the potential, inappropriate disposal of waste material from Hunters Point.
