San Francisco health officials press Navy for climate-risk studies as community presents biomonitoring data

Susan Phillip, director of the population health division and San Francisco—s health officer, told the Department of Public Health Commission that the department has been intensifying engagement on the Hunters Point Naval Shipyard cleanup and submitting technical comments to federal regulators reviewing the Navy's five-year report. The report, required under the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), evaluates whether remedies remain protective of human health and the environment.

"We at DPH are following along very closely to understand the key technical issues involved and also to understand the community and expert input and reactions," Phillip said, describing the department—s interdisciplinary team and its outreach to Bayview-Hunters Point residents and advocacy organizations. She said DPH does not hold a formal regulatory role while the Navy conducts cleanup, but that it will assume a formal regulator role if and when land is deemed acceptable for transfer to the city.

DPH staff highlighted three priorities that they pressed in written technical letters and interagency conversations: clearer, plain-language communication to the community; parcel-specific climate-resiliency studies to assess groundwater and sea-level impacts on remedies; and greater transparency about possible contaminant movement beyond fenced shipyard parcels. Phillip said the Navy has committed to more detailed parcel studies on climate impacts and that DPH has opened quarterly technical discussions with U.S. EPA and other regulators.

Community members urged faster, on-the-ground steps. Tanya Randall of the Marie Harrison Community Foundation asked the city and Navy to install industrial-grade dust control at fence lines and called for groundwater studies to detect migration of contamination. "Every second we wait, somebody else can die," she said.

A representative from the Hunters Point Biomonitoring Foundation presented preliminary biomonitoring findings she described as "quite, dramatic," saying a small cohort study found radionuclides associated with the shipyard in some participants. "There are few places in, the world where you can be exposed to uranium 235, plutonium 239, in excessive concentrations," she said, and said she would submit raw data for DPH review.

Phillip and her team welcomed the data for technical review but cautioned that DPH—s role during cleanup is largely to provide technical comment and advocacy to regulators. She said DPH submitted three technical comment letters on draft materials and intends to continue pressing for stronger community-facing communications, for regulator-led answers on where contaminants may have migrated, and for transparent parcel-level climate analyses slated to appear in reports in 2025 and beyond.

Commissioners pressed DPH for follow-up on adjacency impacts, timelines, and how comments are addressed by the Navy. Phillip said the Navy accepted some changes (notably commitments on climate-resiliency assessments) but in other areas opted to stay with its planned sampling approach after consultation with regulators. She described plans to build DPH epidemiology and analytic capacity and to consult academic partners to analyze potential health impacts.

The commission received a mix of technical requests and urgent appeals: community groups urged immediate dust-control measures at fence lines and clearer, regular reporting back to neighborhood residents; DPH pledged to provide more detailed updates and to continue coordinating with federal and state regulators as the Navy refines its remedies.
