The environmental and radiological cleanup program at the former Naval Station Treasure Island (NSTI).


Public health and safety are the Navy's priorities in the cleanup of the former Naval Station Treasure Island. The Navy understands the concerns raised by residents and community organizations and continues its commitment working with regulatory partners to complete the investigation process and radiological/chemical cleanup. The Navy's goal is to transfer safe and habitable property to the Treasure Island Development Authority that meets all environmental regulations for local reuse and economic development. 

The entire footprint of Treasure Island has been evaluated for the likelihood for radiological contamination. Radiation levels in accessible areas at Treasure Island are consistent with background levels throughout the Bay Area. 

The Navy follows a deliberate, iterative and thorough regulatory clean-up process that is defined in the Comprehensive Environmental Response, Compensation, and Liability Act. This means that decisions are updated over time, as new data or information is collected.  The process ensures regulatory vetting, stakeholder involvement and public awareness about the clean-up actions that are selected and implemented to protect the environment and community prior to any property parcels being transferred to the City of San Francisco for productive reuse.  

Multiple regulatory agencies have concluded that even as clean-up requirements at NSTI evolved, there was no risk to human health and safety in residential areas.  These findings were also confirmed with independent evaluations by the California Department of Public Health (CDPH).  The state regulatory agencies, including the California Department of Toxic Substances Control (DTSC) and CDPH, review all work plans, scan results, site information and clean-up data and have not identified any unacceptable risk to those who live and work at NSTI.  While there are certain areas of NSTI that are still undergoing investigation and cleanup, those areas have physical barriers in place to prevent public access. 

Naval Station Treasure Island is safe for residents, employees and visitors.  The Navy values the health and safety of the community and will continue to transparently provide information on the remaining cleanup by sharing important updates through the Restoration Advisory Board (RAB), quarterly meetings, Base Realignment and Closure website, newsletters and public notices.
