The U.S. Navy concealed deadly plutonium contamination from San Francisco residents for nearly a year, exposing families to cancer-causing radioactive particles while violating federal safety protocols at a site planned for 10,000 new homes.
Story Highlights
- Navy detected airborne plutonium-239 at twice federal safety levels in November 2023 but waited 11 months to notify residents
- Contamination occurred at Hunters Point Naval Shipyard, adjacent to residential neighborhoods and slated for massive redevelopment
- Military violated its own workplan requiring bi-weekly data sharing with regulators, potentially endangering public health
- Pattern of Navy misconduct includes previous accusations of falsifying radioactive test results in 2023
Government Coverup Endangers Families
Navy environmental coordinator Michael Pound confirmed detection of airborne plutonium-239 during asphalt-grinding operations at the contaminated Superfund site. The readings measured roughly twice the federal action level, indicating dangerous exposure risks to nearby residents. Despite mandatory reporting requirements, the Navy deliberately withheld this critical safety information from San Francisco’s Department of Public Health for almost a full year.
This brazen violation of the Navy’s own workplan demonstrates institutional negligence that prioritizes cost savings over American lives. The delayed notification prevented families from taking protective measures during the extended contamination period. Environmental advocates note this represents part of a disturbing pattern where military interests consistently override public safety concerns at the 866-acre site.
Cold War Legacy Threatens Future Development
Hunters Point Naval Shipyard served as a staging ground for nuclear weapons testing during the 1950s, where the Navy decontaminated 79 irradiated ships from Pacific Ocean nuclear tests. The facility also housed secret research laboratories where animals were injected with radioactive materials. Nuclear experts estimate approximately 2,000 grams of plutonium-239 remain buried throughout the shipyard, with inhalation of even one-millionth of an ounce causing cancer with virtually 100% certainty.
San Francisco plans to construct up to 10,000 housing units on this contaminated land, making transparency absolutely critical for future residents’ safety. The Navy’s proposed cleanup involves capping the property with just four inches of clean dirt, a solution critics consider woefully inadequate for containing such deadly radioactive materials. This approach undermines fundamental Constitutional protections by knowingly exposing American families to preventable health hazards.
Regulatory Failure Enables Military Misconduct
The Environmental Protection Agency designated Hunters Point as a Superfund site in 1989, yet federal oversight remains inadequate to prevent Navy deception. The EPA claims 90% of the site requires no radiation testing despite radioactive materials regularly appearing across the yard. This regulatory failure enables the military to avoid spending billions on proper cleanup while transferring contaminated land to unsuspecting civilians.

Steve Castleman of Berkeley Law’s Environmental Law Clinic pursues litigation claiming the government fails to meet strengthened cleanup standards. Jeff Ruch from Public Employees for Environmental Responsibility characterizes the situation as “one thing after another,” questioning what additional contamination remains hidden from public view. The Navy’s contradictory statements about retest results showing non-detectable levels further undermines credibility and suggests potential data manipulation to avoid accountability.
